Abstract

 The Resource Assessment and Conservation Engineering Division of the Alaska Fisheries 

Science Center conducts annual bottom trawl surveys to monitor the condition of the demersal fish 

and crab stocks of the eastern Bering Sea continental shelf. The standard study area encompasses 

a major portion of the eastern Bering Sea shelf between the 20-m and the 200-m isobaths and from 

the Alaska Peninsula north to approximately the latitude of St. Matthew Island (60°50'N). In 2009, 

two chartered trawlers, the 40-m FV Arcturus and the 40-m FV Aldebaran, surveyed this area. 

Demersal populations were sampled by trawling for 30 minutes at stations centered within 37.04 × 

37.04 km (20 × 20 nautical mile) grids covering the survey area. At each station, species 

composition of the catch was determined, and length distributions and age structure samples were 

collected from ecologically and commercially important species. 

 Three hundred seventy-six standard survey stations were sampled successfully. A total of 

94 species of fishes representing 21 families and 62 genera, as well as 168 species of invertebrates 

representing 13 phyla, were identified in the catches from the entire survey area. The combined 

biomass of walleye pollock (Theragra chalcogramma), yellowfin sole (Limanda aspera), and rock 

sole (Lepidopsetta spp.) was 5.6 million metric tons (t) which was 63% of the total fish biomass. 

The biomass of invertebrates was composed primarily of echinoderms (1.5 million t) and 

crustaceans (0.71 million t). 

Survey results presented in this report include abundance estimates for fishes and 

invertebrates, geographic distributions and size composition of the more common fish species, and 

contour plots of surface and bottom temperatures during the survey sampling period. Appendices 

provide station data, summarized catch data by station, species listings, and detailed analyses of 

abundance and biological data of the sampled populations.

Introduction 

 The eastern Bering Sea continental shelf supports one of the most productive groundfish 

and crab fisheries in the world (Bakkala 1993). Since 1970, groundfish such as walleye pollock 

(Theragra chalcogramma), yellowfin sole (Limanda aspera), and Pacific cod (Gadus

macrocephalus) have been the primary target species among commercial catches. Although 

many species of groundfish are caught commercially, walleye pollock is the most abundant with 

catches ranging from 0.8 million to 1.5 million metric tons (t) per year for the past 30 years, and 

marketed products represent 40% of the global whitefish market (Ianelli et al. 2008). 

Since 1971, the National Marine Fisheries Service (NMFS) Resource Assessment and 

Conservation Engineering (RACE) Division of the Alaska Fisheries Science Center (AFSC) has 

conducted an annual bottom trawl survey in the eastern Bering Sea to determine the distribution 

and abundance of groundfish and crab resources. 

The first large-scale survey of the eastern Bering Sea shelf was conducted in 1975 under 

contract from the U.S. Bureau of Land Management in response to a need for baseline data to 

assess the potential impact of proposed offshore oil exploration and development on fishery 

resources (Pereyra et al. 1976). During this baseline survey, sampling was conducted over the 

eastern Bering Sea shelf between the 20-m and 200-m isobaths from the Alaska Peninsula north 

to approximately 62°N. 

In subsequent years, the area coverage of the annual surveys was reduced until 1979 

when the most comprehensive survey of the Bering Sea shelf was undertaken in cooperation with 

the Japan Fisheries Agency (Bakkala and Wakabayashi 1985). That survey encompassed the 

entire region sampled in the 1975 baseline study plus the continental slope waters between 
St. Matthew and St. Lawrence Islands. A hydroacoustic survey was also conducted in 1979 to 

assess the midwater component of the walleye pollock population. 

Subsequent annual bottom trawl surveys have essentially resampled the stations 

established during the 1975 survey, with slight modifications each year. This region 

encompasses the major portion of economically important eastern Bering Sea groundfish and 

crab populations, except those primarily located in the deep continental slope waters. 

Commercial crab stocks managed by the Alaska Department of Fish and Game (ADF&G) are 

covered by the North Pacific Fishery Management Council’s (NPFMC) fishery management 

plan for the commercial king and Tanner crab fisheries in the Bering Sea and Aleutian Islands 

Regions. Crab species of interest include Tanner crab (Chionoecetes bairdi), snow crab (C. 

opilio), two stocks of blue king crab (Paralithodes platypus), red king crab (P. camtschaticus), 

and hair crab (Erimacrus isenbeckii). Detailed results from the analysis of crab data from this 

survey are available in Chilton et al. (2009). 

Begining in 1979 and on a triennial basis through 1991, the survey was extended to 

include bottom trawl sampling of the continental slope and in the region between St. Matthew 

and St. Lawrence Islands. After a hiatus from 1992 to 1999, the survey was resumed in 2000 as 

an independent bottom trawl survey series conducted on a biennial basis (Hoff and Britt 2009).

The groundfish information gathered by the annual biological surveys serves to 

1) provide annual fishery-independent estimates of abundance and biological condition of 

commercially exploited stocks to the NPFMC; 2) provide updates on the distribution and 

abundance information to commercial fishermen; and 3) continue a time-series database critical 

to our improved understanding of the population dynamics and interactions of groundfish 

species. This report presents information collected by the AFSC on the eastern Bering Sea shelf 

2
during the 2009 bottom trawl survey, which represents the twenty-eighth contribution to the time 

series. For results from the 2008 bottom trawl survey, please refer to Lauth and Acuna (2009). 

Methods 

Survey Area and Sampling Design 

The standardized eastern Bering Sea bottom trawl survey is based on a systematic design 

with a fixed sampling station at the center of each 37.04 × 37.04 km (20 × 20 nautical mile) grid 

square (Fig. 1). In areas surrounding St. Matthew and the Pribilof Islands, a high-density 

sampling of “corner stations” was implemented to better assess local blue king crab 

concentrations (Fig. 1). The original sampling design included 356 sampling stations that were 

sampled annually starting in 1982. Beginning in 1987, 20 additional stations in Strata 82 and 90 

were added to the survey (Fig. 2) to investigate the distribution and abundance of opilio crabs 

and the northern distribution of walleye pollock. All results reported herein include data 

analyses for all 376 stations combined. 

Sampling Logistics and Stratification Scheme 

Survey trawl sampling began in Bristol Bay and stations were sampled along alternate, 

longitudinal columns (Fig. 2). When possible, using two vessels, this pattern of sampling 

proceeded westward to the shelf edge. This practice was designed to balance the coverage of the 

survey area between vessels. The progression from east to west was established in response to 

movements by yellowfin sole and perhaps other species, which may be migrating eastward 

during the course of the survey (Smith and Bakkala 1982).

Figure 2. -- Sampled survey stations by vessel and the stratification scheme used for data analysis of the 2009 eastern Bering Sea

bottom trawl survey.

For catch analysis, the survey region was divided into six strata bounded by the 50-m, 

100-m, and 200-m isobaths, and into two geographic strata that separate the northwest and 

southeast portions of the study area (Fig. 2). This stratification scheme best reflects the 

differences observed in Bering Sea groundfish across the different oceanographic domains, and 

the intention of the design was to reduce the variances of population and biomass estimates 

(Bakkala 1993). Localized high-density sampling for blue king crab in Strata 30, 40, and 60 

necessitated a further subdivision into high-density and standard-density sample strata, resulting 

in a total of 12 strata. 

The overall sampling density for the entire survey area was one station per 1,322 km2

(Table 1). However, because of the high-density sampling in Strata 30, 40, and 60, and the 

irregular stratum boundaries, sampling density within the subdivided strata varied from one 

station per 775 km2

 (Stratum 42) to one per 1,721 km2 (Stratum 82). 

Survey Vessels and Sampling Gear 

 From 30 May to 28 July 2009, the survey was conducted aboard the chartered 

commercial stern-trawlers FV Arcturus and FV Aldebaran. All fishing operations were 

conducted in strict compliance to national and regional protocols detailed in Stauffer (2004). 

Both vessels were equipped with standard 83-112 Eastern otter trawls, which have 25.3-m (83 ft) 

headropes and 34.1-m (112 ft) footropes (Fig. 3). These nets were attached to tail chains with 

54.9-m (30-fathom) paired dandylines. Each lower dandyline had a 0.61-m chain extension 

connected to the lower wing edge to improve bottom-tending characteristics. Steel "V"-doors 

measuring 1.8 × 2.7 m and weighing 816 kg each were used.

Netmind net mensuration systems (Northstar Technical Inc., St. John’s, Newfoundland) 

were used aboard each vessel to monitor and record net height and width during fishing 

operations. Net width was measured as the distance between two sensors attached immediately 

forward of the connection of the upper breastline to the dandyline, and net height was measured 

from the headrope to the seafloor bottom. Estimates of mean net width were used in calculations 

of the area swept per tow (Rose and Walters 1990). For tows without observed net width values, 

a mean net width-inverse scope regression (Zar 1999) was used because it accounts for a 

majority of the variation for the eastern Bering Sea standard survey trawl (Rose and Walters 

1990; Fig. 4). 

Catch Sampling Procedures 

Detailed sampling procedures used in RACE eastern Bering Sea assessment surveys are 

described in detail by Wakabayashi et al. (1985) and Stauffer (2004). A brief summary of these 

procedures is described below. 

Samples were collected by trawling near the center of each grid square (or corner station, 

in the case of high-density strata) for a target fishing time of 30 minutes at a speed of 1.54 m/sec 

(3 knots). If the seafloor appeared to be untrawlable at the specified location, the nearest 

trawlable site within the same grid square was used. If the net was damaged or impacted by 

bottom structure during the trawl, the catch was discarded and a new sample obtained. 

Catches estimated to be less than approximately 1,150 kg (2,500 lb) were typically 

enumerated entirely, while larger catches were subsampled. After sorting the subsample, 

individual species were weighed in aggregate and counted, and these weights and numbers were 

expanded to the total catch. 

9
Fishes and invertebrates were identified and sorted to the lowest taxonomic level 

practicable. Similar morphological features between flathead sole (Hippoglossoides elassodon) 

and Bering flounder (H. robustus) make accurate identification of these species difficult in areas 

where the two species overlap; thus, in the analysis for this report these species are grouped by 

genus (Hippoglossoides spp.). Due to low abundance (believed to be < 1%) of southern rock 

sole (Lepidopsetta bilineata) and its morphological similarities to northern rock sole 

(L. polyxystra; Orr and Matarese 2000), these species were also grouped by genus (Lepidopsetta

spp.) for this report. 

Catch weights and numbers by species or species group were either estimated directly 

when subsampled, or estimated by extrapolating the proportion in the subsample to that of the 

entire catch weight. All Pacific halibut (Hippoglossus stenolepis), Greenland turbot 

(Reinhardtius hippoglossoides), skates, and commercial crab species were weighed and 

enumerated from each catch. Additional fish or invertebrate species (e.g., large sculpins, sharks, 

or octopus) were also completely sorted from the catch in some cases. 

Random samples of each fish species retained for length measurements were 

representative of the sex and size composition in the catch. The greater the size range of a fish 

species in the sample, the greater the number that were retained in the random subsample for 

length measurements by sex, up to a maximum of about 300 fish. Size composition data were 

collected for each commercially important groundfish species and many co-occurring species 

(Table 2). The sex of each fish from a sample was determined and then fish from the sample 

were measured to the nearest centimeter (fork or total length). Unless retained for sampling by 

the International Pacific Halibut Commission (IPHC) for management purposes, Pacific halibut 

10
were measured upon capture and immediately returned to the sea in an effort to reduce mortality; 

weights were estimated using an IPHC length-weight regression. 

Sagittal otoliths were collected from 13 fish species in both the northwestern and 

southeastern divisions of the survey area (Table 3). Three otolith pairs per sex centimeter 

interval per vessel (six pairs total) were collected for Pacific cod, Alaska plaice (Pleuronectes 

quadrituberculatus), arrowtooth flounder (Atheresthes stomias), northern rock sole, flathead 

sole, Greenland turbot, and yellow Irish lord (Hemilepidotus jordani). The great sculpin 

(Myoxocephalus polyacanthocephalus) was also collected at three otolith pairs per sex 

centimeter interval, but on only one vessel. Five otolith pairs per sex centimeter interval by 

vessel (10 pairs total) were collected for starry flounder (Platichthys stellatus) and yellowfin 

sole. Pacific halibut otoliths were collected aboard the FV Arcturus by the IPHC for population 

and growth analyses, and Alaska skate (Bathyraja parmifera) vertebrae were collected aboard 

the FV Aldebaran. For walley pollock otolith sampling, the eastern Bering Sea was divided into 

low- and high-density strata based on historical density data and a depth contour of 

approximately 70 m. Otoliths were collected from all hauls in which the total number of walleye 

pollock was 20 or more. Walleye pollock samples for otolith collection were selected at random 

from fish samples prior to sex determination. Six pairs of otoliths were collected in high-density 

strata and four in low-density strata. If walleye pollock length samples were stratified by size 

(i.e., separated into juveniles and adults before measuring), two of either the four or six otolith 

pairs were taken from juveniles. 

Individual fish weights were collected for all species for which age structures were taken. 

Otoliths for roundfish were preserved in 50% glycerol-thymol solution, and skate age structures 

(vertebrae) were frozen.

Surface and bottom water temperatures, as well as temperature and depth profiles, were 

recorded at 1-second intervals at each station using a Sea-Bird SBE-39 datalogger (Sea-Bird 

Electronics Inc., Bellevue, WA) attached to the headrope of the trawl. Depth to bottom was 

obtained by adding net height to headrope depth. 

Catch Data Analysis 

Trawl survey catch data were used to estimate 1) relative abundance; 2) population 

biomass; 3) population numbers, and 4) population abundance by size class. A brief description 

of the procedures used in the analysis of RACE Bering Sea survey data follows (for a detailed 

description see Wakabayashi et al. 1985). Note: some of the species collected were grouped by 

family for catch data analysis because of their limited commercial value or uncertain 

identification. 

Mean catch per unit effort (CPUE) values for each species were calculated in kilograms 

per hectare (1 ha = 10,000 m2) and number per hectare for each stratum; area swept (hectares) 

was computed as the distance towed multiplied by the mean net width (Alverson and Pereyra 

1969). Mean CPUE values were calculated for individual strata and for the overall survey area. 

Biomass and population estimates were derived for each stratum by multiplying the stratum 

mean CPUE by the stratum area. Stratum totals were then summed to produce estimates for each 

of the six main strata and the total survey area. 

For size composition estimates, the proportion of fish at each length interval (from 

subsamples at each station), weighted by CPUE (number of fish/ha), was expanded to the 

stratum population. Stratum estimates were summed to derive the estimated size composition for 

each of the six main strata and for the overall survey area. 

15
Except for Pacific halibut, otolith samples collected during the survey were read for age 

estimates by staff of the Age and Growth Program of the AFSC's Resource Ecology and 

Fisheries Management (REFM) Division. Age, growth, and population analyses will be 

presented in separate reports (e.g., Ianelli et al. 2008). 

Additional Research Projects 

 In addition to the survey operations, there were numerous research projects undertaken 

during 2009 (Table 4). Seven projects were collection requests for fish or crab specimens for 

educational outreach, reference material, and observer training. Projects conducted for the 

RACE Division included studies of 1) acoustic data collection for augmenting the midwater 

assessment of walleye pollock; 2) cooperative study with the Bering Sea Fisheries Research 

Foundation (BSFRF) to estimate the efficiency of the EBS survey trawl for snow crab; 

3) derelict crab pot habitat characterization at crab pot dump sites; 4) summer zooplankton 

biomass; 5) snailfish genetics and food habits; 6) snailfish visual ecology; 7) characterization of 

the benthic infauna community; 8) collection of in situ light intensity measurements; 9) visual 

monitoring for bitter crab and black mat syndromes; 10) reproductive potential of Bristol Bay red 

king crabs; and 11) Tanner crab genetics. The REFM Division special study projects included 1) 

trophic interactions and feeding ecology of commercial fishes (Table 5); 2) a short-tailed 

albatross survey; 3) shortraker rockfish genetics; 4) Alaska skate tagging, and 5) octopus 

specimen data. Projects from outside the AFSC included 1) halibut otolith, tag and size 

collections by the IPHC; 2) collection of biological and oceanographic data for the Bering Sea 

Integrated Ecosystem Research Program (BSIERP) and the Pacific Marine Environmental

Results and Discussion 

 A total of 376 stations were successfully sampled in 2009 (Fig. 2). Any hauls that 

sustained significant gear damage or contained debris such as discarded crab pots were 

resampled immediately following the unsucessful haul. Haul data for successfully trawled 

stations used in the analyses are listed in Appendix A along with the relevant information about 

each station, such as position, tow parameters (net width, depth, distance fished, and duration of 

haul), time, and environmental measurements (surface and gear temperatures) for each vessel. 

 After standard survey sampling was completed on 18 July, both vessels participated for 

6 days in the cooperative project with the BSFRF (see above), after which they returned to 

Bristol Bay to resample 32 stations for female red king crab (Fig. 2). It was necessary to 

resample the stations because the female red king crab had not yet molted and extruded their 

eggs when the stations were first sampled in early June. An accurate estimate of the abundance 

of molted and spawned female red king crab is critical to managers for determining if the red 

king crab population is overfished. 

Ocean Conditions 

 Sea surface temperatures recorded during the survey ranged from 1.1° to 7.3°C (Fig. 5). 

As in most previous surveys, surface temperature increased from east to west across the shelf. 

Sea bottom temperatures ranged from –1.7° to 6.3°C (Fig. 6) with warmer bottom temperatures

(> 3.0°C) occurring along the inner shelf from the northern portion of Bristol Bay to Nunivak 

Island, and on the outer shelf south of latitude 58°N. A cold pool, usually defined as an area 

with temperatures < 2°C, occupied most of the mid-shelf at depths between 50 and 100 m, and 

extended south to the Alaska Peninsula and into Bristol Bay. 

Average surface (4.7°C) and bottom (1.2°C) water temperatures were slightly higher than 

in 2008, but well below the long-term means from 1982 to 2008 for the surface (6.8°C) and for 

the bottom (2.4°C; Fig. 7). 

Relative Fishing Powers of Survey Vessels 

Historically, two vessels have been used to conduct the eastern Bering Sea shelf bottomtrawl survey, and fishing power corrections (FPC) have been applied when statistical differences 

of mean CPUE values were detected between the two vessels (Kappenman 1992). In 2006, 

application of an FPC was discontinued because of concerns that it was not correcting for vessel 

effect but was increasing the overall error in CPUE estimates. The underlying assumption for 

using an FPC was that one survey vessel was less efficient at sampling than the other survey 

vessel and that systematic error caused by vessel effects warranted correction (Munro 1998). 

Table 6 lists the calculated FPCs, by fish species, which were applied to CPUE estimates for the 

less-efficient survey vessel for survey years 1982-2005. Concerns about using an FPC were 

raised by studies showing that overall error in CPUE estimates can actually increase unless there 

are substantial differences between vessels (Munro 1998). Survey gear research done by the 

AFSC (Somerton and Weinberg 2001, Weinberg 2003, Kotwicki and Weinberg 2005, Kotwicki 

et al. 2006, Weinberg and Somerton 2006, Weinberg and Kotwicki 2007), and real-time 

monitoring and data collection of trawl and vessel performance (Zimmerman et al. 2003), has

increased awareness and helped reduce possible systematic errors associated with “vessel 

effects”. 

One reason why the overall error of FPC-adjusted CPUE estimates was probably 

artificially high was nonrandom selection of stations from alternate columns for calculating the 

FPC. Without random selection of stations, it is possible that observed differences between 

vessels are actually real differences in fish distribution and abundance. For example, the location 

and timing of the cold pool on the eastern Bering Sea shelf has a dramatic effect on fish 

distribution, so if one vessel is sampling a column inside the cold pool and the other is sampling 

in the adjacent column outside the cold pool, differences in catch rates between the two vessels 

may be due to the effect of the cold pool on fish distribution rather than a vessel-effect. 

The RACE Groundfish Assessment Program is continuing to investigate sources of 

systematic error and to devise methods for minimizing systematic error in area-swept 

calculations (Stan Kotwicki, AFSC; personal communication). Before these new methods can be 

implemented, it will be necessary to reconcile historical data and complete the development of a 

new relational database for accessing stream data for doing area-swept calculations. Until this 

can be accomplished, application of an FPC adjustment will not be done; however, so as not to 

affect the historical time series, FPC adjustments made to catches prior to 2006 will remain 

unchanged. 

Relative Abundance

 The relative abundance of the 11 most abundant fishes are presented in Figure 8. These 

taxa accounted for 66% (160 kg/ha) of total catch mean CPUE (240 kg/ha) and 93% of total fish 

mean CPUE (172 kg/ha). The walleye pollock mean CPUE for all areas combined was

46.1 kg/ha. Walleye pollock was the dominant groundfish species at depths between 50 and 200 m. 

This species was encountered at nearly all sampling stations, with the largest mean catches 

observed in the outer shelf stations. Pacific cod catch rates were at similar levels across all three 

depth zones with an overall mean CPUE of 8.7 kg/ha. Rock sole, as well as yellowfin sole, with 

overall mean catch rates of 31.1 and 35.1 kg/ha, respectively, were abundant in water depths less 

than 100 m. See Appendix B for a descending rank of all organisms caught. 

Biomass, Abundance, Distribution, CPUE, and Size Composition of Principal Species and 

Species Groups 

A total of 94 species of fishes representing 21 families and 62 genera were identified in 

the catches from the entire survey area (Appendix C1). In addition, a total of 266 individual 

invertebrate taxa were identified from 13 phyla, with 168 identified to the species level 

(Appendix C2). 

Total demersal animal biomass for the standard survey area was estimated at 

12.1 million t, of which fish species accounted for 72% (8.8 million t; Table 7) and invertebrates 

28% (3.3 million t; Table 8). The greatest concentrations of fish biomass were located in Bristol 

Bay, along the Alaska Peninsula, around the Pribilof Islands, and in the outer shelf northwest of 

the Pribilof Islands (Fig. 9). The fish biomass was dominated by pleuronectids (5.5 million t) 

and gadids (2.7 million t; Table 7). The biomass of invertebrates was composed primarily of 

echinoderms (1.5 million t) and crustaceans (0.71 million t; Table 8). 

Geographic distributions, population numbers, biomass estimates, and size composition 

are presented in Figures 9-48 and Tables 9-28 for each of the following eastern Bering Sea 

groundfish: walleye pollock, Pacific cod, yellowfin sole, northern and southern rock sole

histograms relating the population percentage by 1-cm length interval for each stratum and in 

population numbers for the total survey area. Catch per unit effort (CPUE), population, and 

biomass estimates and associated variances and confidence limits are listed for each species by 

stratum. All results except size composition are presented for sturgeon poacher (Podothecus

papilio), eulachon (Thaleichthys pacificus), capelin (Mallotus villosus), Pacific herring (Clupea

pallasi), and Arctic cod (Boreogadus saida) in Figures 49-56 and Tables 29-35. 

Appendices to this report contain detailed results of the survey including population 

estimates by sex and size class, and rank of fish and invertebrate taxa by weighted total CPUE 

(kg/ha). A more detailed explanation of results follows for the 10 fish species (or grouped 

species) that are commercially exploited on the eastern Bering Sea shelf. 

Summary of results for commercially exploited groundfish species 

Walleye Pollock (Theragra chalcogramma) 

Walleye pollock were captured at 92% of the standard survey stations (Fig. 10). Catch 

rates were lower on the inner and middle shelf compared to the outer shelf. The highest densities 

31
were north of the Alaska Peninsula, around the Pribilof Islands, and along the northwest outer 

shelf west of St. Matthew Island (Fig. 10). The total biomass and abundance of walleye pollock 

for the entire survey area was 2.28 million t and 3.46 billion fish with an average weight per 

walleye pollock of 0.66 kg (Tables 10a and 10b) and average length of 38.64 cm (Fig. 11). The 

2009 biomass estimate was 25% lower than the 2008 estimate of 3.03 million t. Besides general 

year-class variability, relatively lower estimates may in part be due to a shift of the population to 

the shelf edge or a change in the vertical distribution pattern of pollock caused by the colder than 

average water temperatures on the Bering Sea shelf (Ianelli et al. 2008, Kotwicki et al. 2005). 

One-year-olds, represented by the modal length of 10-15 cm, had the highest relative abundance 

on the inner and middle shelf compared to the outer shelf, where larger pollock had higher 

relative abundance (Fig. 11). The mode for the population of 1-year-olds peaked at about 150 

million in 2009, compared to a little over 100 million in 2008, and 400 million in 2007. Age-2 

and age-3 pollock (length range of 15-35 cm) are generally underrepresented in survey trawl 

catches; however, modes for both year classes can be seen in the plot of population abundance at 

length (Fig. 11). 

Pacific Cod (Gadus macrocephalus)

Like walleye pollock, Pacific cod were broadly distributed across the shelf, being 

observed in 96% of the trawls (Fig. 12). The 2009 biomass was 0.43 million t which was the 

same as 2008; however, population numbers increased by 47% to 0.72 billion due to the 

prevalence of several smaller year classes (Fig. 13). Several length modes < 50 cm were evident, 

suggesting strong 2006-2008 year classes (Fig. 13). The highest catch rates of Pacific cod were 

32
observed in the middle and outer shelf, especially between St. Matthew Island and the Pribilof 

Islands and north of the Alaska Peninsula (Tables 10a and 10b; Fig. 12). 

 

Yellowfin Sole (Limanda aspera)

Yellowfin sole catch rates were highest on the inner shelf and decreased to little or 

nothing on the outer middle shelf, except in the vicinity of St. Matthew Island and the Pribilof 

Islands (Tables 11a and 11b; Fig. 14). From 2008 to 2009, the biomass decreased from 2.1 to 

1.7 million t and the population size decreased slightly from 8.9 billion to 8.4 billion. Smallersized yellowfin sole < 20 cm were only found on the inner shelf, with larger sizes up to 40 cm 

inhabiting both the inner and middle shelf (Fig. 15). Yellowfin sole undergo a spring migration 

from the shelf-slope break onto the inner shelf each year for spawning and feeding, and there are 

higher proportions of male yellowfin sole with decreasing depth (Nichol 1998). The group of 

smaller yellowfin sole on the inner shelf probably represent the juveniles less than 6 years of age 

that overwinter in the nearshore (Nichol 1997). 

 

Northern and Southern Rock Sole (Lepidopsetta spp.)

The highest concentrations of rock sole were found around the Pribilof Islands and in the 

inner middle shelf in the southeastern half of the EBS (Tables 12a and 12b; Fig. 16). Estimated 

biomass decreased by 24% from 2008 to 1.74 million t and estimated population numbers 

decreased by 22% to 8.2 billion (Tables 12a and 12b). Size increased with increasing depth (Fig. 

17). Spawning and feeding migrations for rock soles are poorly understood, but in general they 

migrate from relatively shallow feeding grounds in the summer to deeper spawning grounds in 

the winter (Fadeev 1965, Shubnikov and Lisovenko 1964).

33
Flathead Sole and Bering Flounder (Hippoglossoides spp.)

Although age structures were taken for each of the two Hippoglossoides species, they 

were combined in the presentation of results because they are managed as a two-species complex 

by the NPFMC (Stockhausen et al. 2008) and it facilitates comparisons with previous surveys. 

Bering flounder are typically more arctic in their distribution compared to flathead sole, which is 

generally distributed in the southeastern half of the shelf. The combined “flathead sole” were 

distributed on the middle and outer eastern Bering Sea shelf. The highest CPUEs were in the 

northwest outer shelf, near the Pribilof Islands, and in the southern middle shelf region (Tables 

13a and 13b; Fig. 18). Estimated biomass (0.42 million t) and population number (1.4 billion) 

were about a 25% decrease from 2008 (Tables 12a and 12b). A similar size range of flathead 

sole (10-50 cm) was observed across the entire shelf (Fig. 19). 

Alaska Plaice (Pleuronectes quadrituberculatus) 

Alaska plaice was most abundant on the inner and middle shelf in waters < 100 m, with 

the highest concentrations bordering the 50 m contour (Fig. 20). From 2008 to 2009, the 

estimated biomass increased slightly from 0.51 million t to 0.53 million t, and the population 

increased from 0.94 billion to 1.02 billion (Tables 14a and 14b). The increase in population was 

due to increased numbers of plaice in the 25-40 cm size range. The size range was from 15-60 

cm with smaller sizes of Alaska plaice (< 20 cm) only occurring at depths < 50 m (Fig. 21). 

34
Greenland Turbot (Reinhardtius hippoglossoides) 

Greenland turbot typically inhabit the upper continental slope, although juveniles may 

spend several years on the continental shelf before moving to deeper water (Alton et al. 1988). 

Greenland turbot were captured at 28% of the survey stations with all but a few found in the 

northwest part of the middle and outer shelf (Fig. 22). Biomass estimates decreased for the sixth 

consecutive year from 31,700 t in 2003 to 11,000 t in 2009 (Table 15a); however, the estimated 

population number increased from 15.3 million in 2008 to 22.5 million in 2009 and was 48% 

higher than the 6 year mean of 15.2 million (Tables 15a and 15b) due to a high abundance of 

10-15 cm juveniles (Fig. 23). 

Arrowtooth Flounder (Atheresthes stomias) 

Arrowtooth flounder were observed all along the outer shelf with a patchy distribution in 

the middle and inner shelf (Fig. 24), and they ranged in size from 8 to 75 cm (Fig. 25). Catch 

rates were generally higher at the deeper, more southern stations, with few found in strata along 

the inner shelf and northern middle shelf (Tables 16a and 16b; Fig. 24). Estimates of both 

biomass and population size decreased from 2009 to 2008; biomass decreased from 0.53 million 

to 0.41 million t and population from 1.2 billion to 0.9 billion (Tables 16a and 16b). 

Kamchatka Flounder (Atheresthes evermanni) 

Kamchatka flounder were mostly observed around the Pribilof Islands and along the 

northwestern outer shelf with the highest catch rates and largest mean size occurring in the 

northwest (Figs. 26 and 27). From 2008 to 2009, the biomass decreased from 58,000 to 50,000 t 

and the population decreased from 120 million to 84 million fish (Tables 17a and 17b). 

35
Pacific Halibut (Hippoglossus stenolepis) 

Pacific halibut were widely distributed across the shelf and captured at 79% of the 

stations with decreasing catches farther north (Fig. 28). The estimated biomass increased 

slightly from 140 thousand t in 2008 to 169 thousand t in 2009 and the population decreased 

from 108 million to 102 million in the same time period. A broad size range of halibut was 

distributed across the entire shelf (Fig. 29).

Acknowledgments 

Recognition and appreciation is extended to the captains and crew of the FV Aldebaran

and FV Arcturus. Without their expertise, goodwill, and sacrifice, this survey would not be 

possible. Thank you to the Trident Corporation for making the vessels available and always 

maintaining safety as a top priority. Great appreciation is also extended to all the scientists, 

researchers, and interns who worked tirelessly aboard each vessel to complete the survey in a 

safe and successful manner. We also thank the survey support team who provided us with 

technical and scientific equipment. Finally, appreciation is extended to the reviewers of this 

document whose excellent comments and suggestions greatly improved it.

Appendix A: Station Data, 2009 Eastern Bering Sea Trawl Survey

Appendix A contains station data by vessel for the 376 successfully completed standard 

survey stations. In using the tables, the following should be noted: 

1. Time represents the nearest hour and minute at the start of the haul. 

2. Haul numbers are not always sequential because unsatisfactory hauls were omitted. 

3. All longitudes are in the Western Hemisphere and latitudes in the Northern 

Hemisphere. Starting and ending positions for each haul are displayed as degrees and 

decimal minutes. 

4. Net measured codes are as follows: 

 Y = Net width was measured by net mensuration gear. 

 N = Net width was estimated from a function of wire out or wire out. 

5. Catch weights are displayed in total kilograms
