'!he year 1990wasthe 14th year of observer coverage of foreign f~

vessels as IIlal'X2tedby the MagrrosonFishery CanseJ:vationam ManagementAct

(MFCMA) of 1976. Foreign vessels ergaginJ in iniepen1ent f~ operations

or actin:J as processors of grourrlfish caught by U.S. fisherman (joint venture)

were required to have a U.S. fisheries observer aboard. '!he observers'

objectives were to 1) collect data used to estimate the cammercial catches,

2) detennine the incidental catches of marine ~11'II'I1rIl s am species whose

retention is p:rchibited by U.S. regulations, 3) provide information ~E'd to

assess the biological status of the various stocks of fish, am 4) report p::ssible violations of U.S. f~ regulations.

'!his report summarizesthe 1990observer sanplinJ data collected aboard

foreign ves.~l!'; operatinJ within the U.S. 20o-mile Exclusive EconcmicZone

(EEZ)of the northeast Pacific Oceanam eastern BerinJ Sea. A description of

vessel types am a li.stirg of vessel-class abbreviations used in this paper's tables are presented in Table 1. ObseJ:versdJtained information on the

location, duration, average depth, am catd1 weight of each trawl haul made

while they were on board. '!hey sanpled several hauls each day to detennine

After the inception of the MFCMA in 1976, foreign f~ fleets continued

to daninate grourrlfish fisheries in U.S waters as they had since the 1960s.

azt, in 1986, joint venture fisheries had ~ the daninant fishay, am in

1989, U.S. danestic fisheries had grownto p~, havinJ campletely eliminated foreign f~ am nearly havinJ displaced joint venture

fisheries. In 1990, no grourrlfish :rescAJrCeSwere allotted for foreign f~, am joint venture fisheries :received grourrlfish allocations in only

two major regions: the BerinJ Sea-Aleutian !slams region am the Washi.rgton- Oregon-Califomia coast.

'!he sanplinJ procedures used by abservers in 1990have been described by Nelson et ale (1981) am Frenc:het ale (1981). While on the vessel, observers

detenni.ned the species \.A.U~ition of the catd1 by ~ representative basket sanples of various delivered hauls. Individuals of each species in the

sanples were then cowrt:edam weighed. If the catd1 delivered to a joint

venture prcx:::essinJship was O.JII'l<lSedof a high percentage of one species, the

abserver often detenni.ned the C:I XIII xJ6ition of the entire haul by separatinJ,

~, am weighinJ all nontarget species. '!he weight of the target species catd1 was calculated by subtractin:J the weight of the other species fran the total haul weight. '!he mnnbersof the target species were dJtained

by dividinJ the total weight of the species catd1 by the average TNeightper fish, determined fran a sanple of the catd1. For those species for which

additional biological information was desired, lergt:h frequencies were taken

In this tedmique, the average daily catch rates of each species by vessel

class (cbtained by observers an the VE'S"'=P 1~ sanpled) for a particular statistical reporti.rg area were cq::pliedto the total numberof vessel days an

order to provide a ''best estimate" of the catch, the u.s. catch estimates were

used Wen observer coverage of a week-area-vessel class element was at least

20%an:i Wen the U.S. estimate of the catch differed by I1X)rethan 10%from the

vessel-reported catch for that element. Whenthose elements did not meet

either of the above criteria, catches reported by foreign processors were used.

Estimates of Joint Venture Incidental Catches and Average Weights of Pacific Salm:m,Pacific Halibut,

Snow(Tanner) Crabs, and KingCrabs

Obsel:verdata provided the follCMllg catch estimates for each of the

four prohibited species: 1) the meanincidence or the average numberof

irxlividuals caught per metric ton (t) of groundfish catch; 2) the total mnnber

of irxlividuals caught; 3) the total weight of the catch. '!he average number

per metric ton and the total numberof irxlividuals caught were estimated by ImIltiplying the average weekly incidence rates for each nation, statistical

reporting area, and vessel class by the estimated weekly groundfish catches

for those samenations, areas, and vessel classes. The total catch weight was

calculated by ImIltiplying the estimated numbersof fish or crab caught each

nonth by the average weight per irxlividual in kilograms, this being detenni.ned

from observer samples.

Estimates of Rockfish and Flatfish Catch by Species

'!he joint venture catches of irxlividual rockfish and flatfish species

were estimated by applying the meanannual species percentages by weight, conputed.from species composition data collected by U.S. observers, to the

total rockfish and flatfish catch. In the Bering Sea, no rockfish were

reported taken and because specific catch allocations were set for ye1.lCMfin sole (Pleuronectes asoor), rock sole (P. bilineatus), and Greenland turbot

(Reinhardtius hipPOCJlossoides)in this area, actual catch estimates have

already been madefor these species. Specific allocations were also set for

Pacific ocean perch (Sebastes alutus) in the Washington-oregon-Califomia region. It should be noted that even though all observers were trained in

species identification and instructed in the use of fish identification keys,

errors in the identification of sane species could have been made, am. any

errors would affect the irxlividual species estimates.

Area of Samplirg

'!he area sanpled by observers in the eastern Berirg Sea lies within the

zones defined by the North Pacific Fishery ManagenEl1tCouncil's (NPFMC) Berirg Sea groorrlfish Fishery ManagenEl1tPlan (FMP), Anen:E1entl2A (Fig. 1). Zones

1, 2, ani 3 are designated in the FMP protectirg crab ani Pacific halibut

stcx::ks. '1hese three zones are further divided into areas: Zone 1 = Areas

511, 512, ani 516; Zone2 = Areas 513, 517, ani 521; ani Zone3 = Areas 514,

515, 522, 530, ani 540. Additionally, Area 517 is also designated as Zone 2H.

Catdl Allocations

For 1990, the danestic annual harvest (DAH),which consists of danestic

annual processirg (DAP-the total annmt of groorrlfish expected to be caught in fully u.s. groorrlfish fisheries) ani joint venture processirg (JVP-the total annmt of groorrlfish allotted to be caught in joint venture groorrlfish operations), was again expected to acx::ountfor the entire 2 million t allowed

to be taken in the Berirg Sea ani Aleutian Islams region, resultirg in no

allocation for foreign fishirg. '!he joint venture allotment was 252,382 t, while the dcmastic fisheries :received an initial allocation of 1,495,320 t,

ani a :reseJ::Veof 252,298 t was set aside.

For the sec::arrlconsecutive year, in:::reases of allotments given to fully U.S. dcmastic operations resulted in greatly rron~ allocations for the joint

venture fishery ani limited it to targetirg on only yellowfin sole, rcck sole, ani the "other flourrlers" category (pr:iJnarily flathead sole (HiPPOCflossoides

elassodon) ani Alaska plaice (Pleuronectes auadrituberculatus). Joint

venture allotments for 1990were less than the 1989 cnoountsby 90%for Pacific

cod (Gadusmacrocephalus), 53%for rcck sole, 26%for "other" flourrlers, ani

5%for yellowfin sole; ani, for the first time in the history of the joint

venture fishery, walleye pollock ('lberaqra d1alccx:rrarnma) was not an allowable

target species, resultirg in an allocation 93%less than in 1989. As:recently

as 1988, the joint venture fishery was allocated over 1 million t of walleye pollock.

Obse1:verCoverageof Fishirg Fleets

Estimates of U.S. Joint Venture GrolIrrlfishCatches

DJe to attainment of bycatch quotas (di~ later in the Restrictions

section of this report), U.S. fi.shin;;Jvessels delivered only 53%(or 133,438 t

of grourxifish) to foreign process:in] vessels in 1990 (Table 3). YellCMfin

sole wasthe major species or species group taken, c:xxrpris:in]52.2% (or 69,677 t) of the joint venture catch. Walleye pollock, taken only as bycatch, c:xxrprisedthe secorx:llargest am:JU11t of catch (16.8%or 22,397 t). other

species taken in substantial am:xmtswere "other" flatfishes (14.0%or

18,748 t), rcx:::ksole (7.9%or 10,492 t), am Pacific c:cxi(6.5%or 8,078 t).

Estimated foreign am joint venture catches are sununarizedby species fran 1977 through 1990 in Table 4. 'Ihe 1990 joint venture grourxifish catch

:represented the lowest total since 1982. 'Ihe canbined foreign am joint

venture catch was the lowest since the inception of the~, less by 400,000 t than in 1989, am less by over 1 million t than the next lowest

total, which wastaken in 1979.

'Ihe distribution of the joint venture grourxifish catch is presented by

area in Figure 2. Areas in Zone2 contributed 62%(Area 513-41% am Area

areas in Zone3 acca.mted for 3%(Area 514-3% am Area 515-0.000004%).

Restrictions

In 1987, Amen::hta1t10 to the NPFMC'sBer:in] Sea grourxifish FMPwas

enacted to UJuLL-ulthe incidental catches of red kin:.1 crab (Paralithodes camtsd1aticus) am Chionoecetes baircli dur:in] yellCMfin sole am other

flatfish fisheries am to protect the stocks of these two crab species fran

further decline. Whenthis amerrlIoontexpired at the ern of 1988, eoorgency :regulations were i11p)S€dto control the bycatch of these species in foreign, joint venture, am danestic fisheries until the inplemntation of Amen::hta1t

12Ain August 1989. Restrictions retained fran Amen::hta1t10 by Amen::hta1t12A

are 1) the prohibition of foreign am joint venture trawl:in] in Area 512,

between larg. 160° am 162°Wam scut:h of lat. 58°N; 2) the :reservation of the

south.em portion of this area for a COlrtrolled~ic trawl fishery for

Pacific c:cxi;am 3) the designation of zones that can be closed to a fishe:ry wheneverits particular bycatch limits are attained (Fig. 1). Amen::hta1t12A

also established limits on the bycatch of Pacific halibut, creat:in] primary

am secorrlary bycatch quotas. Pacific halibut catches are annulated over the

entire Ber:in] Sea region, am the attainment of the primary quota closes Zones

1 am 2H, while attainment of the secorrlary quota closes the entire Ber:in] Sea

am Aleutian Islarxis region.

For 1990, the joint venture yellCMfin sole-flatfish fishe:ry received

bycatch limits of 50,000 red kin:.1 crab in Zone 1, 400,000 ~ baircli in Zone 1,

am 1,000,000 C. baircli in Zone2; for Pacific halibut, the fishery received a

primary quota of 660 t am a secorrlary quota of 800 t. All joint venture

fishe:ry closures in 1990 ocx:::urredas a result of attainment of these bycatch

quotas (Fig. 3). 'Ihe first closure occurred on 25 January. However,due to a

last-minute rise in bycatch rates alarg with the arrival en ~~ of the

Beri.rg Sea was closed on 5 Mardl, with an estiInated Pacific halibut bycatch of

776.3 t. art, at the request of the joint venture fishiI'g irrlustry, operations resumedon 24 June in the BeriIg Sea, with a re.mainin;Jhalibut

bycatdllimit of 23.7 t am with fi.shirq limited to Togiak Bay in Area 514

(wherebycatdl rates of halibut have been low in past years). Higher-than- expected halibut bycatdl rates, however, closed the fishery within 7 days with

a final seoorrlary bycatdl estiInate of 798.5 t, am on 1 July the BeriIg Sea

517 (between 12 ani 64 crabs/t for all nations, bIt IOOStly30-40 crabs/t).

Except for Area 514, the incidental catdl rates for snow (Tanner) crabs in the

1990 joint venture fishery greatly exceeded those of the 1989 fishery for

every area am nation. As mentioned earlier, fishin:J oocurred in all areas

durin:J in the first quarter of 1990 except for Area 514. In 1989, nnst of the

Unalaska Islam in Area 515. For the brief fishery in Togiak Baythat

overlawed the sec::onjam third quarter, no Sf'ON (Tanner) crabs were caught

except in one blcx::k(lat. 58°Nam lOn:J. 159°W)Were the rate was less than

SUMMARY OF OBSERVER SAMPLING OFF '!HE CDASTS OF

WASHING:roN, OREX;ON, AND CALIR>RNIA

catch Allocations

'!he joint venture fishery for Pacific whitin:J (Mgt:lucciusproductus) received a quota of 171,000 t in 1990. For the secon:i year in a rr::M, the

foreign fishery did not receive an allocation am did not fish.

In the Pacific whitinJ joint venture fishery, quotas are only set for

Pacific whitin:J. Other species are allowed to be taken as bycatch am liInits

for these species are established as a percentage of the Pacific whitin:J quota (Table 27). '!he percentage liInitations apply to each 5,000 t of Pacific

whitin:J received fran u.s. vessels. If the retention liInit of a species is

reached prior to the receipt of 5,000 t of Pacific whitin:J, additional catches

of that species are required to be cH~ed until. 5,000 t of Pacific whitin:J

are received. '!he retention liInits allow u.s. fishay managersto 11X)nitorthe

Observer Coverageof Fishirg Fleets

'!he period of 1990 joint venture fishirg for Pacific whitinJ off the

Washirgton-Oregon-califonlla coast (Fig. 8) was divided into two seasons

(Fig. 9). '!he first season began on 3 April am continued until. 20 June when

the initial allocation was attained. '!he fishery reopened on 2 August whenit

received a reawortiOI'JlOOl1t of Pacific whitirg iran the danestic fishay. '!he

attained. Participatin:J in joint venture fishirg operations with u.s.

fishenleI1 were processinJ vessels fran Polam, Japan, am the U.S.S.R. In the

joint venture fishery, observers sampled a total of 1,882 days out of the

1,960 days foreign processors spent on the fishirg grounjs, providirg a level

of CClVerageof 96.0% (Table 28). '!he level of CClVeragein the joint venture

fishay for 1989 was 96.7%.

Estimates of u.s. Joint Venture catches

In 1990, the Pacific whitin:J joint venture fishay lan:ied 172,069 t of

gram:ifish, am Pacific whitin:J cc:t11prlsed170,972 t (99.4%) of the total catch

(Table 29). '!he catch of Pacific whitin:J taken by the joint venture fishery in 1990 was 16% less than the catch taken in 1989 bIt still :represented the

secon:i highest total taken by the canbi.nedforeign am joint venture fisheries

since the inception of the MFCMAin 1976 (Table 30). Of the bycatch taken in

1990, the majority was madeup of rockfish (excludin.J Pacific ocean perch) am
