ABSTRACT

“-

,-

.-

The habitat, distribution and abundance of juvenile flaffishes within the inshore waters of the

Kodiak Archipelago, Alaska are examined during this ongoing interannual study. The overall

objectives of this project are to (1) identify nursery grounds for juvenile flaffishes, (2) characterize.

those areas according to physical and biological parameters, and (3) develop indices of relative

abundance for as many species as the data allow. We describe distribution for ages-0 and - 1 flaffishes

of each species versus location, depth distance within (+) or outside (-) a bay, temperature, salinity,

sediment type, percents gravel sand, mud, organic content and carbonate content in the substrate, tidal

stage and sunrise.

Data collected during 1991 and 1992 suggest the following conceptual models of flatfish

distribution based primarily on depth and substrate. Age-O rock sole are found predominantly in water

depths less than 50 m on sand or mixed sand substrate within 10 km of bay mouths. Age-O flathead

sole are found predominantly in water depths greater than 40 m on mud or mixed mud substrate

throughout bays. Age-0 Paciftc halibut are found predominantly in water depths less than 40 m on

mixed sand substrate near or outside mouths of bays. Age-l yellowfin sole are found predominantly in

water depths less than 40 m on mixed substrate at upper reaches of bays. Based on graphical analyses,

these conceptual models appear to appropriately describe Chiniak Bay collections during August 1993

and August 1994.

EXECUTIVES UMMARY OF RESULTS

This study was an interannual exarnination of the habitat parameters, distribution and

abundance of juvenile flattishes near Kodiak Island, Alaska (Figure l), which focused on identifying

flattish nursery habitat and developing an index ofjuvenile recruitment. Five cruises were conducted in

association with this study, including cruises in Chiniak Bay during 1993 (KI9301 and KI9302) and

1994 (Kl9401 and KI9403, and a cruise in KazakofBay during 1994 (KI9402).

During prior fund& samples were collected in 1991 and 1992 within all major bays of

Kodiak Island. The 1991 and 1992 trawl samples and physical data formed the basis of conceptual

models of age-0 flatfish nursery habitat around Kodiak Island (Norcross et al. 1995A). Those models

were mod&d slightly by the results of this study, as follows. Both age-0 and age-l arrowtooth

flounder are found in water depth >20 m on sandy mud and muddy sand near the bay mouth. Age-O

flathead sole are predominantly in water depths greater than 20 m on mud or mixed mud substrate

throughout bays. Age-l 0athead sole are found in greatest abundance in depths >20 m on sandy mud

and muddy sand throughout the bay. Age-O Pacific halibut are found predominantly in water depths

less than 40 m on mixed sand substrate near or outside mouths of bays. Age-1 yellowfin sole are fbund

predominantly in water depths less than 40 m on mixed substrate at upper reaches of bays. Age-O rock

sole are found predominamly in water depths less than 50 m on sand or mixed sand substrate within 10

km of bay mouths. Age-l rock sole are mainly in depths ~40 m on sandy substrates throughout the

hY.

Chiniak Bay/August 1993 (KI.9301)

The cumulative CPUE of eleven species of flat&h captured at the 28 stations sampled during

August 1993 within Cbiniak Bay (Wornens, Middle and Kalsm Bays: KI9301) was 2,798, for an

average CPUE of lW101 flatiishe&tation. In order of decreasing abundance, flaffishes include

Uatbead sole (N=1342), rock sole (N=959), yellowhn sole (N=221), Pacific halibut (N=129),

arrowtootb flounder (N=69), butter sole (N=39), Alaska plaice (N=16), starry flounder (N=l l),

English sole (N=8), Dover sole (N=3), and sand sole (N=3). Age-0 was the numerically dominant age

class collected of arrowtooth flounder, Pacific halibut, rock sole, and English sole. Age-l fishes were

caught most often of tlathead sole, yellowfin sole, Alaska plaice and sand sole. Older specimens

dominated catches of Dover sole, stany flounder and butter sole.

Arrowtooth flounder of ages-0 and -1 were distributed with similar patterns during KI9301.

Age0 arrowtooth flounder (N=46) were caught at 12% of stations. The mean number of age-0

fish/tow was 1.X2.3, and the largest catch was 12 fish/tow. Age-l arrowtooth flounder (N=18) were

caught at 21% of stations. The mean number of age-l fish/tow was O.M.5, and the largest catch was

eight fish/tow. Age-0 fish were caught between 20 and 80 m and age-l 6sh were caught from 30 to 80

m water depth. Both ages were collected from outside to the head of the bay. Age-O fish were caught

primarily ova sandy mud and gravel, while age-l tish were nearly always caught over sandy mud.

Ages-O and -1 flathead sole were distributed siiarly during KI9301. Age-O flathead sole

(N=520) were caught at 43% of stations. The mean number of age-0 fish/tow was 13.4h38.4, and the

largest catch was 166 fish/tow. Age-l flathead sole (N=611) were caught at 61% of stations. The

mean number of age-l &&tow was 15.&31.4, and the largest catch -,~as 122 fish/tow. Both ages

W~capturediXliXlcreasin g abundances from 10 to 70 m. Age-O fish increased in abundance from

outside to the head of the bay, but this pattern was not apparent for age-l flathead sole. Age-O

flathead sole were primarily caught on sandy mud, while age-l fish were caught on sandy mud and

muddy sand. They increased in abundance with increasing percent mud in the substrate.

Age-0 Pacific halibut (N=126) were caught at 46% of stations during KI9301. The mean

number of age-0 Stow was 5.WO.6, and the largest catch was 60 &h/tow. During August 1993,

age-0 Pa&c halibut (N=126) were all caught in <30 m depth, f?om 3 km inside the bay to the head.

They were caught mainly over sand and muddy sandy gravel, but a few fish were caught on sandy mud

and muddy sand. They were slightly more abundant with increasing percent sand in the substrate.

Age-1 Pacitic halibut (N=2) were caught at 11% of stations during KI9301. The mean

number of age-l fish/tow was O.M.3, and the largest catch was one fish/tow.

No age-0 yellowfin sole were caught during KI9301. Age-l yellowfin sole (N=130) were

caught at 50% of stations. The mean number of age-l fish/tow was 4.ti12.4, and the largest catch

was 65 fish/tow. Age-l yellowiin sole were caught only in depths GO m, from 3 km inside to the head

of the bay, i?om 9.8 to 12.O”C and 31.2 to 32.4 PSU. They were caught primarily over muddy sandy

gravel and muddy sand, with lesser abundances over sand and sandy mud. Age-l yellowtin sole

increased abundauce as the proportional amount of sand increased in the substrate, and decreased with

increasingly muddy substrate.

Ages-0 and -1 rock sole were sometimes captured in the same strata during IU9301. Age-0

rock sole (N-687) were caught at 54O/a of stations. The mean number of age-0 fish/tow was

39.563.8, and the largest catch was 276 fish/tow. Age-l rock sole (N=200) were caught at 64% of

stations. The mean number of age-l &b/tow was 6.&l 1.3, and the largest catch was 61 fish/tow.

Both age-0 (W687) and age-l (N=ZOO) rock sole were caught from 0 to 70 m depth. Age-O fish were

3
most abundant deeper than 30 n-r, and age-l fish was most abundant between 20 and 40 m. Age-O

rock sole were caught in increasing abundances from the mouth to the head of bays, while age-l rock

sole were most abundant near the mouth. Age-O rock sole were most abundant over muddy sandy

gravel, sand and muddy sand; age-l fish were most abundant over gravel. Both age-0 and age-l rock

sole decreased slightly in abundance as the proportional amount of mud in the substrate increased.

Chiniak Bay/November 1993 (KI.9302)

The cumulative CPUE of nine species of flaffish from 10 stations in Womens and Middle Bays

during KI9302 was 968, for an average CPUJZ of 97*99 flaffishe&ation In order of decreasing

abundance, these fishes include rock sole (N=352), flathead sole (N=306), yellowfin sole (N=140),

arrow-tooth flounder (N=130), Pa& halibut (N=18), butter sole (N=l l), Alaska plaice (N=S), Dover

sole @?=3), starry flounder (N=2). During November 1993 catches of age-0 flatfishes were most

prevalent for arrowtooth flounder, flathead sole, Pacific halibut and rock sole. Age-l fishes were most

numerically dominant of Dover sole, yellowfin sole and Alaska plaice. Age-22 fishes were captured

most often of starry flounder and butter sole.

Ages-O and - 1 arrowtooth flounder were distributed in a siiar manner during KI9302. Age0 arrowtooth flounder (N=ll6) were caught at 40% of stations. The mean number of age-0 fish/tow

was 11.6a23.4, and the largest catch was 67 fish/tow. Age-1 arrowtooth flounder (N=13) were

caught at 20% of stations. The mean number of age-l fish/tow was 1.3S2.8, and the largest catch was

eight fish/tow. Arrow-tooth flounder of both ages were only captured in water >30 m, near the mouth

of Middle Bay.

Age-O flathead sole (N=123) were caught at 70% of stations during KI9302. The mean

number of age-0 fish/tow was 12.31t26.2, and the largest catch was 85 &Mow. Age-O flathead sole

(N= 123) were captured at ah depths examined and at all distances from the mouth of the bay.

Age-l flathead sole (N=l19) were caught at 20% of stations during KI9302. The mean

caught at ail stations within bays, in depths less than 40 m

Age-l halibut (N=3) were caught at 10% of stations during IU9302. The mean number of

age-l fish/tow was 0.3&l. 1, and the largest catch was three fish/tow. Age-l halibut were caught at one

station near the mouth of Middle Bay, in 30 - 40 m depth.

Age0 yellow-h sole (N+) were caught at 30% of stations during KI9302. The mean number

of age-0 fish/tow was 0.9zt1.7, and the largest catch was 4 fish/tow. Age-O yellowfur sole (N=9) were

KI9401 was 989, for an average CPUE of 82=t56 flariishe&ation. In order of decreasing abundance,

the nine species of flat&h collected during KI9401 were flathead sole (N=426), rock sole (N=354),

yellow&r sole (N=135), Pacific halibut (N=55), butter sole (N=12), arrowtooth tlounder (N=2), rex

sole (N=Z), Alaska plaice (N=l) and sand sole (N=l). During June 1994, catches of age-0 tlatftshes

were most prevalent only for Pacific halibut, while age-l fishes were most numerically dominant of rex

sole, flathead sole and rock sole. Age-22 fishes were captured most often of yellowfin sole, butter

sole, Alaska plaice and sand sole. One age-0 and one age-22 arrowtooth flounder were caught.

Age-O arrowtooth flounder (N= 1) were caught at 8% of stations during KI940 1, for a mean of

0.110.3 fish/tow. The age-0 tish was caught in 20 - 30 m, near the head of K&n Bay.

Ages-O and -1 flathead sole were captured in the same strata during KI9401. A single age-0

was caught during KI9401 (8% of stations during KI94Ol,O.lM.3 Mtow). This fish was caught at

the head of Kalsii Bay, in ~20 m depth. Age-l flathead sole (N=265) were caught at 58% of stations

during KI9401. The mean number of age-l fish/tow was 22.1S7.7, and the largest catch was 114

fish/tow. The single age-0 flathead sole was caught at the heed of Kalsin Bay, in <20 m depth. Age-l

flathead sole (N=265) were primarily caught well within K&in Bays, in depths 20 - 60 m.

Age-O halibut (N=54) were caught at 75% of stations during KI9401. The mean number of

age-0 fish/tow was 4.515.6, and the largest catch was 19 fish/tow. They were only caught in water

<IO m deep and on the flood tide. No age-1 halibut were caught.

Age-O yellowfin sole @MO) were caught at 58% of stations during KI9401. The mean

number of age-0 fish/tow was 5.M8.8, and the largest catch was 31 fish/tow. Age-O yellowtin sole

were only captured in ~30 m water depth, from 3 km within to the head of the bay. Age-l yellowtin

de could not be separated from older fishes, and are not discussed.

Age-O rock sole (N=57) were caught at 42% of stations during KI9401. The mean number of

age-0 fish/tow was 4.e8.4, and the largest catch was 26 fish/tow. Age-O rock sole were all caught in

less than 40 m water depth, near the head of K&ii Bay.

Age-l rock sole (N=172) were caught at 67% of stations during KI9401. The mean number

of age-l fish/tow was 14.4~15.5, and the largest catch was 41 fish/tow. Age-1 rock sole were caught

in <JO m water depth, in large abundances from the mouth to the heads of bays.

Chiniak Bay/August 1994 (KI9403)

The cumulative CPUE of 12 tlatfish species at 27 stations examined during August 1994

sampling in Middle and Kalsii Bays (KI9403) was 4486, for an average CPUE of 166a182

flatfishe&tation. In decreasing order of abundance, these species include rock sole (N=2,461),

t&head sole (N=901), arrowtooth flounder (N=678), Pacific halibut (N=284), yellowfin sole (N=76),

butter sole (N=36), English sole (29), starry flounder (N=7), sand sole (N=5), Alaska plaice (N=4), rex

sole (N=3) and Dover sole (N=2). During August 1994 age-0 was the numerically dominant age class

collected of arrowtooth flounder, rex sole, Pacific halibut, rock sole, and English sole. Age-l fishes

were caught most o&n of flathead sole and yellowtin sole. Age-0 and age-l were equally dominant

5
age classes for starry flounder. Older specimens (age->2) dominated the catch of Dover sole, butter

sole and sand sole. Equal numbers of age- 1 and age-z2 Alaska plaice were captured.

Age-0 mowtooth flounder (N=663) were caught at 55.6% of stations during KI9403. The

mean number of age-0 fish/tow was 12.31t32.4, and the largest catch was 157 fish/tow. Arrowtooth

flounder was the second most abundant age-0 fish. Age-O arrowtooth flounder were found in all

regions of the bays (-2.5 to 6.5 km from the bay mouth), from 20 to 100 m water depth and on all

substrates sampled.

Age-l arrowtooth flounder (N=3) were caught at 11.1% of stations during KI9403. The

mean number of age-l fish/tow was O.lti.3, and the largest catch was two fish/tow. Age-l

arrowtooth flounder were only found outside the mouth of the bays (- 1.8 to -2.4 km), Corn 50 to 80 m

water depth and on sand or muddy sand substrate.

Age-O (N=358) and age-l (N=385) flathead sole were found in nearly equal abundance, and

the distribution parameters of age-0 and age-l fish were nearly identical. Both ages were caught at

44.4% of stations during IU9403. The mean number of age-0 fish/tow was 10.6a41.1, and the largest

catch was 271 fish/tow; the mean number of age-l fish/tow was 9.9~24.5, and the largest catch was

135 fish/tow. Flathead were found in waters 10 - 90 m, in increasing abundance to 55 m depth and in

decreasing abundance with fixther increasing depth. They were -2.4 to 7.7 km Corn the mouth of the

bay, but neither age was collected at the head of either Kalsin or Middle Bay. Age-O and age-l

flathead were found on muddy sand and sandy mud substrate, with abundances generally increasing

with increasing percent mud and decreasing with percent sand.

Age-O Pacific halibut (lV= 282) were caught at 5 1.9% of starions during Kl9403. The mean

number of age0 fish/tow was 20.3k18.2, and the largest catch was 68 fish/tow. Ages-O and -1 (N=l)

Pa&c halibut were found only in depths under 50 m, primarily under 30 m While halibut were found

throughout and outside the bays (age-0 6om -1.6 to 8.2 km and age-l at 2.4 km from the bay mouth),

most were found at the heads of JIMsin and Middle Bays coincident with these depths. Age-O halibut

were collected over sand, muddy sand and sandy mud substrates and the age-l fish was on sand

substrate.

Age-O was the least abundant group of yellowfin sole captured during KI9403 (N=3). Age-O

yellowfin sole were caught at 7.4% of stations. The mean number of age-0 fish/tow was 0. MO.3, and

the largest catch was two fish/tow. Age-O yellow-fin were found only outside the mouth of Kalsin Bay

(-0.7 to -1.6 km). Age-O fish were found in 20 - 50 m on sand and gravel substrates.

Age-l yellowfin sole (N=25) were caught at 22.2% of stations during IU9403. The mean

number of age-l &h/tow was 5.M9.9 and the largest catch was 43 fish/tow. Yellowfin sole was the

third most abundant (N=25) age- 1 fish. Age- 1 yellowlin were found throughout and outside the bays

(-0.7 to 8.2 km from the bay mouth). Age-l fish were found in 0 - 40 m on sand and muddy sand

substrates.

Ages-O and -1 rock sole had similar distributions during KI9403. Rock sole was the most

abundant (N=2,219) age-0 fish and the second most abundant (N=183) age-l fish. Age-O rock sole

were caught at 66.7% of stations. The mean number of age-0 fish/tow was 168.OU94.5, and the

largest catch was 680 fish/tow. Age-l rock sole were caught at 5 1.9% of stations during KI9403. The

mean number of age-1 &h/tow was 8.7H.8, and the largest catch was 36 fish/tow. Age-O and age-l

rock sole were found outside and throughout the bays (-2.4 to 8.2 km from the bay mouth) in depths

up to 80 m, but both ages were primarily concentrated in less than 50 m water depth. Both ages were

sole abundances increased with increasing percent of sand and decreasing percent of mud.

Kazakof Bay/August 1994 (KI9402)

The cumulative mean CPUE flaffiswstation of flatfishes Tom quantitative tows at 29 stations

examined during August 1994 within Kazakof Bay (KI9402) was 440, for an average CPUE of 15&l 8

flat&es/station. Listed in decreasing order of abundance, these species include Mead sole (N=275),

yellowfin sole (N=l 11). rock sole (W47), Pacific halibut (N=4) and English sole (FM). Catches of

age-0 fish were most prevalent for Pacific halibut, rock sole and English sole. Age-l was the

numerically dominant age captured of flathead sole and yellowfin sole.

Age-0 flathead sole (N=85) were caught at 34% of stations during KI9402. The mean number

of age-0 fish/tow was 3.0i6.1, and the largest catch was 27 M/tow. Age-0 fish were captured

primarily down the center of Kazakof Bay; they were not at the head of the bay. They were caught in

20 - 90 m water depth and increased in abundance with increasing depth.

Age 1 flathead sole (N=130) were caught at 48% of stations during KI9402. The mean

number of age-l fish/tow was 4.2~t6.2, and the largest catch was 21 fish/tow. Distribution of age-l

fish was similar to age-0 fish. Age-l fish were not captured at the head of the bay. Age-l flathead sole

were caught in 20 - 100 m water depth, and were most abundant from 40 to 80 m water depth.

Age-O Pacific halibut (N=4) were caught at 3% of stations during KI9402. The mean number

of age-0 fish/tow was O.lM.6, and the largest catch was four fish/tow. Age-O halibut were caught at a

single statisn near the head of Kazakof Bay, in 10 - 20 m water depth. No age-l halibut were caught

during KI9402.

Yellow& sole were not caught as age0 during KI9402. Age-l yellowfin sole (N=92) were

caught at 17% of stations. The mean number of age-l fish/tow was 2.6a10.9, and the largest catch

was 60 fish/tow. Age-l yellowfin were caught in 10 - 40 m water depth, from 13 to 18 km inbay.

Age-O rock sole (N=24) were caught at 170/o of stations during KI9402. The mean number of

age-0 fish/tow was 0.W2.6, and the largest catch was 12 fish/tow. Age-O fish were caught from 0 to

Age-l rock sole (N=19) were caught at 17% of stations during KI9402. The mean number of

age-l fish/tow was O.ti2.2, and the largest catch was 12 fish/tow. Like age-0 fish, age-l rock sole

were caught from 0 to 50 m water depth and 12 to 20 km inbay.
INTRODUCTION

.- Despite the strong economic importance of the commercial and sport fisheries in Alaska and

possible future State and Federal gas and oil exploration in Cook Inlet and the Gulf of Alaska

lmowledge of the early life history of flatfishes in Alaskan waters has been minimal prior to this study.

This study was an interannual examina tion of the habitat parameters. distribution and abundance of

juvenile flatfishes near Kodiak Island, Alaska focused on identifying flaffish nursery habitat and

developing an index of juvenile recruitment. Identification of juvenile flatfish habitat is necessary in

order to protect them from habitat disruption. The index of juvenile recmitment will allow more

efEctive and timely management by regulatory agencies and will ass&t with planning by members of

- -

..-

the fishing community and oil and gas industries.

The commercial fishery for flat&h in Alaska took 267,529 mt in 1989, due to directed

commercial and sport fisheries as well as to commercial bycatch. It is important to identify nursery

areas in order to protect them ITom habitat disruption. Possible future State and Federal gas and oil

exploration in Cook Inlet Sale 149 and Gulf of AlaskaNakutat Sale 158 will benefit from this study

which will identify &fish nursery habitats which may be biologically sensitive areas. The nursery

habitat is characterized by physical parameters including depth, sediment type, position in bay,

temperature and salinity. The linkages between the physical and ecological processes explored here

could aid in prediction of the potential effects of proposed gas and oil exploration and development in

the area on the region’s biological resources.

--

This project continued a long term study begun in 1991 to locate and characterize nursery

areas for flatfishes in Alaska and to develop a juvenile recruitment index for the most abundant species.

Understanding and monitoring an index of juvenile recruitment is important because it is a mechanism

fix testing the health of the ecosystem.

-

Initial selection of sampling locations and sites along the coast of Kodiak Island (Figure 1)

began with the acknowledgment that the coastline of the Gulf of Alaska is more rugged and has a

greater tidal range than flatfish nursery areas in many other locations around the world. Most of the

Gulf coast of Alaska is completely inaccessible except by large vessel because of lack of roads and

extremes of weather. Kodiak Island is representative of the coastline of the Gulf of Alaska because it

provides a variety of habii from shallow, tine-grained tidal flats to deep and rocky areas. Kodiak

Island was chosen as the sample site because it has (1) a UAFVSFOS lab for staging of field work, (2)

sites near town which are accessible by small boat, (3) a large trawl fleet available for charter to remote

areas of the island, (4) an informed and concerned citizenry who wish to protect their resources and

their fishery-based economy. Chiniak Bay is near the town of Kodiak and is the only region of Kodiak

Island which is easily accessible via road from the town of Kodiak. Chiniak Bay encompasses three

inner bays which are protected to varying degrees (Figure 1: Womens, Middle and K&in Bays) as well

as providing reiatively accessible and unprotected zones outside the mouths of these bays.

Sample collection was continued during 1993 and 1994 as a result of this fund& collections

were limited to Chiniak Bay during 1993, and to Chiniak Bay and Kazakof Bay (on Afognak Island)

during 1994.

8
Bevious work

Prior funding provided two years of sampling (1991 - 1992) during which all major bays of

Kodiak Island were examined in order to form a broadly based characterization of flatfish nursery areas

around Kodiak. We described fish distribution versus the parameters of location in the bay, depth,

bottom temperature, bottom salinity and sediment type (Norcross et al. 19954 Norcross et al. 1995B).

Distributions overlapped for the most abundant juvenile flatflshes (ages-0 and 1 rock sole, yellowfin

sole, flathead sole and Pacific halibut), yet patterns of peak abundance were unique to each of these

species.

The following conceptual models of the physical parameters most descriptive of flatfish

nurwy habitat have been postulated based on 1991 - 1992 distribution of flatlishes around Kodiak

Island (Norcross et al. 1995A). Age-O rock sole are found predominantly in water depths less than 50

m on sand or mixed sand substrate within 10 km of bay mouths. Age0 flathead sole are found

predominantly in water depths greater than 40 m on mud or mixed mud substrate throughout bays.

Age-O Pacitic halibut are found predominantly in water depths less than 40 m on mixed sand substrate

near or outside mouths of bays. Age-l yellowfin sole are found predominantly in water depths leas

than 40 m on mixed substrate at upper reaches of bays.

The current project describes and analyzes the recruitment of juvenile flatti&es to inshore

waters of Kodiak Island, Alaska. Analysis of data collected in Chiniak Bay during 1992 was funded

partially and during 1993 and 1994 was funded primarily by the Coastal Marine Institute. Dietary

analysis of flatishes captured during 1991 was funded partially by Coastal Marine Institute.

OveraIl ?+ogram Go& and Objectives

1 . To identi@ nursery areas for juvenile flatfishes,

2. To characterize those nursery areas according to physical and biological parameters, and

3 . To develop indices of relative abundances for as many juvenile flat&h species as the data allow.

Background Informahon

Populations of thirteen Alaskan species of flatihes are found near Kodiak Island (Rogers et

al. 1986, Norcross et al. 1993, 1995A). The prime targets for commercial fisheries are Pacific halibut

(H@oglossu.s stenolepis), flathead sole (HppogZossoiides elarsodon), rock sole (Pleuronectes

bilineatw), rex sole (Errex zuchirus) and Dover sole (Mirrostomu paci$cu.s). There are also directed

lisheries for English sole (Plewonectes vettdw) and stany flounder (Pkztichthys steilatus). By-catch

includes yeilowlin sole (Pleuronectes arper), Alaska plaice (PIeuronectes qua&itubercukuW), butter

sole (Pleuronectes isolepis) and sand sole (Psettichthys mek.mostictus) which are marketed

secondarily. There is currently an attempt to develop a fishery for arrowtooth flounder (Atheresthes

stomias) to be used in surimi. Additionally, Pacific sanddab (Citharichthys sora%s) has occasionally

been captured near Kodiak (Norcross et al. 1993).

Relative abundance of species and community composition changes Tom bays across the

Alaskan continental shelf; with most species of fish increasing in sii with depth. This indicates shallow

areas are important as nursery areas in Alaska (Rogers et al. 1986).

9
Preferred conditions of nursery areas for flatfishes

Little information is available on flat&h nursery habitat in Alaskan waters. although the highest

mortality of fishes is during the larval and juvenile stages (Moyie and Cech 1988). However, nursery

habit has been described for fladishes in other regions of the world. Intertidal zones, shallow coastal

areas, protected bays and estuaries are oilen considered vital as nursery areas for flatfishes (e.g. Tyler

1971, Giison 1973, van der Veer and Bergman 1986, Tanaka et al. 1989). Abundance and size

distributions of juvenile flatfishes have been related to depth, sediment siie and food availability.

Flat&h nurseries are uswIly in shallow waters, often in less than 10 m @hvards and Steele 1968,

Allen 1988, van der Veer et al. 1991), on substrates of silt, mud, and line to coarse sand (Poxton et al.

1982, Wyanski 1990). Shallow bays and estuaries are thought to serve as excellent nursery areas and

ideal feeding habitat because of high insolation of the bottom, high water temperatures and the

particular sediment types found in protected waters (Pearcy and Myers 1974), in addition to the good

supply of nutrients Tom land drainage (Pihl and Rosenberg 1982).

Substrate type, current velocity, depth, salinity and food availabiity may help determine where

flatfish initially settle, and may also guide the distribution of older individuals. Sediments in flatfish

nursery areas are genemlly silt, mud or tie to coarse sand (Poxton et al. 1982, Wyanski 1990). A

dominant substrate of gravel or coarser materials reduces the suitability of an area to serve as a nursery

(Rogers 1985). Burying abiity of juvenile flaffishes probably depends on several f&tot-s associated

with sediment in addition to grain size (e.g. particle compacting, cohesion biding by activity of

benthic fauna) (Gibson and Robb 1992). Abundance of young-of-the-year flatfishes is profoundly

‘duenced by water depth, a phenomena shown by Riley et al. (198 1) for species in the English North

!&a. Newly metamorphosed plaice of the genus Phwronectes were found to actively select shallow

depths in the North Sea (Edwards and Steele 1968).

Depth distribution changes with age, and may limit both intra- and interspecitic competition

among &dishes (Poxton et al. 1983). Competitive tish species may reduce range overlap by

maintaining localized feeding. A nursery may be partitioned into areas dominated by separate species

or intraspecific age groups (Edwards and Steele 1968, Harris and Hartt 1977, Smith et al. 1976, Zhang

1988). The correlation between mean length of fish and depth for some species is sign&ant (Gibson

1973). Large quantities ofjuvenile rock sole were taken by Harris and Hartt (1977) intertidally in the

Kodiak area with older individuals taken near the mouths of fjords. A reversal of this trend was

exhibited by flathead sole in which larger fish were found toward the heads of Kodiak bays (Blackburn

1979).

Geologic description of the Kodiak Archipelago

- -

_-

The Kodiak Archipelago (Figure 1) is an island arc collision coast in the western Gulf of

Alaska where oceanic crust is being thrust under a thicker, less dense continental plate. Uplifted

subduction zone complexes have given Kodiak a rugged, mountainous relief The topography of the

Kodiak area was strongly afI&ted by heavy glaciation during the Pleistocene. In general, the islands

are erosional, with perhaps as much as 20 to 30% of the shoreline depositional, but only 2.6% of the

total shoreline consists of sheltered tidal flats and marshes (Hayes and Ruby 1979). Local conditions

determine the character and behavior of the sediment, but in generaL mean grail size for Kodiak and

Afognak Island beach sampies generally ranges between very coarse sand and pebbles, with particle

size decreasing seaward, producing a graded sediment distribution (Hayes and Ruby 1979).

1 0
The western coastline of the Kodiak archipelago is backed by steep slopes of glacial till,

leadiig to a coarse-grained beach supplied by glacial deposits. A predominance of sandy beaches is

found on the western coast of Kodiak and within the Trinity Islands due to an abundance of

unconsolidated glacial material with a high percentage of sand. The northwest side is a dramatic

example of glaciation, having steep slopes butted up against straight shorelines with narrow gravel

beaches. The northwest shore is indented by long narrow tjords. Thick deposits of glacial till blanket

the southwest comer of Kodiak Island. Shorelines in this area are generally long and continuous, with

glacial tii contributing sand, gravel and boulders to the beach and coastal sediments. Southwest

Kodiak and the nearby Trinity Islands have fine to coarse grained sediments (Hayes and Ruby 1979).

Bedrock outcrops back the beaches on the east of Kodiak and Afognak Islands, producing

beach sediments which are very coarse grained and homogeneous (Hayes and Ruby 1979). Along

southeast Kodiak, short, wide estuaries tend to mn northeast-southwest, a direction parallel to the

major thrust faults of the island. .Uognak Island and northeast Kodiak have smaIl pocket beaches

eroded by wave action, similar to the southeast of Kodiak. Northeastern Kodiak bays have fine to

coarse grained sand with muddy areas in deeper portions of bays. We have observed the sediment of

southeast Kodiak around Sitkinak Strait and Alitak Bay to be of shell hash and medium to tinegranted

sand.

Rivers draining into the fjords dump large amounts of glacial till, creating deltas of sand and

line gravel. The beaches in Kodiak fjords are variable, but tend to be coarse due to local bedrock

sediment sources. Where rivers empty onto the open coast, sand and gravel beaches occur downdrift

(Hayes and Ruby 1979).

METHODS

Descriph of sample bcutions

Descri@a of Chiniak Bay

Cruises during I993 (KI9301 and KI9302), and two ofthree cruises during 1994 (KI9401 and

KI9403) consisted of land-baaed collections conducted within Chiniak Bay, near the town of Kodiak

Alaska (Figure 1). Kalsin, Middle and Womens Bays were chosen for intensive sampling because they

were near town facilitating land-based operations, and thus could be sampled on repeated days at a

low cost. The NMFS laboratory on the Kodiak Coast Guard Support Center was the base for

sampling operations, and the Fishery Industrial Technology Center (FITC/SFOS/LJAF) provided

vehicles, space for office and laboratory work as well as storage space for gear and frozen samples.

Womens, Middle and K&ii Bays are offshoots of Chiniak Bay (57”4O’N, 152”3O’W)

approximately 10 nmi from the town of Kodiak. Tidal range in this area is approximately 2.5 m.

Because these bays were sampled with a small vessel, extremely shallow colhxtions could be made.

Womens Bay is about 7 km long, with an area of approximately 12 km*. Womens Bay is

more shallow and protected than either Kalsin or Middle Bays. Womens Bay is less than 10 m in depth

at the mouth, but there is a deep hole midbay (2933 m). At the head of Womens Bay, a tidal marsh

extends for nearly 1 km inland. Most of inner Womens Bay is less than 10 m deep.

Middle Bay is about 8 km long with an area of approximately 21 km2. It is intermediate with

regard to depth and protected shoreline than Womens or Kalsin Bays, and has a depth of 50 m at the

mouth. Middle Bay is surrounded by cl%% and at the head of the bay there are marshes behind a sandy

1 1

beach. The shallow areas extend farther from the shoreline of Middle Bay than do the shallow areas of

Kalsin Bay. Inner Middle Bay, approximately 2 km wide, is less than 10 m deep, much shallower than

K&in Bay.

Kalsin Bay covers an area of approximately 34 km’, and is 8 km corn mouth to head. It is a

deep bay with waters in excess of 100 m at the mouth. Nearshore waters drop off rapidly, with waters

of < 10 m depth comprising a narrow zone of< 0.5 km around most of the edges of the bay to 1 km at

the head. Kalsin Bay is surrounded by cliffs except at the head where a marsh extends behind a sandy

beach.

Description of Kazakof L3ay

Cruise ICI9402 during 1994 consisted of land-based collections conducted within Kazakof

Bay, Afognak Island (Figure 1). Ben A. Thomas Logging Camp was the base for sampling operations

and personnel.

Kazakof Bay is a long, narrow bay, covering an area of approximately 60 km’. It opens to the

south along the southern coast of Mognak Island. Kazakof Bay is 20 km long, and the mouth of the

bay is approximately 5 km wide. The bottom contour is steep in near-shore areas along the east and

west sides of the bay. Near the head of the bay, stations could be occupied in depths less than 30 m.

Sample colkdons

General collection pmc&re, all ck.se.s

Four of the cruises were a joint effort between the Institute of Mark Science, University of

Alaska Fairbanks (IMS/UAF) and the National Marine Fisheries Service, Kodiak Laboratory

(NMFYKodiak). Collection gear and sampling vessel used in Chiniak Bay during KI9301, KI9302,

KI9401 and KI9403 were identical, but were not the same as had been used during previous years

(Cruises KI9101, KI9102, KI9201 and KI9202). The vessel used during cruises KI9301, KI9302,

KI9401 and KI9403 was the RJ' Pumkin, a 25 ft Boston Whaler owned and operated by

NMFS/Kodiak. Identical gear was deployed from a 25 ft aluminum skiff in Kazakof Bay during

KI9402. The slightly different sampling procedure used during KI9402 is explained in a following

section; methods used in Chiniak Bay are described in this section. Gear is listed and described in

Appendix 1.

Station numbers were assigned in consecutive order (hereafk referred to as consecutive

station number or CS#) for each cruise. Consecutive station numbers were assigned for ail sites at

which gear was deployed. Usually, a CID, sediment grab and trawl were deployed at each station.

Trawl tow numbers were assigned consecutively at each station whether or not the tow was judged

quantitative. During KI9301 and KI9403, selected stations were examined by NMFS divers using

SCUBA gear.

In addition to the consecutive station numbers which were reassigned on each cruise, many

siies which were sampled annually have been identifkd by a permanent station code. The permanent

station code reflected the bay, depth range and sediment type at which the sample was taken (Table 1).

The “depth” portion of the permanent station codes was assigned based on the depth at low tide; due

to the broad tidal range near Kodiak, the towing depth may appear to be inconsistent with the depth of

the station code. Stations within the same bay, depth and sediment type bad the same permanent

station code regardless of location within a bay, and were considered as replicate stations. Within a

specific bay and depth range, various sediment types were found. Sites witbin one bay of the same

1 2
depth range, but with different sediment types were distinguished by a siigle digit added to the depth

increment (i.e. KB20, KB21 and KB22). AU sampling sites in the same depth increment and sediment

type had the same digit for the specific sediment type (i.e. RR31 and MB31 had the same depth and

sediment type; RR50 and MB52 had the same depth, but different sediment types). With this naming

system, sites for comparison among and within bays were readily apparent.

Substrate was collected for grain siie analysis usiig a 0.06 m’ Ponar grab. Single substrate

samples were taken at nearly every station. Except for dive transect stations where multiples grabs

were taken, we rarely collected replicate substrate samples. Sediient was retained frozen and shipped

to Fairbanks for laboratory grain size analysis. During 1991, 1992 and 1993 (K19101, KI9102,

KI9103, KI9201, RI9202 and KI9301) sediment was subsampled and preserved in lO’?/o form&n for

benthos taxonomy, but following cruise KT9301, we determined not to collect tiher benthos or

analyze benthos collected during 1992 or 1993. KI9201, RI9202 and RI9301 benthos samples were

discarded and no further benthos samples were retained during this project, due to time and fiscal

limitations.

Vertical protiles of salinity and temperature were recorded with a portable SeaBird Seacat

Protiler 19 (CTD). This instrument is a self-contained unit which does not have a real-tiie readout,

and the data were dumped periodically to a portable computer. Replicate CTD casts were collected

only in rare instances. The CTD was allowed to equilibrate for two min. at 1 m depth and was then

deployed by hand until the 10 lb. weight fastened below the sensors touched bottom. The CTD

recorded measurements of temperature, depth and salinity at half second intervals. The array of

temperature and salinity profiles collected during each cruise indicates general patterns of water

movement.

Fishes were sampled using a plumb staffbeam trawl with a double tickler chain adapted from a

design by Gunderson and Ellis (1986). The very small mesh (7 mm square) and codend liner (4 mm)

retains Baffishes as small as 12 mm (Norcross et al. 1993). With a few exceptions, all collections in

1993 and 1994 were made with a 3.05 m (10 ft) beam rather than the 3.66 m (12 fi) beam which had

been used during 1991 w9101, RI9102 & KI9103) and 1992 (RI9201 & KI9202). As in previous

years of sampling, the trawl design was modified via the addition of floats to the ends of the beam and

150 mm lengths of chain knotted to the footrope at 150 mm intervals. In 1993 and 1994, endeavors

were made to sample as slowly as possible in order to tow at a speed comparable to previous years

collections. The tow speed was approximately 0.5 kt for RI9101 and IU9201, 1 .O - 2.0 kt for RI9102

and KI9202, RI930 1, KI9302, RI940 1, K.I9402 and KI9403.

Precise measurements of distance towed were unavailable for many tows, and therefore the

number of fishes captured during each tow was standardized to a 10 min. tow duration. The

standardized catch-per-unit-effort (CPUE) accounts for the value of N being other than a whole

number. Figures report the N of fishes as the nearest whole number (or 1). In exceptional cases the

number of fish plotted on a figure may not appear to equal the N stated in the title. To avoid

conkion, many of these instances are noted on the plot (i.e. *rounded value). The effective width of

the tow was expected to be 0.74 * beam length (Gundemon and Ellis 1986), and was estimated as

2.257 m for the 3.05 m beam and 2.707 for the 3.66 m beam, resulting in an approximate average tow

area of 1000 m2, assuming that the net was towed over a distance of 450 m. Future analyses will be

based on distance CPUE standardized to a 1000 m2 tow area, rather than on tow duration.

While the original hypothesis was that juvenile flaffishes should be found in shallow water on

relatively smooth bottoms, a variety of depths and substrates were sampled. Collections generally were

stratified in 5 m depth increments from 0 to 10 m and in 10 m increments for deeper sites. Trawling

was primarily done during the rising tide and in daylight. The start time of each tow or dive was

quantiieci by minutes after high tide and minutes after sunrise (e.g. -100 signifies 100 minutes before

high tide, 10 signifies 10 minutes after high tide. The same pattern holds for minutes before and a&r

SUllIiSe).

One half to S/8 in. nylon double braided line was put out to achieve a 8:l line:depth ratio at

stations less than 10 m, 5:l ratio for depths 10 - 50 m and 3:l ratio at depths greater than 50 m.

Aboard the R,V Pumkin, (KI9301, KI9401 and KI9403) line was put out by hand through the crab

block. The crab block was equipped with hydraulic power, was used off the starboard to deploy the

grab and CTD, and was pivoted inboard to deploy, tow and retrieve the tow line off the stem. The

trawl was deployed and retrieved off the starboard. A bolt held the crab block in place during

starboard operations, and a line f?om the bow was clipped to the block during trawl operations to

secure the block perpendicular to vessel motion. The tow lime was attached at the port cleat during

tows. Tow speed was approximately 1 .O - 2.0 kt with an estimated 380 - 700 m covered by each tow.

Tow duration was usually 10 min. When the bottom was excessively muddy, we reduced tow time to

5 min. to facilitate sorting and because we expected towing with a clogged net to reduce fishing

efhciency.

Flatfishes and rountishes sampled with the trawl were identified and total length (mm) was

measured in the field. These data were later entered into a database using either a Linmoterra digital

fish measuring board (KI9301) or manual data entry (all other cruises). Large numbers (>lOO) of a

single species were sometimes collected during one tow, occasionally we measured a subsample of the

youngest year-class, all older fishes were measured. During KI9301 and all 1994 cruises, a subsample

of large (>200 mm) flatfishes was examined in the field for stomach contents, sex and maturity stage.

Stomachs, sex and maturity were not examined for any fishes during KI9302. Small specimens of all

flattishes except flathead sole, yellowfin sole and rock sole were retained frozen for possible gut

content analysis. Flathead sole, yellowtin sole and rock sole were not retained, because a large amount

of feeding data had been collected for these species in 1991 (KI9101& KI9102). No weight data were

wllected on fishes during 1993 or 1994.

Trawl/dive transects were established at two stations in 1993 and two stations in 1994.

Similar to tows at all other stations, trawl&e comparisons were conducted primarily on a flood tide

and always during daylight. The beam trawl was towed parallel to, and approximately 100 fi on either

side o$ diver tmsect lines. Trawling was conducted wncurrent with the dives. A @ansect line of II2

or 5/g in. nylon line was weighted at each end by a 15 or 20 pound anchor and deployed at each

station. A large buoy was fastened to each anchor with suflicient 3116 in polypropylene line for the

buoy to float fYeely and mark the diver transect. Two transect lines were generally laid end to end.

NMFS divers worked in teams of two persons; while the tirst diver sampled one transect, the other

diver dove on the adjacent transect. After waiting a minimum of 15 minutes, a diver surveyed the

tmnsect which had just been sampled by the other diver. During both 1993 and 1994 NMFS divers

observed a 2 or 3 ft (0.61 or 0.91 m) swath (dependent upon visibility) along a 600 ft (182.9 m)

transect line and reported on numbers of Batfishes and roundiishes seen concentrating their

observations on tlatishes. An exception to this was KI9403 CM6 (tows 2,3,5 and 7 and dives 2,3,5

and 8) which used a 778 fi (255.2 m) transect line.

Divers differentiated between small, medium and large flatfishes at all stations. Small flat&h

quantitative, but divers were able to ident@ only the larger flatfish to species with certainty. Divers

were able to observe flatfishes as small as 10 mm total length.

G&rtimts within CXniak Bay/August 1993 (KI9301)

Trawling and diving surveys were conducted within Chiniak Bay during 12 - 24 August 1993

(Table 3, Figure 2). The fisheries field crew for cruise KI9301 consisted of Brenda Norcross and

Brenda Holladay of IMSLJAF, both of whom had been involved in field coikxtions of juvenile

flaffishes in 1990 - 1992. The crab field crew included Eric Munk, Susan Payne, Pete Cummiskey and

Bob Otto, all of NMFS/Kodiak. Braxton Dew (NMFS’Kodiak) and Eric Munk performed SCUBA

dives concurrently with KI9301 trawling operations. Eric Munk usually operated the RYPumkin, but

during simultaneous trawling/diving operations, Pete Cummiskey was vessel operator.

Cruise KI9301 (9 sampling days: 12 - 24 August) added to our annual August index of

juveniIe flatfish distribution and abundance in Womens, Middle and K&in Bays. Target species

included flatfishes, tanner crabs and miscellaneous roundfishes and crabs. Collections occurred at new

sites as well as established station sites which had been occupied during previous years. Five stations

were occupied within Womens Bay during KI9301. Womens Bay was previously sampled during

1992 (KI9201), but not 1991. Ten stations were occupied in MiddleBay during KI9301. MiddleBay

was examined intensively during 1991 (IU9101, IU9102 and KI9103) and 1992 (KI9201). Fifteen

stations were occupied in Kalsin Bay during KI9301. Kalsm Bay was sampled intensively during 1991

(KI9101, KI9102 andKI9103) and 1992 (KI9201).

Tows during KI9301 used a 3.05 m or 3.66 m beam. At the first 26 consecutive stations,

fishes and crabs were collected with a 3.05 m beam rather than the 3.66 m beam which had been used

during 1991 (KI9101, KI9102 & KI9103) and 1992 @I9201 & KI9202). At CS#27-30, tows were

conducted with both the 3.05 m and 3.66 m beams in order to compare ease of deployment and catch

collected using the two beams. The shorter beam was easier to manipulate both on deck and during

deployment/retrieval and has since been used in 1993 and 1994 trawling operations.

Sediment was collected at each station during KI9301, and CTD profiles were recorded at all

stations during KI9301 except CS#27-30. Due to operator or equipment error, no CTD data are

available to relate with tows &om the 6nal four stations during KI9301. Twenty-eight stations were

sampled stmce&Uy by beam trawl, including CS#2-9 and CS#l l-30. Successll replicate tows were

collected only at CS#27-30.

Consecutive stations 27-30 during KI9301 were examined repeatedly by trawl and SCUBA

divers in order to create a baseline for quant$ing trawl catches versus diver observations. At each

station, four dives and three (CS#27) or four (CS#28-30) quantitative tows were conducted. Dive

tmnsects were. always 600 fi long, and the trawl was towed for ten minutes.

cdlediovtswithin C'ainiakBayh'i-ovemk1993(K19302)

Cruise KI9302 (Table 4, Figure 3) was conducted by Eric ML& Susan Payne and Brad

Stevens (NMRYKodiak); lMS/SFOS/UAF was not represented. Tanner and other crabs were the

target species. In addition to the target species, flatftshes were collected for this project. Five sampling

days (8,9 and 17 - 19 November) provided a seasonal component to both the flat&h length analyses

and to indices of flat&h distribution and abundance. The only gear deployed successllly was the 3 .OS

m beam trawl. A 1.8 m beam trawl with a net of like mesh but shorter headrope and footrope than the

3.05 m beam trawl was deployed unsuccestiy at CS# 1 and CS#2 Tow#l, after which that gear type

15
was abandoned. The CTD was deployed. but due to equipment malfunction, no data were retrieved.

The sediment grab was not deployed. Three stations were sampled in Womens Bay, and nine stations

were sampled in Middle Bay during KI9302. Kalsin Bay was not occupied during this cruise.

Colcecdbns within Cltiniak Bay/June 1994 (R19401)

Eric Munk and Susan Payne of NMFYKodiak and Brenda Holladay of lMS/uAF collected

data within Chin& Bay during 20 - 21 June 1994 (Table 5, Figure 4). Eric Munk operated the vessel.

The 3.05 m beam trawl was deployed. The CTD was not deployed due to equipment mah%nction

and the sediment grab was not deployed. During KI9401, one station in Womens Bay, four stations in

Middle Bay and seven stations in Kalsin Bay were occupied.

Cid?ections within Chiniak Bay/August I994 (KI9403)

Similar to KI9301, trawling and diving surveys were conducted during KI9403, and target

species included flatfishes, tanner crabs and miscellaneous roundfishes and crabs (Table 6, Figure 5).

The fisheries field crew for cruise RI9301 consisted of Brenda Norcross, Brenda Holladay, Franz

Muter and Sherri Dressel of IMSAJAF. Eric Munk collected crab data. Braxton Dew

(NMFS/‘Kodiak) and Pete Cummiskey performed SCUBA dives concurrently with RI9403 trawling

operations. Eric Munk operated the RG’Pumkin during all consecutive station tows, as well as during

simultaneous trawling/diving operations.

Data were collected at each station by one or more of the following: beam trawl, sediment

grab, CTD and SCUBA divers. Womens Bay was not sampled during KI9403. Of the 12 stations

sampled in Middle Bay, all except CS#23 and 29 were sampled in previous years. CS#23 consisted of

four nonquantitative tows at the head of Middle Bay with no sediment or CTD data collected and is

not included in RI9403 figures. Of the 18 stations sampled in Kalsin Bay, eight were new stations

(CS#13-18 and 24) and 10 had been previously sampled. In KI9403, severai of the new KalSm stations

sampled were deeper and t%rther outside the mouth of the bay than in previous years (CS#13-15, 17

and 18). Consecutive stations 22 and 28 in Kalsii Bay consisted of only non-quantitative tows, and

therefore are absent from fish abundance plots. Sediment and CTD data were collected at CS#28 but

not at CS#22. Sediment samples were retained Tom all stations except CS#22 and 23, for gram size

analysis. Replicate sediment samples were taken only at CS#13 and 14, since tows were made on

different days, and at dive transects CS#6 and 12.

_....

Fii-nine successful CTD casts were recorded, including CTD casts at all stations except

CS#22 and 23, where all tows were nonquantitative. Replicate CTD casts were made at consecutive

station numbers 10, 13, 14,25 and 26 where tows were made on different days (CS#13, 14, 25 and

26), when a sign&ant amount of time passed between tows (CS#26 tow 2 and tow 3) or when

location varied slightly (CS#13 tow 2). Multiple CTD casts were aLso made at the dive tmmects,

CS#6 and 12.

Fishes were sampled at thirty stations with a 3.05 m beam trawl, resulting in a total of 56

quantitative tows at 27 stations (CS#l-21, CS#24-27 and CS#29-30). Replicate tows were made at

CS#6,12,13,25 and 26.

In addition to the trawls completed in KI9403, and as was done in 1993, two stations (CS#6

and 12) were sampled with repetitive tows and SCUBA dives in order to compare the etIiciency of

beam trawl versus SCUBA divers in identi@ng and quantifying flattishes on different bottom types. In

order to make statistical comparisons between beam trawl catches and diver observations, we

16

..-
maximized the number of replicated diver observations and beam trawl catches at these two stations,

Data colIected at the trawl/dive stations sampled during both 1993 and 1994 will be used to determine

whether SCUBA divers may be used interchangeably with beam trawl tows in areas and on substrates

where trawling is ineffective or impossible.

During KI9403, CS#6 and CS#12 were each sampled with 14 quantitative tows and 12 or 16

dives, respectively, over a period of two days. Transect lines were laid end to end in the same manner

as in 1993. Unlike KI9301, when the trawl was towed for 10 min. during trawl/dive comparisons, the

duration of tows during KI9403 was determined by distance, using the transect lines and buoys for

measurement. Unlike 1993, when the dive transects were always 600 fi, the two transects at one of the

dive stations were different lengths on the first day of sampling. On the first day (9 August) at dive

transect station CS#6, the east transect line measured 778 ft (tows 1,4,6,8 and dives 2, 3, 5, 8). On

the second day of sampling transect CS#6 (tows 9-14 and dives 9-12), two 600 fi lines were laid. The

600 fi lines were used for all tows and dives at dive transect CS#12.

All collected fishes were measured, with the following exceptions: age-0 rock sole were

subsampled at CS#18, and age-0 northern sculpin (Lx~~~~Ls borealis) were subsampled at CS#30, since

more than 300 individuals of that year class were captured.

cdleaions within Kazakof Bay/August I994 (KI9402)

Franz Muter, Brenda Holladay and Sheni Dressel (IMSiUAF) collected samples during 2 - 7

August 1994 in Kazakof Bay, Afognak Island usiig a Boston Whaler (Table 7, Figure 6). Brenda

Norcross assisted witl; colIections during 2 August. Franz Muter operated the vessel. SampIing

procedure was slightly different from cruises aboard the RW Pumkin. The crab block was fixed in

place on the starboard, and the trawl was towed Tom and was tied off at the stern.

Samples were collected from 31 stations. Substrate was collected from ail stations, with

replicate grabs at CW4 and 6. Substrate was observed but not retained at CS#20, where no tow was

taken. Sediment grain Size has not yet been examined for KI9402, and will be completed in 1995 - 96.

CTD data are avaiiable for all stations except CS#20. A single CTD profile is representative of both

CM26 and CS#27 because these stations were close together and were occupied within a short time

span Replicate CTD casts were collected at CS#l, 4,6 and 13.

Tows were of variable duration (3.3 - 10 min.), and were collected on both flood and ebb

tides. Tows were attempted at all stations except CS#20, but were often either questionably

quantitative or not quantitative. Tows where the catch did not overflow the codend and the net

appeared to have fished correctly were quantitative. Nonquantitative tows were where the gear did

not fish correctly or where a portion of the catch was lost while retrieving the net. Questionable tows

were where the catch overflowed the codend or where the codend was completely lilled with mud or

kelp.

Sample I%xsing

Avrcessing of physical data

Temperature, saliity and depth data were downloaded to computer disk and processed with

SeaBird CTD software. For all stations, data collected during the 2 min. temperature equilibration of

the CTD were omitted to avoid erratic temperature and salinity spikes. Raw data from the down cast

of the CTD were averaged on 0.1 m intervals for stations <lo m depth, and on 0.5 m intervals for

17
-

.-

-

-

deeper stations, and proties of temperature and salinity were plotted. The distribution of mean bottom

temperatures and bottom salinities were charted for each station.

The distance (km) f?om the station to the nearest position at the mouth of a bay was calculated

tier drawing lines across the mouths of Womens, Middle, Kalsin and Kazakof Bays. The shortest

distance from the station to this line was measured. Stations inside the mouth were designated as

positive distances, and stations outside of bays were assigned negative distances.

kxessittg ofsediment data

The proportional weights of the gravel, sand and mud &ions were obtained for all substrate

samples collected usiig a wet and dry sieving technique (Appendix 2). The Wentworth grade scale

(Sheppard 1973) defined grain Sizes of boulder, cobble, gravel (pebble + granule), sand and mud (silt +

clay). Sediment samples were sieved to determine relative percent at each Phi level of gravel and sand.

The mud fraction was not partitioned into Phi levels. Phi level classiications were calculated for the

gravel and sand fi-actions, but are not reported here. Results of grain size analyses were categorized

afkr Folk (1980) (Table 2). We employed Folk’s classiications with the following exceptions. Folk’s

classiiications of (g)sM and (g)mS (meaning less than 5% gravel) were incorporated within the

categories of sM and mS for our analysis. Additionally, substrates larger than Folk had analyzed (i.e.

containing cobble or boulder) were classiied visually according to the Wentworth scale (Sheppard

1973).

Percent volatile matter and carbonate present in the sediment were obtained by a generally

accepted method (Appendix 2) when s&icient sediment remained tier grain size had been examined.

Percent volatile matter provides an indirect estimate of organic content which may be available as food

for benthic feeding fishes, and percent carbonate is an estimate of shell content within the substrate.

l+ocessing ofjish dizta

Ages of flatfishes were estimated tiom total length using 1) total lengthlfkquency plots of

fishes produced for each cruise, 2) total lengthkquency plots of fishes collected previously in Kodiak

during August (Norcross et al. 1993, 1995A), 3) analysis of regional differences in total lengths of

fishes caught during August 1991 (Norcross et al. 1995B) and 4) additional literature references (e.g.

Hart 1980). Lengthkkquency plots and tabulated flat&h lengths include lengths and counts of

measured 6sh only. The counts therefore are not equal to catch-per-unit-effort (CPUE) values or the

total number of fish captured. Ages could be assigned as 0,l and gt.2 using this method. Without

otolith aging, more precise estimates of ages are not possible.

Abundance of fish was standardized to a 10 min. towing time for aU cruises. Tow CPUE

values were used for comparisons of fishing efficiency between 3.05 m and 3.66 m beams and to

estimate intmstation variability. Ail plots, charts and text reflect the average CPUE of all quantitative

and questionably quanbtive tows at a station, unless otherwise stated. Except for cases which are

mentioned below, the number of fish (N) plotted is a cumulative value calculated from average station

CPUE. Because of standardizing fish abundances to a 10 min. tow and averaging tow abundances

within a single consecutive station, the actual value of N was not always a whole number. N is

reported as the nearest whole number in alI figures. Because of this, there are exceptional cases where

the number of data points plotted may not appear to equal the N stated in the title. To avoid

confkion, many of these instances are noted on plots by an asterisk a&r the N stated in the title. The

N of fish used in CPUE plots of temperature and sahnity includes only those fish captured at stations

18
with temperature and salinity data, and is not always equal to the cumulative CPUE of fishes caught at

quantitative stations. Siiarly, the N of fishes used in CPUE plots of tidal stage and light stage is the

cumulative CPUE of fishes captured at each tow,

The greater quantity and variety of collections during RI9301 and RI9403 allowed analysis of

fish distribution versus more parameters than for KI9302, KI9401, and RI9402 Analyses of RI9302

and RI9401 are limited to examination of 1engWfkquency plots and scatterplots of CPUE versus

average tow depth. Analysis of RI9402 includes length/frequency plots, scatterplots of CPUE versus

average tow depth, distance from the mouth of the bay, bottom temperature and bottom salinity.

Figures reporting data fkom RI9301 and RI9403 include the plots analogous to those prepared for

ICI9402 and additionally include histograms of fish CPUE by sediment type, and scatterplots of CPUE

versus percent gravel, percent sand and percent mud. These plots report the log transformed value of

CPUE (+l) for each station or tow, rather than depicting the average CPUE within a physical

parameter range, as had been presented during previous years of this study. As is standard in fishery

analysis, a logarithmic scale of fish abundances was used on all scatterplots to minimize the

overemphasis of unusually large or small abundance values. On this a logarithmic scale, faint patterns

of increasing or decreasing fish abundance may nevertheless indicate strong trends in relation to the

particular parameter measured.

Data on flatfish distribution and abundance are presented for age-O, age-l and age-22 fish.

Age-22 fish are not discus& in the text, since the category arbitrarily groups a wide assortment of

ages. Text summarizes the presented tables, charts and graphs. Trends mentioned are limited to

conceptual descriptions, as no statistical analyses have been pdormed.

Fish data are reported in alphabetical order by genus and species in accordance with the order

used by the American Fisheries Society (1991).

R-Base (Microrim 1990) was used as a data base manager, but most data summaries, plots

and tables were produced using EXCEL (Microsoft Corporation 1993). CTD proses were plotted

using SYSTAT (Wiison 1990) or EXCEL.

gravelly, s = sandy, m = muddy. The capital letter represents the dominant sediment and lower case letters are lesser

sediment types. Consecutive trawl tow numbers were assigned at each trawling station, regardless of whether the tow was

quantitative (*designates non-quantitative tows). Dive transects were examined by SCUBA divers; dives were numbered

consecutively for each diver at each dive station. A conductivity, temperature, depth (CTD) probe sampled salinity and

temperature at most stations. H indicates no data of this type were retained, ’ indicates an estimated value.

Table 6. Summary of activity during 8 - 19 August 1994 within Chiniak Bay (K19403). Activity is indexed by consecutive station number (CS#).

Explanation of permanent station code can be found In the methods. Sediment codes: G = gravel, S = sand, M = mud, g = gravelly, s =

sandy, m = muddy. The capital letter represents the dominant sediment type and lower case letters are lesser sediment types.

Consecutive trawl tow numbers were assigned at each trawling station, regardless of whether the tow was quantitative; *designates nonquantitative tows. Dive transects were examined by SCUBA divers; dives were numbered consecutively for each diver at each dive station.

A conductivity, temperature, depth (CTD) probe sampled salinity and temperature at most stations. At trawl/dive comparison stations

(CS#8 and 12) multiple CTD and sediment samples were taken at the beginning and end of the day on which the trawls/dives were made, not

immediately preceding each tow. CTD files listed for CS#8 and 12, therefore, refer to all tows/dives made at that station on that particular

day. *“indicates no data of this type were collected/retained. ‘indicates averaged/estimated values.

RESULTS and DISCUSSION

Aging ofjlutjishes

Length anuiyses ufjlutjishes &ring August and November 1993 (K19301& KI9302)

Ages of flatfishes captured in August and November 1993 were estimated using total lengths

(Table 8, Figure 7). Due to past collections during August near Kodiak, estimates of length-at-age

were consistently reliable for age-O, age- 1 and age-12 fish.

For several species, an estimate of growth was possible for the three month time span between

collections. Flaffishes of different species grew at different rates, as evidenced by the shifI of the 5 mm

mode and a comparison of mean length at age. The 5 mm mode of age-0 arrowtooth flounder

increased by 45 mm from 45 - 49 mm to 90 - 94 mm, and the mean length at age of age-0 arrowtooth

flounder shifted 44 mm during this period, from 56&12 mm to lO(H11 mm. Age-l arrowtooth

flounder did not have a distinct mode, but the mean length at age increased by 35 mm during August to

November, from 163k25 mm to 19W22 mm. The mode of age-0 flathead sole shifted 10 mm from

August (30 - 34 mm) to November (40 - 45 mm), and the average length at age mcreased by 14 mm

from August (3%4 mm) to November (4Q9 mm). The mode of age-1 flathead sole increased 5 mm

(from 90 - 54 mm to 95 - 99 mm), but its mean length at age was also 14 mm larger in November

(11223 mm) than in August (9&15 mm). No mode shift could be followed for Pacific halibut, but

themeanlengthatageincreasedby38mmforage-0fish(~om71~l1mmto10~16mm)and30mm

for age-l fish (from 174510 mm to 204*5 mm). The 5 mm mode of age-l yellowfin sole increased by

20 mm from August (65 - 69 mm) to November (85 - 89 mm), and the mean length at age also

increased by 20 mm (from 72S mm to 9ti9 mm). The mode of age-0 rock sole increased by 20 mm,

from 35 - 39 mm in August to 55 - 59 mm in November, and the average length at age of age-0 rock

sole increased by 17 mm (from 41&7 mm to 5U16 mm). The mean length at age of age-l rock sole

increased by 3 1 mm (from IO%22 mm to 14cH20 mm). The mean length of age-l Alaska plaice

increased by 54 mm from August (163522 mm) to November (217*32 mm).

Length unalyse offlatfishes during June and August I994 (IU9401, ET9403 % lU9402)

Ages of flattishes captured during June (IU9401) and August (KI9403) 1994 within Chiniak

Bay, and flatfishes caught during August 1994 (KJ9402) within Kazakof Bay were estimated using

total length frequency plots (Table 9, Figures 8-10). Growth was estimated as the diflbrence between

length modes during June and August collections within Chiniak Bay. Age-l flathead sole grew 30

mm during this time, from 75 - 79 mm to 105 - 109 mm. Age-O halibut increased by 20 mm, from 35 -

39 mm to 55 - 59 mm. Age-0 yellowtin increased by 20 - 25 mm and passed a “biiday” between

June and August. Age-O yellowtin sole in June were 55 - 64 mm and the same group were age-l

duringAugust(80-84mm). AgeOrocksolegrew25mm,f?om15-19mmto40-44mm.

Platlishes caught during August were consistently larger at age within Chin& Bay (KW403)

than in Kazakof Bay (KJ9402). Age-O flathead sole were 35 - 39 mm in Chiniak Bay and 5 mm

smaller in KazakofBay (30 - 34 mm). Age-l f&head sole were 105 - 109 mm in Chiniak Bay and 15

mm smaller in Kazakof Bay (90 - 94 mm). Age 1 yellowfin sole were 20 mm larger in Chiniak Bay (80

- 84 mm) than in Kazakof Bay (60 - 64 mm). Both ages-0 and -1 rock sole were 5 mm larger in

Chin& Bay than in Kazakof Bay. Age-O rock sole were 40 - 44 mm in Chiniak Bay and 35 - 39 mm

inKazakofBay. Age-lrocksolewere115-119mminChiniakBayand110-113mminKazakof

Chiniak Bay/August 1993 (KI9301)

f%ysicd data within Chiniah Ruy/August 1993 (829301)

Temperature within Chiniak Buy/August 1993 (KI9301)

The general pattern for all bays was for warmer bottom water at shallow depths and cooler

water at deeper stations (Table 3, Figures 11-12). Deep central areas within bays and deep regions

outside bays had colder water than was found in shallow areas.

During KI9301, alI stations within Womens Bay (CS#l-5) had a thermocline in the upper 5

meters and warm bottom water (II.5 - 15.1°C). The warmest bottom water (15.l’C) examined

during KI9301 was at the head of Womens Bay in water ~5 m deep.

Stations near the head of Middle Bay (CS#16- 18) were usually isothermal. However, CS#27,

also at the head of Middle Bay, had a 0.5”C thermocline between 3 and 5 m water depth. Within outer

Middle Bay (CM l-15), temperatures either decreased gradually with increasing depth (CS#I I-15) or

thermoclines were present in the top 10 m and again in the bottom 20 m (CS#12-14). The outermost

station examined in Middle Bay (CS#15) had four distinct thermoclines: at 0 - 2 m, 5 - 10 m, 30 - 40

m and 60 - 75 m. Bottom temperatures in Middle Bay ranged from 8.3 to 108°C The coldest bottom

water examined during KI9301 (83°C) was outside the mouth of Middle Bay.

Stations near the head of Kalsii Bay (CS#19-23) were ftirly isothermal. Stations further out

the bay on the northern side (CS#24-26) and midbay (CS#6) had a thennocline in the upper 5 m.

Consecutive station ##6 had a second thermocline at 10 - 15 m. Temperature pro6les of the outermost

stations in JGtkin Bay (CS#7-10) all gradually decreased from the surface to depth. Bottom

temperatures in Kalsii Bay ranged from 8.9 to 10.7”C.

Salinity within Chinialc Bay/August I993 (IU9301)

When present, the haiocline was usually in the upper 5 m (Figure 13). In general, surface

salinity values were lower inside bays than outside. Conditions were usually isohaline in the mid to

outer bay. Bottom salinity of stations sampled during KI9301 was within a narrow range (Table 3,

Figure 14). Bottom salinity ranged from 29.2 to 32.4 PSU in Womens Bay, 3 I.1 to 31.8 PSU in

Middle Bay, and 3 1.1 to 32.1 in Kalsii Bay.

Substmte within Chiniak Bay/August I993 (KI9301)

Sites examined during KI9301 included the primary sediment types of gravel, sand and mud

(Table 10, Figures 15-20). All three primary sediments were collected in Middle and Kakin Bays, but

gravel was not collected in Womens Bay. The predominant sediment type within Chiniak Bay was

muddy sand, with pure sand at the head of both Middle and Kalsii Bays. Stations with >20% gravel

were only within Middle Bay.

Fiies within chiniak Bay/August 1993 (KI9301)

A total of 6646 fishes were entered in the database for use in CPUE (Table 11) distribution

and length analyses. A subsample of the captured fishes (87%, N=5809) fishes was measured of

which 3461 were t&fishes. The cumulative CPUE of flatlishes from 28 stations sampled during

KI9301 was 2,798, for an average CPUE of lO(H101 flatfishesktation duringKI9301.

Eleven species of flatfish were collected during KI9301. Lied in decreasing order of

abundance, the species composition (cumulative station CPUE of all ages) was flathead sole (N=1342),

63
rock sole (N=958), yellowfin sole (N=221), Pacific halibut (N=l29), arrowtooth flounder (N=69),

butter sole (N=39), Alaska plaice (N=l6), starry flounder (N=l I), English sole (X=8), Dover sole

(N=3), and sand sole (N=3).

Flatfishes were caught at all but two trawl stations during RI930 1. Rock sole were caught at

78% of stations sampled, flathead sole were caught at 52% of stations and halibut were caught at 48%

of stations. Both arrowtooth flounder and yellowfin sole were taken at 30% of stations, butter sole

were taken at 27% of stations and other flatfishes were collected at 11% of stations.

During August 1993 age-0 was the numerically dominant age class collected of a~~owtooth

flounder, Pacific halibut, rock sole, and English sole (Table 12). Age-l fishes were caught most oRen

of flathead sole, yellowfin sole, Alaska plaice and sand sole. Older specimens dominated the catch of

Dover sole, starry flounder and butter sole.

Multiple tows were collected at four stations using a 3.66 m beam and a 3.05 m beam. Catchper-unit-effort of flatihes using a 3.66 m beam was very sii to CPUE using a 3.05 m beam (Table

13).

Chiniak Bay/November 1993 (KI9302)

FLvh d&a within Chiniak Bay/November 1993 (KI9302)

No data on roundfishes were retained, and few data were retained for nonquantitative tows

during November 1993 within Chink& Bay (KI9302). Flatfishes were captured and measured

(‘W935) from each of the 10 stations with quantitative tows.

The cumulative flatfish CPUE Tom 10 stations during JSI9302 was 968, for an average CPUE

of 97*9 flat&he&u&on. Nme species of flaffish were wllected during KI9302 and are listed in

decreasing order of CPUE abundance (cumulative CPUE of all ages): rock sole (N=352), flathead sole

(N=306), yellowiin sole (N=140), arrowtooth flounder (N=130), Pacific halibut (N=lS), butter sole

(N=ll), Alaska plaice (N=5), Dover sole (N=3), starry flounder (N=2). During November 1993

(Table 14) catches of age-0 flatfishes were most prevalent for arrow-tooth flounder, flathead sole,

Pa&c haiibut and rock sole. Age-l fishes were most numerically dominant of Dover sole, yellowtin

sole and Alaska plaice. Age-22 fishes were captured most o&n of starry flounder and butter sole.

Chiniak Bay/June 1994 (KPMOI)

Fiih data within Chiniak Bay/June 1994 (lU9401)

A single quantitative tow at each of 12 stations was collected during June 1994 within Chin&

Bay (ID40 1). Flatfishes were captured at each station (Table 15), and all flatfIshes were measured.

The cumulative flat&h CPUE f?om 12 stations during KI9401 was 989, for an average CPUE

of 82~56 tlai5she&ation. The nine species of flatfish colkected during KJ9401 are listed in decreasing

order of CPUE abundance (cumulative CPUE of all ages): flathead sole (N=426), rock sole (N=354),

yellowfin sole (N=135), Par& halibut (N=55), butter sole (N=12), arrowtooth flounder (N=2), rex

sole (X=2), Alaska plaice (N=l) and sand sole (N=l). During June 1994 (Table 16), catches of age-0

fhrthshes were most Prevalent only for Pacific halibut, while age-l fishes were most numerically

dominant of rex sole, flathead sole and rock sole. Age-21 was numerically dominant of yellowfin sole.

Age-22 f&hes were captured most often of butter sole, Alaska plaice and sand sole. One age-0 and

one age-12 arrowtooth flounder were caught.

at a single station well within Kaisii Bay, in 50 - 60 m depth.

No age-12 rex sole were caught during KI9401.

Flathead sole (Figures 209-213)

A siigle age-0 was caught during KI9401 (8% of stations during KI9401,0.15=0.3 fish/tow).

This fish was caught at the head of Kaisin Bay, in <20 m depth.

Age-1 flathead sole (N=265) were caught at 58% of stations during KJ9401. The mean

number of age-1 f&h/tow was 22.1S7.7, and the largest catch was 114 fish/tow. Age-l flathead sole

were caught in Womens and Kalsin Bays, in depths 10 - 60 m. The highest abundances were well

within Kalsin Bay in depths 320 m, during high slack or ebb tide.

Chiniak Bay/August 1994 (KI9403)

Physical data within G’tiniuh Buy/August 1994 (Kl9403)

Temper&m within CMdak Buy/August 1994 (KI9403)

Bottom temperatures in Middle Bay ranged from 7.6 to 135°C (Table 6), the wide range of

bottom temperatures indicative of a relatively shallow bay. Bottom temperatures decreased with

increasing depth (Figures 244-245). Surface water temperatures in Middle Bay ranged from

approximately 10.5 to 15’C, also decreasing with increasing depth.

In Kalsii Bay, bottom temperatures ranged tiom 7.6 to 9.2”C. The fairly uniform distribution

of bottom temperatures in Kalsin Bay is indicative of a relatively deep bay. Kalsin Bay surf&

temperatures ranged from approximately 8.5 to 14°C. Unlike surface temperatures in Middle Bay,

stuface temperatures in Kalsm Bay did not decrease with increasing water depth. The coldest

temperatures were found at the head of the bay, indicative of cold freshwater input. Temperatures in

both Middle and Kalsm Bays were likely influenced not only by depth and location, but by tidal cycle

and solar heating.

Salinity within Cltiniuh Buy/August 1994 (IKI9403)

Middle Bay bottom salinities ranged from 29.8 to 32.1 PSU (Table 6, Figure 246-247) and

surface salinities ranged from approximately 25 to 32 PSU. Both bottom and surface salinities in

Middle Bay increased from the head to the mouth of the bay, corresponding with increasing depth.

The wide range of surface salinities, in particular, display the effects of f&h water input at the head of

the bay.

Kalsm Bay bottom salinities ranged from 3 1.7 to 3 1.9 PSU and surface salinities ranged from

approximately 30.5 to 3 1.7 PSU. The range of both bottom and surface salinities in Kalsin Bay were

small and the distribution was fairly uniform. Like tempemnxe, salinities in both Middle and K&in

Bays were likely influenced not only by depth and location, but by tidal cycle and solar heating.

Subs&&e within Chiniak Bay/August 1994 (K19403)

Combiions of sand muddy sand and sandy mud were found throughout Middle Bay (Table

17, Figures 248-254). Substrate at the head of Kaisin Bay was pure sand, shifting to muddy sand and

then sandy mud with increasmg depth down the central region of the bay toward the mouth. Outside

the mouths of Kalsm and Middle Bays, sand, muddy sand, sandy gravel and pure gravel were found.

Areas with gravel in sediment were examined only at and outside the mouths of the bays.

Ed data within Utiniuh Buy/August 1994 (XI9403)

A total of 10,659 fishes was captured during sampling in Chiniak Bay, August 1994 (Table

18). A subsample of 94% (10,034) of these fishes was measured. The cumulative CPUE of 12 fMish

species at 27 quantitative stations examined during August 1994 sampling in Chiniak Bay (KI9403)

was 4,486, for an average CPUE of 166rtl82 !&fishes/station. This was the highest average CPUE of

flatiishe&ation for ah 1993 and 1994 cruises, In addition, 208 flatfishes which were captured during

non-quantitative tows were included in the database for use in length analyses only.

Twelve species of flatfish were collected in KI9403. The species composition, listed in

decreasing order of CPUE abundance over aI stations was rock sole (2,461) flathead sole (901),

80
arrowtooth flounder (678) Paciftc halibut (284) yellowfin sole (76), butter sole (36), English sole

(29), starry flounder (7), sand sole (S), Alaska plaice (4), rex sole (3), and Dover sole (2).

During KI9403, age-0 was the numerically dominant age class collected of arrowtooth

flounder, rex sole, Pacific halibut, rock sole, and English sole (Table 19). Age- 1 fishes were caught

most often of flathead sole and yellowtin sole. Age-O and age-l were equally dominant age classes for

starry flounder. Older specimens (age-~2) dominated the catch of Dover sole, butter sole and sand

sole. Equal numbers of age-l and age-22 Alaska plaice were captured.

Habitats of juvenile (age-0 and age- 1) flatishes were analyzed to characterize nursery grounds

for flaffish of each species as described in the sections below.

Disriiibution ofjl$X%hes by age within Chiniak Bay/August 1994 (279403)

Arrowtooth flounder (Figures 254-266)

Age-O arrow-tooth flounder (N=663) were caught at 55.6% of stations during IU9403. The

mean number of age0 fish/tow was 12.3~i~32.4, and the largest catch was 157 fish/tow. Age0

arrowtooth flounder were found in water Tom 20 to 100 m deep, at 7.6 - 9.7”C and 3 1.7 - 32.1 PSU.

They were on all substrates sampled (sand, muddy sand, sandy mud, sandy gravel and gravel) and in all

regions (-2.5 to 6.5 km &om the mouth of the bay) except the shallow heads of bays. Seventy-five

percent of age-0 arrowtooth were in Middle Bay and 25% were in Kalsm Bay. Age-0 arrowtooth

slightly decreased in abundance relative to minutes atIer sunrise.

Age-l arrowtooth flounder (N=3) were caught at 11 .I% of stations during KI9403. The

mean nun&r of age-l fish/tow was O.lM.3, and the largest catch was two fish/tow. While age-l

arrowtooth flounder were not nearly as abundant as ag-0, their nursery characteristics were similar to

that of age-0 arrowtooth: 50 - 80 m, 7.6 - 8.4OC, 3 I .9 - 32.0 PSU, on sand or muddy sand substrate.

Unlike age-0 arrowtooth, age-l fish were found only outside the mouth of the bay (-1.8 to -2.4 corn

the bay mouth). Age1 arrowtooth were found only within the range of 160 - 280 minutes a&r sunrise

and, like age-O, over 75% were found in Middle Bay and less than 25% in Kalsin Bay.

Age-22 arrowtooth flounder were captured during KI9403 (N= 12).

Rex sole (Figures 25X,267-278)

Two age-0 rex sole were caught during a single tow at KI9403 CM1 1 Tow#l (corresponding

to 3.7% of stations). The mean number of age-0 fish/tow was 0.0i0.3. Age-O rex sole were found 6.1

km within IL&in Bay, between 30 and 40 m depth, at 8.3’C, 3 1.8 PSU, on muddy sand substrate.

A single age1 rex sole was caught at KI9403 CS#20 (corresponding to 3.7% of stations).

The mean number of age-l fish/tow was O.oM.l. The age-l rex sole was found -1.8 km from the

mouth of Middle Bay, between 60 and 70 m, at 7.6”C, 32.0 PSU, on muddy sand substrate.

Age-22 rex sole were not caught during KI9403.

87
Flathead sole (Figures 254,279-290)

Age-O flathead sole (N=358) were caught at 44.4% of stations during KI9403. The mean

number of age-0 fish/tow was 10.6a41.1, and the largest catch was 271 fish/tow. Age-O flathead sole

were found in waters 10 - 90 m, in increasing abundance to 55 m depth and in decreasing abundance

with further increasing depth. Age-O fish were found at 7 6 - 9.7”C and 31.8 - 32.1 PSU and from -2.4

to 6.5 km f?om the bay mouth. Age-O flathead sole were not found at the head of either Kalsin or

Middle Bay. Eighty-four percent of age-0 flathead sole were caught in Kalsii Bay. They were

associated only with mixed substrates, and were primarily over muddy sand and sandy mud substrates.

Fish abundances increased with increasing percent mud and decreasing percent sand, except for five

fish which were caught at a sandy gravel station in Middle Bay. Age-O flathead were found in

decreasing abundance with increasing time a&r sunrise. Although fewer samples were collected after

high tide than before, it appears that age-0 flathead were found in sharply increasing numbers up to 212

minutes before high tide and in decreasing numbers through slack high tide and after.

Age-l flathead sole (N=385) were caught at 44.4% of stations during KI9403. The mean

number of age-l fish/tow was 9.W24.5, and the largest catch was 135 fish/tow. Age-l flathead sole

were found in greater abundance than age-0 flathead. The distribution parameters of ages-0 and -1 fish

were nearly identical. Similar to age-0 fish, age-l flathead were distributed throughout bays (-2.4 to

7.7 km from the mouth of the bay) and were primarily (>80%) captured in Kalsii Bay. Age-l flathead

sole were found in 10 - 90 m water (highest abundance between 20 and 60 m), 7.6 - 9.7”C, 3 1.8 - 32.1

PSU. Abundances of age-l flathead sole paralleled the patterns discussed for age-0 flathead sole in

substrate usage and catch relative to sunrise and tidal stage.

Age-22 flathead sole were captured during KI9403 (N=158).

Pacific halibut (Figures 254,291-302)

Age-O Pacific halibut (N=282) were caught at 51.9% of stations during KI9403. The mean

number of age-0 fishitow was 20.3kl8.2, and the largest catch was 68 fish/tow. Age-O Pacific halibut

were found within Middle and Kalsin Bays and outside the mouth of Kalsin Bay. Age-O halibut were

only in depths under 50 m and were primarily ~30 m. While age-0 Pacilic halibut were found

throughout and outside the bay (-1.6 to 8.2 km from the bay mouth), most were at the heads of Kalsin

and Middle Bays. Age-0 halibut were at 8.2 - 13.5T, 29.8 - 32.0 PSU, and were captured over sand,

muddy sand and sandy mud substrates. Age-O halibut abundance increased with increasing percent

sand and decreasing percent mud. Age-O halibut were caught 261 minutes after sunrise and later.

The cumulative CPUE of age-l Pacific halibut caught during KI9403 was one fish,

corresponding to 3.7% of stations and 0.1M.4 fish/tow. Fish were captured at two stations, and the

largest catch was actually three fish/tow at CS#12, but due to the high number of replicates at this

station and an absence of age-1 halibut during other tows at CS#12, the averaged abundance for the

station was negligible (N=O. 18 fish). The presence of age- 1 Pacific halibut at CS#12 is noted at the

head of Kalsii Bay (Figure 291b). The other age-l halibut was found at CS#5 in Middle Bay, 2.4 to

7.7 km from the bay mouth, in 20 - 30 m, 8.2”C, 32.0 PSU, and on sand substrate.

One age-32 Pacific halibut was captured during KI9403.

Dover sole (Figure3 254,30%314)

No age-0 or age-l Dover sole were caught during KI9403.

Age-22 Dover sole were captured during KI9403 (N2).

88
Starry flounder (Figures 254,315326)

During KI9403 we captured three age-0 and three age-l stamy flounder, all in a siigle tow

(CM3 To&l) at the head of Middle Bay (corresponding to 3.7% of stations). The mean number

caught of each age was O.lH.4 fishitow. Starry flounder were captured in shallow (0 - 5 m),

nearshore waters, 7.5 km from the bay mouth, at 13S”C, 29.8 PSU, and onmuddy sand sediient.

A siigle age-22 staxy flounder was captured during IU9403.

Yellowfin sole (Figures 254,327-338)

Age-O (N=3) was the least abundant group of yeilowfm sole captured during KI9403. Age-O

yellowfin sole were caught at 7.4% of stations. The mean number of age-0 fish/tow was 0.11to.3, and

the largest catch was two iishltow. AU age-0 yellow-fin were captured outside the mouth of Kalsin Bay

(-0.7 to -1.6 km). The small number and size of age-0 yellowfin sole taken indicated that recruitment

was just starting. Age-O yellowfin sole were found in 20 - 50 m, 8.4 - 8.9“C, and 31.8 PSU. Age-O

yellowfin sole were captured on sand and gravel substrates.

Age-l yellow& sole (N=25) were caught at 22.2% of stations during KI9403. The mean

number of age-l fish/tow was 5.W.9 and the largest catch was 43 fish/tow. Due to the large number

of replicate tows at the station where this large catch was wUected, the calculated CPUE of the fish for

the station was only 16. Age-l yellowfin sole were found throughout and outside the bay (-0.7 to 8.2

km from the bay mouth), most were found closer to the head of the bay than age-0 yellowfin sole. AU

age-l yellowfin sole were wllected at depths less than 40 m and in waters 8.2 - 8.9OC and 3 1.7 - 32.0

PSU. Age-l fish were found only on sand and muddy sand substrate and were only naght 330

minutes after sunrise and later. Of the 25 age-l yellow-fin sole caught, 87% were from K&in Bay.

Age>2 yellowfin sole were caught during KI9403 (N=48).

Rock sole (Figures 254,339~350)

Rock sole was the most abundant species of flaffish captured during KI9403 (N of all

ages=2,461) and was also the most abundant age-0 fish caught (N=2,219). Age-O rock sole were

caught at 66.7% of stations. The mean number of age-0 fish/tow was 168.Wl94.5, and the largest

catch was 680 fish/tow. Eighty-one percent of age-0 rock sole were in Kalsin Bay and 21% were

caught in Middle Bay. Age-O rock sole were found throughout and outside the bay (-2.4 to 8.2 km

from the bay mouth) in depths up to 80 m, but were primarily wncentrated in water ~50 m. Age-0

rock sole were wllected in 7.6 - 9.9’C, 3 1.6 - 32. I PSU, and on all substrates sampled (sand, muddy

sand, sandy mud, sandy gravel, and gravel). Age-O rock sole abundances increased with increasing

percent of sand and decreasing percent of mud.

Age 1 rock sole (N=l83) were caught at 5 1.9% of stations during KI9403. The mean number

of age-l fish/tow was 8.7k9.8, and the largest catch was 36 fish/tow. The abundance of age-l rock

sole was spread fairy evenly throughout and outside Middle and K&in Bays (-1.8 to 8.1 km from the

bay mouth). The abundance of age-l rock sole was split fairly evenly between the two bays, 41% in

Middle Bay and 59% in Kalsii Bay. Age-l rock sole were found only in depths < 60 m, with highest

abundances between 20 and 50 m and decreasing abundance at shallower and greater depths. Age-l

rock sole were collected in 8.2 - 13.5”C waters and across the 111 range of sampled salinities (29.8 -

32.1 PSU). Lie age-0 fish, age-1 rock sole were on all substrates sampled (sand, muddy sand, sandy

mud, sandy gravel and gravel).

Age-22 rock sole were caught during KI9403 (N=59).

89
Butter sole (Figures X4,351-362)

Age-O butter sole (N=3) were caught at 14.8% of stations during KI9403. The mean number

of age-0 fish/tow was 0.2kO.7, and the largest catch was four fish/tow. The age-0 butter sole were

caught outside the mouth ofMiddle Bay (-0.8 to -2.4 km from the bay mouth). The presence of age-0

butter sole at two stations at the head of Kalsin Bay are noted (Figure 351a), but due to the high

number of replicate tows at these stations, the calculated CPUE of fish was negligible (hW.32 and

N=O.14 fish at CM6 and 12, respectively). Age-O butter sole were found in 5 - 80 m water depth, 7.6

- 9.l”C, and 3 1.7 - 32.1 PSU. They were found on sand, muddy sand. and sandy gravel substrate.

No age-l butter sole were caught during KI9403.

Age-22 butter sole were captured during K.I9403 (N=33).

Alaska plaice (Figures 254,36>374)

No age-0 Alaska plaice were caught during KI9403.

Two age-l plaice were captured at a single station during KI9403 (CS#3), corresponding to

3.7% of stations and an average of O.OkO.3 fish/tow. The plaice were at the head of Middle Bay, 7.5

km from the bay mouth. The fish were captured in 0 - 5 m water, at 13.YC, 29.8 PSU, and on muddy

sand sediment. This station had the lowest salinity and highest temperature of all the sites sampled

during KI9403

Two age-22 Alaska plaice were caught during KI9403.

Eirgiish sole (Figures 254,375386)

Age-O English sole (N=29) were caught at 22.2% of stations during KI9403. The mean

number of age-0 fish/tow was 1.3rt3.2, and the largest catch was 2 1 fish/tow. English sole were found

only near the heads of Middle and Kalsin Bays (7.5 - 8.2 km from the bay mouth). Eighty-one percent

of these fish were caught in a Single station (CS#3) in Middle Bay, the station with the lowest sahnity

and highest temperature of all the sites examined during KI9403. Age-O English sole were found in

<30 m water depth (primarily in 0 - 5 m), 8.2 - 13.5”C (primarily 13.5=‘(Z) and 29.8 - 31.9 PSU

(primarily 29.8 PSU). English sole were captured over sand and muddy sand substrates.

Age- 1 and age-22 English sole were not captured during KI9403.

Sand sole (Figures 254,387-398)

No age-0 sand sole were caught during KI9403.

A single age-l sand sole was found at the head of Kalsii Bay (CS#8), 8.2 km from the bay

mouth, corresponding to 3.7% of the stations sampled during KI9403. The mean number of age-1

fish/tow was 0.W. 1. The sand sole was caught in 0 - 5 m water, at 8.2OC, 31.9 PSU, and on sand

substrate.

Age-22 sand sole were captured during KI9403 (NTQ).

Kizakof Bay/August 1994 (KI9402)

ZVysid ainb within Kazukof Buy/August 1994 (K19402)

Temperature within K&f Bay/August 1994 (w9402)

Temperatures recorded from most stations within Kazakof Bay decreased gmdually from the

surface to about 15 m below the surf&e (Figure 399): Profiles usually encompassed a temperature

shift of several degrees within this depth range, and below 15 m depth, conditions were f&irly

isothermal.

Bottom temperatures in Kazakof Bay ranged from 4.4 to 14.2”C (Table 7, Figure 400). The

warmest bottom temperatures (9.4 - 14.2’C) were in shallow (<lo m), nearshore water. Bottom

temperatures decreased with increasing depth, and the coldest waters (4.4 - 5.O’C) were in water

deeper than 70 m.

5Winity within Kazakqf Bay/August 1994 (K19402)

Conditions within Kazakof Bay were usually isohaline, except for the surface 10 m (Figure

401). At CM9 & 18 a sharp variation in salinity occurred near the bottom. This feature was not

echoed within the temperature pro&s, but Smce these stations were in close proximity (0.5 km apart)

it is likely the salinity variation is not due to gear error.

Bottom salinities within Kazakof Bay ranged from 28.8 to 34.0 PSU (Table 7, Figure 402).

ID9402 SuW within K&f Bq/August 1994 (R19402)

Substrate at most stations appeared to be predominantly mud, but as sediment grain sii has

not yet been analyzed for this cruise, MEsh distribution was not described relative to substrate type.

Fii &a witSin Ka&ofBay/August 1994 (K19402)

A total of 645 fishes were enter& in the database from KI9402 for use in CPUE (Table 20),

distribution and length analyses. All captured fishes were measured, of which 217 (34%) were

flatfishes. The cumulative mean CPUE flat&h/station of flaffishes f?om quantitative tows at 29 stations

was 440, for an average CPUE of 15 flaUishe&ation during KI9402.

Five species of flatfish were collected during KI9402. Listed in decreasing order of abundance

(dative CPUE of all ages), these species were &head sole (N=275), yellow611 sole (N=l 1 l), rock

sole (N=47), Pacific halibut (N=I) and English sole (N=4).

Fla&&s were caught at all but 17% (N=5) trawl stations during IU9402. Flathead sole were

caught at 62% of stations, haliiut were caught at 3% of stations, yellowIin sole were caught at 21% of

stations, rock sole were caught at 28% of stations sampled, and English sole were caught at 3% of

stations.

During August 1994 within Kazakof Bay (Table 21), age-0 was the numerically dominant age

class mUmed of halibut, rock sole and English sole. Age-l fishes were caught most often of flathead

sole and yeUowfin sole.

Distribution offlatfishes by age within Kazakof Bay/August 1994 (K19402)

Flathead sole (Figures 403-409)

Age-U fiathead sole (N=85) were caught at 34% of stations during K19402. The mean number

of age-U fish/tow was 3.0±6.1, and the largest catch was 27 fish/tow. Age-0 fish were captured

primarily down the center of Kazakof Bay. They were caught in 20-90 m water depth and increased

in abundance with increasing depth. Age-0 flathead sole were not caught at the head of Kazakof Bay,

but were caught well within the bay, at sites 12 - 16 km from the mouth. They were captured only in

cool temperatures (4.7 - 7.7°C), and in salinities from 28.8 to 32.0 PSU.

Age-i fiathead sole (N=130) were caught at 48% of stations during K19402. The mean

number of age-I fish/tow was 4.2±6.2, and the largest catch was 21 fish/tow. Distribution of age-i

fish was similar to age-0 fish. Age-I flathead sole were caught in 20- 100 m water depth, and were

most abundant from 40 to 80 m water depth. Age-i fiathead sole were not caught at the head of the

bay. They were collected in waters of 4.6 - 7.9°C and 28.8 -32.1 PSU.

Age->2 fiathead sole were caught during 1(19402 (N60).

Pacific halibut (Figures 410-416)

Age-0 halibut (N=4) were caught at 3% of stations during K19402. The mean number of age0 fish/tow was 0. i±0.6, and the largest catch was four fish/tow. Age-U halibut were caught at a single

station near the head of Kazakof Bay, in 10-20 m water depth, 8.5°C, and 32.8 PSU.

No age-I or age-2 Pacific halibut were caught durmg K19402.

Yellowfln sole (Figures 417-423)

Age-U yellowfin sole were not captured during K19402.

Age-I yeilowfin sole (N=92) were caught at 17% of stations during K19402. The mean

number of age-i fish/tow was 2.6±10.9, and the largest catch was 60 fish/tow. Age-i yellowfin were

caught in 10-40 mwater depth, from 13 to 18km inbay, in 7.5-8.2°C and 31.3 -32.0 PSU water.

Age-?2 yellowfin sole were caught during K19402 (N19).

Rock sole (Figures 424-430)

Age-U rock sole (N=24) were caught at 17% of stations during K19402. The mean number of

age-U fish/tow was 0.9±2.6, and the largest catch was 12 fish/tow. Age-O fish were caught from 0 to

50 m water depth, 12 to 20 km inbay. They were caught within a wide range of temperatures (6.8 -

14.2°C). Age-U rock sole were caught in 30.5 - 32.0 PSU water salinity.

Age-I rock sole (N19) were caught at 17% of stations during K19402. The mean number of

age-i fish/tow was 0.6±2.2, and the largest catch was 12 fish/tow. Like age-U fish, age-I rock sole

were caught from 0 to 50 m water depth and 12 to 20 km inbay. Temperature ranges where age-I

rock sole were captured were slightly narrower (7.3 - 14.2) than for age-0 fish. Salinity of capture was

30.5 -34.0 PSU.

Age-?2 rock sole were caught during K19402 (N=5).

104
English sole (Figures 431-437)

Age-0 English sole (N=4) were caught at 3% of stations during K19402. The mean number of

age-O fish/tow was 0.3±1.0, and the largest catch was four fish/tow. English sole were captured at a

single station, in 0- 5 m water depth, at the head ofKazakof Bay in water of 14.2°C and 30.5 PSU.

Neither age-i nor age-?2 English sole were caught during K19402.

CONCLUSIONS

During prior funding, samples were collected in 1991 and 1992 within all major bays around

Kodiak Island. The 1991 and 1992 trawl samples and physical d2t formed the basis of the following

conceptual models of flatfish nursery habitat around Kodiak Island (Norcross et al. 1995A, 1995B).

Age-C rock sole are found predominantly in water depths less than 50 m on sand or mixed sand

substrate within 10 km of bay mouths. Age-C flathead sole are found predominantly in water depths

greater than 40 m on mud or mixed mud substrate throughout bays. Age-0 Pacific halibut are found

predominantly in water depths less than 40 m on mixed sand substrate near or outside mouths of bays.

Age-I yeliowfin sole are found predominantly in waxer depths less than 40 m on mixed substrate at

upper reaches of bays.

During 1991 and 1992, only age-O rock sole, flathead sole, Pacific halibut and age-i yellowfln

sole were captured in large enough numbers to form models. The conceptual models of flatfish

distribution (Noreross et al. 1995A, 1995B) based on 1991 - 1992 data were verified during collections

within Chiniak Bay during 1993 and 1994. As in 1991 - 1992, station locations were selected based on

depth and sediment strata, and data were analyzed using the physical parameters of location in the bay,

depth, bottom temperature, bottom salinity and sediment type. Data from M9403 suggests that

flathead sole are predominantly found in >20 m water depth, a modification from the >40 m mentioned

in the models.

In 1993 and 1994, age-i of flathead sole and rock sole and ages-C and I of arrowtooth

flounder were cptured in sufficiently large abundances for us to develop conceptual models of

distribution for additional age-groups and species. Age-I flathead sole were found in greatest

abundance in depths >20 m on sandy mud and muddy sand throughout the bay. Age-I rock sole were

mainly in depths <4Cm on sandy substrates throughout the bay. Both age-O and age-I anowtooth

flounder were found in water depth >20m on sandy mud and muddy sand near the bay mouth.

We found that our conceptual models of distnbution did not fit well in all seasons sampled.

However, since sampling was most extensive in August, we did not have sufficient data to develop

models for other seasons. This is a prime objective of a separately funded CMI project which is

cunently underway.

The four years of data now available on physical parameters and fiatfish abundances within

Chiniak Bay have enabled us to nanow the scope of future collections. In Chiniak Bay, we will sample

only at 'pennanent" stations which have been determined based on 1991 - 1994 data. Using these

"permanent" stations, we will develop indices of interannual abundance changes. In comparisons of

fish abundance and distribution from 1991 through 1994, differences among species and among

stations can be identified in addition to interannual variability. In particular, the distribution of rock

sole and flathead sole appear to be strongly related to depth and substrate type. In the future we will

examine depth and substrate patterns in more detail and will investigate other parameters which may

affect the distribution of the abundant flatfishes. From this, we will discern the key habitat

characteristics for each species, enabling us to monitor their abundances overtime.

ADDITIONAL PRODUCTS PRODUCED

Funding from Coastal Marine Institute assisted with analysis of 1991 fiatfish stomach contents

and with comparisons ofjuvenile fiatfish distribution from 1991 and 1992. Thus fhr, three manuscripts

based on these data have been accepted for publication and another has been submitted. All are

available upon request. The distribution and abundance of fiatfishes captured during August 1991 was

evaluated by linear discriniinant function analysis in the manuscript "Nurseiy area characteristics of

Pleuronectids in coastal Alaska, USA" (Norcross Ct al. 1995A), which has been accepted for

publication in the Netherlands Journal of Sea Research. Multivariare analysis of distribution and

abundance of fiatfishes captured during 1991 and 1992 was summarized in the manuscript, Habitat

models for juvenile Pleuronectids around Kodiak Island, Alaska, USA" (Norcross et al. 1995B).

Feeding diversity of juvenile fiatfishes was described in 'Diet diversity as a mechanism for partitioning

nursery grounds of Pleuronectids" (Holladay and Norcross 1995). These last two manuscripts were

presented orally at the International Symposium on North Pacific Flatfish, held 26 -28 October 1994 in

Anchorage, Alaska, and will be published in the unrefereed proceedings of that symposluim The

habitat model manuscript was submitted to Fisheiy Bulletin (JJS) and has since been revised based on

reviewers' comments. The information on diet diversity is the topic of Brenda Holladas M.S. thesis.

Additional sampling and analysis to develop indices of interannual fiatfish abundance is Sherri Dressel's

M.S. thesis.

Retated projects assisted through this funding

Live juvenile fiatfishes were captured during 1992 - 1994 field work for a separate lab study

(Moles et al. 1994, Moles and Norcross in press) to assess sediment preferences of various juvenile

flatfish species. The lab study addresses the response of flatfishes to various concelltldtions of

petroleum hydrocarbons in sediment, submits fishes to physiological tests which assess the effect of

non-avoidance of oiled sediment on the survivability of the fish, and also provides a monitor for rates of

growth, feeding, and respiration during long term (chronic) exposure to low levels of oiled sediments.

This research is Adam Moles Ph.D. thesis.

Appendix 2. Procedure for sediment analysis.

Part L Wet and dry sieving technique as modified from Folk (1980).

1. Homogenize sediment sample and obtain about 30 g (wet weight) subsample.

2. Add about 200 ml deionized water to subsample and stir.

Wet sieve with a 4 Phi (0.0625 mm) mesh sieve to separate graveL/sand from mud. Rinse sieve

contents with deionized water into a large evaporating dish until filtrate is clear. Remove any - large pieces of biomass. Do not remove shells from sample.

Pour filtrate into a pie-weighed 500 ml beaker. Rinse dish with deionized water and add rinsewater to beaker. -. 5. Dry beaker at 80°C for 12 hrs. Weigh beaker for mud fraction.

Use tap or deionized water to rinse sieve contents into a beaker and dry at 80°C for 12 hrs.

Allow beaker to equilibrate to room temperature. Dry sieve contents with -1.0 Phi (2.0 mm)

mesh sieve to separate gravel from sand. Use a brush to remove sediment sticking to beaker.

Remove large pieces of plant detritus. Weigh both fractions.

Part II. Loss on ignition (LOl)

Weigh crucible and 2-4 g (dry weight) of homogenized sediment sub-sample.

Cook crucible and sample at 500°C for 2 his.

Allow crucible and sample to equilibrate to room temperature, then record weight. Weight

loss during cooking at 500°C is organic content (organic LOl).

Cook crucible and sample at 850°C for 2 his.

Allow crucible and sample equilibrate to room temperature before weighing. Weight loss

during cooking at 850°C is carbonate content (carbonate LOl).
