Abstract

 From June to August 2010, the National Marine Fisheries Service’s Alaska Fisheries 

Science Center, Resource Assessment and Conservation Engineering Division, conducted its 

29th annual eastern Bering Sea (EBS) continental shelf bottom trawl survey of groundfish and 

invertebrate fauna. In addition, the 2010 survey coverage was expanded to include the northern 

Bering Sea (NBS). The expanded study area covered the entire Bering Sea continental shelf from 

20 to 200 m bottom depth to the U. S.-Russian Convention Line between the Alaska Peninsula and 

the Bering Strait, including Norton Sound. Three stern trawlers, the 43.5-m FV Alaska Knight, the 

40-m FV Aldebaran, and the 38-m FV Vesteraalen were chartered to sample this survey area. 

Demersal populations of fishes and invertebrates were sampled by trawling for 30 minutes at 

stations centered within a stratified systematic grid consisting of a total of 376 stations in the EBS 

and 145 stations in the NBS. 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. All survey stations were sampled successfully in the EBS, and all 

but three stations were sampled successfully in the NBS. 

For the fifth consecutive year, average surface (5.4°C) and bottom (1.4°C) water 

temperatures for the EBS shelf were well below the long-term means from 1982 to 2009 for the 

surface (6.6°C) and for the bottom (2.3°C). A total of 120 species of fishes representing 23 

families and 74 genera, as well as 199 species of invertebrates representing 14 phyla, were 

identified in the catches from both the EBS and NBS. Fish taxa in the EBS accounted for 74% of 

the total CPUE compared with the NBS where fish taxa accounted for only 38% of the total 

CPUE. In the EBS, walleye pollock (Theragra chalcogramma), Pacific cod (Gadus 

macrocephalus), yellowfin sole (Limanda aspera), and rock sole (Lepidopsetta spp.) comprised 
iv 

77% of the total fish biomass, and in the NBS, yellowfin sole and Alaska plaice (Pleuronectes 

quadrituberculatus) comprised 61% of the total fish biomass. The majority of invertebrate 

biomass in both the EBS (67%) and NBS (67%) consisted of echinoderms and crustaceans. 

Survey results presented herein include abundance estimates for fishes and invertebrates, 

geographic distributions and abundance-at-length of the more common fish species, and summary 

surface and bottom temperature data during the summer survey 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 

 From June to August 2010, the National Marine Fisheries Service (NMFS) Resource 

Assessment and Conservation Engineering (RACE) Division of the Alaska Fisheries Science 

Center (AFSC) conducted its 29th annual EBS (eastern Bering Sea) continental shelf bottom 

trawl (BT) survey of groundfish and invertebrate fauna. In addition, the 2010 survey coverage of 

the continental shelf was expanded to include the NBS (northern Bering Sea),which is bounded 

by the shelf break and the U.S.-Russian Convention Line in the west, the Bering Strait in the 

north, and Norton Sound in the east (Fig. 1). The 2010 EBS and NBS shelf surveys were 

conducted concurrently with the 2010 EBS upper continental slope BT survey (Hoff and Britt 

2011) and together they represented the most comprehensive BT survey coverage of the Bering 

Sea (roughly 800,000 km2

) since the U.S. government began scientific BT surveys in Alaska. 

 Sampling on the NBS shelf was done in conjunction with the annual EBS shelf bottom 

trawl survey. The methodology for sampling both the EBS and NBS was exactly the same, but 

the main objective for sampling each area was different. The EBS shelf supports one of the most 

productive groundfish and crab fisheries in the world (Bakkala 1993) including commercially 

valuable species such as walleye pollock (Theragra chalcogramma), yellowfin sole (Limanda

aspera), Pacific cod (Gadus macrocephalus), snow crab (Chionoecetes opilio), blue king crab 

(Paralithodes platypus), and red king crab (P. camtschaticus). Fishery-independent data from 

annual EBS bottom trawl surveys are vital to the management and conservation of commercial 

and non-target groundfish and crab species under the North Pacific Fishery Management Council 

(NPFMC) fisheries management plans. In contrast, the NBS has no large-scale commercial 

fisheries; however, climate change is a concern because of its potential to fundamentally alter the 

biological community thereby impacting fishes, crabs, marine mammals and the subsistence

fisheries of western Alaska fishing communities. To address concerns about climate change and 

its impacts on the NBS, the AFSC developed a Loss of Sea Ice (LOSI) Research Plan (Hollowed 

et al. 2007). A primary objective of the LOSI Research Plan was to conduct a series of bottom 

trawl surveys in the NBS for baseline data to monitor the distribution, abundance, and general 

ecology of marine animals living on or near the seafloor to determine the effects of climate 

change and the loss of seasonal sea ice. 

 Shared objectives for both the EBS and NBS BT surveys were to provide data on 

1) distribution, abundance, and biological condition of groundfishes, crabs, and other demersal 

macrofauna; 2) ongoing studies on the age and growth, biology, behavior, and dynamics of key 

ecosystem components; and 3) catch per unit effort (CPUE) and size composition data for the 

commercial fisheries of the United States. 

 This report presents results of a standardized BT survey conducted by the AFSC on both 

the EBS and NBS continental shelf in 2010. The EBS portion of this survey represents the 29th

contribution to the EBS shelf time series, and the combined EBS/NBS continental shelf BT 

survey is the first in a new time series. Data reports with results from earlier EBS BT surveys 

can be found in AFSC/NOAA Technical Memoranda (years 2008-2010) or in AFSC Processed 

Reports (prior to 2008) from the AFSC Publications Database 

(http://access.afsc.noaa.gov/pubs/search.cfm). Commercial king, snow, and Tanner crab 

fisheries in the Bering Sea and Aleutian Islands Regions are managed by the Alaska Department 

of Fish and Game (ADF&G) under a NPFMC fishery management plan. Detailed results for the 

analysis of crab data from this and previous surveys are presented in annual Bering Sea crab 

survey reports also available from the AFSC Publications Database.

History of Bering Sea Bottom Trawl Surveys 

 The involvement of the U.S. government in Bering Sea BT surveys dates back to the 

1940s when effort was engaged primarily in exploratory work for commercial fisheries 

resources (Zimmermann et al. 2009). Early efforts led to the development of a valuable singlespecies fishery in Alaska for red king crab (Paralithodes camtschaticus), and continued U.S. BT 

surveys into the 1970s focused on cooperative arrangements with private industry to study the 

biology, distribution, abundance, and best fishing practices for red king crab (Zimmermann 

et al. 2009). 

 The first large-scale systematic survey of the EBS shelf was conducted in 1975 under 

contract from the U.S. Bureau of Land Management to collect baseline data for assessing the 

potential impact of the growth in the offshore oil industry on the development of Bering Sea 

groundfish and crab fishery resources (Pereyra et al. 1976). During the 1975 baseline survey, 

sampling was conducted over the EBS shelf between the 20-m and 200-m isobaths from the 

Alaska Peninsula north to approximately 62°N. In 1979, a more 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 upper continental slope waters and part of the NBS. A hydroacoustic survey was 

also initiated in 1979 to assess the midwater component of the walleye pollock population. 

 Following the expansive 1979 effort, BT surveys continued on the EBS shelf on an 

annual basis, and in the combined NBS shelf and upper continental slope on a triennial basis. 

The survey trawl gear and sampling methods lacked consistency through 1981, hence the starting 

point for the shelf BT survey time-series is generally considered to be 1982, when the survey 

trawl and sampling practices were standardized to a systematically designed grid pattern of 

5
356 stations (Bakkala 1993). Beginning in 1987, survey coverage was increased to include more 

of the known ranges of walleye pollock and snow crabs by adding 20 stations in Strata 82 and 90 

up to the edge of the U.S.-Russian Convention Line (Fig. 2). 

 The triennial surveys of the NBS and EBS slope were discontinued after 1991 due to lack 

of funding; however, starting in 2000, the slope BT survey resumed on a biennial basis as a new 

time series using standard AFSC gear and methods (Stauffer 2004, Hoff and Britt 2011). In 

2010, the extension of the EBS shelf survey grid into the NBS was the start of a new time series 

because it was the first time that the systematic sampling design and standard sampling practices 

of the EBS shelf were applied in the NBS. 

Methods 

Survey Area and Sampling Design 

The standardized BT survey is based on a stratified systematic design consisting of a grid 

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, high-density “corner 

stations” are sampled to better assess local blue king crab concentrations (Fig. 1). For the first 

time in 2010, the standard sampling grid was expanded to include an additional 145 stations in 

the NBS shelf (Fig. 1). The northern extension was bounded by the U.S.-Russian Convention 

Line in the northwest, the Bering Strait in the north, and Norton Sound in the east. The results 

reported herein include data analyses for both the EBS and NBS.

Survey Vessels and Sampling Gear 

 From 3 June to 15 August 2010, sampling at survey stations in the EBS and NBS was 

coordinated between three chartered commercial fishing vessels: the FV Aldebaran, FV Alaska 

Knight, and FV Vesteraalen. All three vessels are house-forward trawlers with stern ramps. The 

Aldebaran has a length overall (LOA) of 39.6 m (130 ft), the Alaska Knight has an LOA of 

43.5 m (143 ft), and the Vesteraalen has an LOA of 38 m (125 ft). The AFSC equipped each of 

the vessels with standard 83-112 Eastern otter trawls, which have 25.3-m (83 ft) headropes and 

34.1-m (112 ft) footropes (Fig. 3). Survey trawls were towed behind 816 kg, 1.8 × 2.7 m, steel 

V-doors and paired 54.9 m (30-fathom) dandylines. Each lower dandyline had a 61 cm chain 

extension connected to the lower wing edge to improve bottom-tending characteristics. 

 All fishing operations were conducted in rigorous compliance with national and regional 

protocols detailed in Stauffer (2004). Any hauls that sustained significant gear damage or 

contained debris such as discarded crab pots were resurveyed immediately following the 

unsucessful haul. 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 for each 

tow 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 

calculated for each vessel (Rose and Walters 1990; Fig. 4).

EBS Sampling Logistics and Stratification Scheme 

Both the Alaska Knight and Aldebaran conducted the standard EBS shelf survey charters 

beginning in Dutch Harbor, Alaska, on 3 June 2010. Survey trawl sampling of the EBS shelf 

began in eastern Bristol Bay and proceeded westward to the shelf edge (Fig. 2). The progression 

from east to west was established in response to movements of yellowfin sole and perhaps other 

species, which may be migrating eastward during the course of the survey (Smith and Bakkala 

1982). The Aldebaran completed the standard EBS survey on 29 July after returning to Bristol 

Bay to resurvey 23 stations in an effort to assess the availability of mature red king crab to the 

survey after bottom temperatures increased from the original sampling of those stations (Fig. 2). 

The Alaska Knight completed sampling for the standard EBS survey on 4 August. 

For catch analysis, the EBS shelf was divided into 12 strata bounded by the 50-m, 100-m, 

and 200-m isobaths, a geographic stratum line separating the northwest and southeast shelf, and 

localized high-density strata in the regions around St. Matthew and Pribilof Islands (Fig. 2). This 

stratification scheme reflects the differences observed in Bering Sea groundfish distribution 

across the oceanographic domains, and the intention of the design was to reduce the variances of 

population and biomass estimates (Bakkala 1993). The purpose of high-density sampling in 

Strata 32, 42, 43, and 62 was to reduce variance estimates for blue king crab. Sampling density 

ranged from one station per 775 km2

 (Stratum 42) to one per 1,496 km2 (Stratum 82) and the 

sampling density for the entire EBS shelf was one station per 1,311 km2

 (Table 1).

NBS Sampling Logistics and Stratification Scheme 

Survey trawl sampling of the NBS shelf was conducted in late July and early August. 

The Vesteraalen conducted sampling in the NBS from 23 July to 15 August, the Aldebaran from 

30 July to 8 August, and the Alaska Knight from 4 August to 8 August. 

The NBS shelf was divided into three strata: one including the area north of St. Lawrence 

Island and Norton Sound and two others south of St. Lawrence Island separated by the 50-m 

isobath (Fig. 2). Sampling density was 1,367 km2 /station for Stratum 70, 1,475 km2 /station for 

Stratum 71, 1,475 km2 /station for Stratum 81, and 1,410 km2 /station for the total NBS (Table 1). 

Standard 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 grid circle, 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 if suitable 

bottom was found. 

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

and enumerated, while larger catches were weighed in aggregate and subsampled before sorting. 

After sorting subsampled catches, individual species were weighed in aggregate and counted, 

and these weights and numbers were expanded to the total catch. 

12
Fishes and invertebrates were identified and sorted to the lowest taxonomic level 

practicable. Due to low abundance (believed to be < 1%) of southern rock sole (Lepidopsetta 

bilineata) in the EBS 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 (Rajidae), 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 most 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 of that species were retained in the random 

subsample for length measurements by sex, up to a maximum of about 300 specimens per 

species. Fish lengths 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 1.0 centimeter (fork or total length). 

Unless retained for biological sampling by the International Pacific Halibut Commission (IPHC), 

Pacific halibut were measured upon capture and immediately returned to the sea in an effort to 

reduce mortality; weights of all Pacific halibut were estimated using an IPHC length-weight 

regression.

Sagittal otoliths were collected from 11 fish species in the EBS and 6 fish species in the 

NBS (Table 3). In the EBS, three otolith pairs per sex per centimeter interval per vessel in both 

the northwest stratum and southeast stratum (up to 12 pairs total) were collected for Pacific cod, 

Alaska plaice (Pleuronectes quadrituberculatus), arrowtooth flounder (Atheresthes stomias), 

northern rock sole, flathead sole (Hippoglossoides elassodon), and Greenland turbot. Five 

otolith pairs per sex per centimeter interval per vessel in both the northwest stratum and 

southeast stratum (up to 20 pairs total) were collected for Bering flounder (Hippoglossoides 

robustus), starry flounder (Platichthys stellatus) and yellowfin sole. Otoliths from all Pacific 

halibut collected aboard the Aldebaran were sampled by the IPHC for population and growth 

analyses. For walleye pollock otolith sampling, the eastern Bering Sea was divided into lowand 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. In addition, if 20 or more juvenile walleye pollock (< 20-cm) were 

present in a sample, two additional otolith pairs were taken from a random sample of those 

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

taken. Otoliths for groundfishes were preserved in 50% glycerol-thymol solution. 

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). Some species 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 of fish 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 strata and for the total survey area in the EBS and NBS. 

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 abundance-at-length estimates were summed for the total estimated 

size composition for the overall survey area in both the EBS and NBS. 

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. The most current information about age, growth, and 

population analyses are presented in the 2010 NPFMC Stock Assessment and Fishery Evaluation 

Report for the Groundfish Resources of the Bering Sea/Aleutian Islands Region. 

18
Additional Research Projects 

 In addition to the survey operations, numerous special research projects and collections 

were undertaken during the 2010 survey (Table 4). Six projects were collection requests for 

either photos or specimens of fishes or crabs for educational outreach and reference material. 

Other projects conducted for the RACE Division included studies of 1) summer zooplankton 

biomass; 2) acoustic data collection for augmenting the midwater assessment of walleye pollock;

3) survey trawl catchability of snow crab in cooperation with the Bering Sea Fisheries Research 

Foundation (BSFRF); 4) Bering flounder reproductive biology; 5) collection of in situ light 

intensity measurements; 6) characterization of the benthic infauna community; 7) visual 

monitoring for bitter crab and black mat syndromes; and 8) Tanner crab stomach contents. The 

REFM Division’s special study projects included: 1) a short-tailed albatross survey; 2) octopus 

identification and collections of individual weights; 3) collection of data on trophic interactions 

and feeding ecology of commercial fishes (Table 5); and 4) whole Arctic cod collections. 

Projects from outside the AFSC included 1) collection of biological and oceanographic data for 

the Bering Sea Integrated Ecosystem Research Program (BSIERP) and the Pacific Marine 

Environmental Laboratory (PMEL); 2) zoarcoid collections for Virginia Institute of Marine 

Science (VIMS); 3) reproductive potential of snow and Tanner crabs for ADF&G; and 4) genetic 

population structure of snow crab for University of Alaska, Fairbanks. Data for additional 

research projects were collected at sea and disseminated to the requesting principal 

investigator(s). To acquire the details of any special project or collection, please contact the 

investigator(s) designated in Table 4.

Results and Discussion 

 All 376 of the EBS stations were successfully sampled but only 142 of the 145 NBS 

stations were successfully sampled (Fig. 2). One NBS station had to be abandoned because it 

was too shallow for safe trawl operations, and two other stations were attempted once and then 

abandoned because it was concluded that further attempts at trawling within the grid cell would 

have likely resulted in significant gear damage. Haul data for successfully trawled stations used 

in the analyses are listed in Appendices A1 to A3 along with 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. 

 

Ocean Conditions 

 Sea surface temperatures recorded during the survey ranged from 0.5° to 17.7°C (Fig. 5). 

In the EBS south of 60°N, surface temperatures increased from east to west across the shelf. 

Surface temperatures in the NBS were generally higher and above 10°C in Norton Sound. 

Bottom temperatures ranged from –1.6° to 12.3°C (Fig. 6) with warmer bottom temperatures 

(> 3.0°C) occurring along the inner shelf from northern Bristol Bay to Norton Sound, and on the 

outer shelf south of 59°N. 

Average surface and bottom temperatures on the EBS shelf show similar interannual 

variability (Fig. 7). The annual EBS shelf BT survey begins in the late spring soon after the 

seasonal ice has receded and a layer of cold bottom water (≤ 2°C) persists on the middle shelf. 

The size of the cold pool fluctuates inter-annually and on longer time scales, and its extent on the 

middle shelf is determined by the extent of seasonal ice cover the preceding winter as well as by 

other oceanographic and meteorological conditions (Wyllie-Echeverria and Wooster 1998). 

22
Changes in the mean bottom temperature relative to the long-term average became more extreme 

starting in 1999, which was the coldest year. This was followed by a steady increase that resulted 

in an extended warm period lasting from 2001 to 2005 followed by an acute decrease and an 

extended cold period from 2006 to the present survey. Average surface (5.4°C) and bottom 

(1.4°C) water temperatures for the EBS shelf were slightly higher than in 2009, but well below 

the long-term means from 1982 to 2009 for the surface (6.6°C) and for the bottom (2.3°C; 

Fig. 7). 

Species Composition 

A total of 120 fish species representing 23 families and 74 genera were identified in the 

survey catches from both the EBS and NBS (Appendix C1). The EBS had a total of 101 fish 

species, 49 of which did not occur in the NBS. In comparison, the NBS had 71 total fish species, 

19 of which did not occur in the EBS (Table 6). Seven of the 19 species only occurring in the 

NBS (Table 6) have only been documented north of 60°N (Mecklenburg et al. 2002). 

Relative Abundance

 The relative abundance of the 12 most common fishes in each the EBS and NBS are 

presented in Figure 8. The top 12 fish taxa in the EBS accounted for 74% (230 kg/ha) of total 

catch CPUE (312 kg/ha) and 97% of total fish CPUE (236 kg/ha), compared with the NBS where 

the top 12 fish taxa accounted for only 38% (59 kg/ha) of the total catch CPUE (147 kg/ha) and 

94% of total fish CPUE (59 kg/ha). 

 The lower fish biomass in the NBS is consistent with results of a broader analysis of all 

survey years showing decreasing fish biomass with increasing latitude on the Bering Sea

continental shelf (Stevenson and Lauth in review). The relative abundance of flatfishes and 

gadids were high in both the EBS and NBS, but the species comprising each taxonomic group 

and their proportion of the total biomass were different between the two areas. In the EBS, there 

were 16 different flatfish species that together comprised more than half of the total fish biomass 

(54%) with yellowfin sole (20%) and northern rock sole (18%) having the greatest proportions. 

This contrasted with the NBS where there were nine flatfish species with yellowfin sole (36%) 

and Alaska plaice (25%) making up a majority of the total fish biomass. Seven flatfish species 

that were present in the EBS were absent from catches in the NBS including arrowtooth 

flounder, Kamchatka flounder (Atheresthes evermanni), butter sole (Isopsetta isolepis), Dover 

sole (Microstomus pacificus), flathead sole, rex sole (Glyptocephalus zachirus) and southern 

rock sole (Table 6). One flatfish species, the Arctic flounder (Liopsetta glacialis), was only 

present in the NBS. 

 Walleye pollock and Pacific cod together comprised 40% of the total fish biomass in the 

EBS compared to only 5% in the NBS. The abundance of walleye pollock was relatively high in 

the EBS middle and outer shelf compared to the inner shelf and in the NBS where bottom depths 

are generally less than 50 m (Fig. 9). Unlike the EBS, two other gadids, Arctic cod (Boreogadus 

saida) and saffron cod (Eleginus gracilis), were among the 12 most abundant fish species in the 

NBS. For a descending rank of all organisms caught in each area, see Appendix B1 (EBS) and 

Appendix B2 (NBS).

 Biomass, Abundance, Distribution, CPUE, and Size Composition 

 of Principal Species and Species Groups 

Total demersal animal biomass for the EBS was estimated at 15.6 million metric tons (t) 

and for the NBS at 3.0 million t. In the EBS, the proportion of fishes (75%; Table 7a) was three 

times higher than invertebrates (25%; Table 7b); however, the converse was true for the NBS 

where the proportion of fishes (40%; Table 8a) was lower than invertebrates (60%; Table 8b). 

Pleuronectids dominated the fish biomass in both the EBS (6.3 million t) and NBS (0.8 million 

t), and gadids were the second most abundant fish group in both areas. Walleye pollock were the 

most abundant gadid in the EBS (Table 7a) and saffron cod the most abundant in the NBS (Table 

8a). Echinoderms and crustaceans were the major invertebrate taxa comprising 17% of the total 

animal biomass in the EBS (Table 7b) and 40% in the NBS (Table 8b). 

Survey results for major fish fauna are presented in maps of geographic distribution and 

abundance, plots of total abundance-at-size, and tables with estimates of biomass and population 

number. Major species presented include walleye pollock (Figs. 9-10 and Table 9a, b), Pacific 

cod (Figs. 11-12 and Table 10a, b), yellowfin sole (Figs. 13-14 and Table 11a, b), grouped 

northern and southern rock sole (Figs. 15-16 and Table 12a, b), flathead sole (Figs. 17-18 and 

Table 13a, b), Bering flounder (Figs. 19-20 and Table 14a, b), Alaska plaice (Figs. 21-22 and 

Table 15a, b), Greenland turbot (Figs. 23-24 and Table 16a, b), arrowtooth flounder (Figs. 25-26 

and Table 17a, b), Kamchatka flounder (Figs. 27-28 and Table 18a, b), and Pacific halibut (Figs. 

29-30 and Table 19a, b). Appendix D contains population estimates by sex and size class for all 

11 of these fish species.

Summary of Results for Selected Major Eastern and Northern Bering Sea Fish Fauna 

Walleye Pollock (Theragra chalcogramma) 

Walleye pollock were captured at 82% of the stations sampled in the EBS and NBS. 

Catch rates were lowest in the inner and middle shelf, and highest north of 56°N and west of 

170°W where bottom depths were greater than 70 m and bottom water temperatures were above 

-1°C (Fig. 9). The total estimated biomass of walleye pollock in the EBS was 3.74 million t 

(Table 9a), which was a 64% increase from the 2009 estimate of 2.28 million t. The higher 

biomass corresponded to a 56% increase in population size from 3.5 billion to 5.4 billion fish 

(Table 9b). The biomass and population size in the NBS were comparatively small with 21,000 t 

and 66 million fish. 

One-year-old pollock, represented by lengths ranging from 10 to 20 cm, had a modal 

peak of 80 million in the EBS and 15 million in the NBS (Fig. 10). These 10-20 cm juveniles 

were mostly found at stations where catch rates were less than 75 kg/ha (Fig. 9) and they were 

generally segregated from larger adults (> 40 cm) in the middle and outer shelf. The abundanceat-size plot of pollock in both the NBS and EBS inner shelf shows a large mode of age-1 pollock 

followed by a large gap and then a small mode of much larger pollock having lengths greater 

than 60 cm (Fig. 10). Age-2 and age-3 pollock (length range of 20-40 cm) are generally 

underrepresented in survey trawl catches; however, relatively small modes for both year classes 

are present in the plot of abundance-at-size (Fig. 10).

Pacific Cod (Gadus macrocephalus)

Pacific cod were broadly distributed across the EBS shelf and were present at 91% of the 

sampled stations compared to a patchy distribution in the NBS, where they were present at only 

41% of the stations (Fig. 11). The biomass of Pacific cod in the EBS was 0.87 million t 

(Table 10a), which was more than double the 2009 estimate, and population numbers increased 

24% to 892 million, which was the highest since 2001 (Table 10b; Thompson et al. 2010). The 

biomass and population size in the NBS were comparatively small with 29,000 t and 8.9 million 

fish (Table 10a, b), although more than 50% of the Pacific cod in the NBS were very large (over 

60 cm; Fig. 12). The large increase in biomass and the presence of high abundance at several 

modal lengths above 30 cm suggest strong recruitment from the 2006 to 2008 year classes (Fig. 

12). 

 

Yellowfin Sole (Limanda aspera)

Yellowfin sole were distributed across the shelf to a bottom depth of 100 m with highest 

catch rates occurring in Bristol Bay and along the inner shelf from the Alaska Peninsula north to 

St. Lawrence Island (Table 11a, b; Fig. 13). The biomass on the EBS shelf, where the world’s 

largest flatfish commercial fishery operates (Wilderbeur et al. 2010), increased from 1.7 to about 

2.4 million t (Table 11a) and the population number decreased slightly from 8.4 billion to 

10.1 billion (Table 11b). In the NBS, there was an additional 0.43 million t of yellowfin sole 

(Table 11a), but this area is not opened to large-scale commercial fishing. 

Yellowfin sole are segregated by depth based on size and sexual maturity (Nichol 1997, 

1998). The size composition of yellowfin sole during the 2010 survey differed between the EBS 

and NBS, between the EBS middle and inner shelf, and between males and females on the EBS 

40
middle shelf (Fig. 14). Sexually mature yellowfin sole undergo an annual spring-summer 

spawning migration across the shelf into the shallow waters of Bristol Bay and off Nunivak 

Island (Bakkala 1981) with most spawning activity occurring at bottom depths < 30 m (Nichol 

1995). Sexually immature individuals, which can be up to 6-8 years old, undergo an ontogenetic 

migration rather than a spawning migration by moving deeper as they get older (Nichol 1997). 

Length or age at sexual maturity differs for males and females causing further size segregation 

among spawning and non-spawning portions of the population (Nichol 1998). 

 

Northern and Southern Rock Sole (Lepidopsetta spp.)

Rock sole were broadly distributed across the shelf with highest concentrations in Bristol 

Bay and around the Pribilof Islands (Table 12a, b; Fig. 15). From 2009, estimated biomass in the 

EBS increased 33% to 2.06 million t (Table 12a) and the estimated population number increased 

by 13% to 9.3 billion (Table 12b). Less than 1% of the total shelf-wide biomass was in the NBS. 

Mean length of rock sole increased moving deeper across the EBS shelf in contrast to the NBS 

where the mean size was very similar to EBS outer shelf (Fig. 16). Spawning and feeding 

migrations for rock soles are poorly understood, but in general it is believed that rock sole use 

active tidal stream transport during nighttime hours (Nichol and Somerton 2009) to migrate from 

shallow summer feeding grounds to deep winter and spring spawning grounds (Fadeev 1965, 

Shubnikov and Lisovenko 1964). 

Flathead Sole (Hippoglossoides elassodon)

Flathead sole and Bering flounder are members of the same genus, and they are difficult 

to distinguish based on appearance. Consequently, the accuracy of identifications in the

commercial fishery data is unknown and the two species are combined into a single stock 

assessment by the NPFMC (Stockhausen et al. 2010). In contrast, BT survey scientists are 

trained to make reliable field identifications for flathead sole and Bering flounder; hence, results 

here are presented by species. Despite belonging to the same genus and having a similar 

appearance, the two species have entirely different geographic distributions (Fig. 17; compare 

with Bering flounder below). Flathead sole were present at 68% of the EBS stations and 

completely absent in the NBS (Fig. 17). The highest catch rates of flathead sole were at depths 

below 70 m and the estimated biomass of 0.49 million t (Table 13a) and population number of 

1.6 billion (Table 13b) were both increases from 2009 levels. A similar size range of flathead 

sole (10-50 cm) was observed at all depths and the mean length for the entire EBS shelf was 

29.7 cm (Fig. 19). 

Bering Flounder (Hippoglossoides robustus) 

Bering flounder is an arctic species with a distribution extending north into the Chukchi 

Sea (Mecklenburg et al. 2007). The spatial distribution of Bering flounder in the EBS and NBS 

BT survey was mostly contained within an area where bottom water temperatures were ≤ 2°C 

(Fig. 19). The highest catch rates were in the middle shelf close to the U.S.-Russian Convention 

Line where bottom water temperatures were below 0°C (Fig. 19). The total estimated biomass 

for the EBS and NBS was 24,000 t (Table 14a) and the total population number was 364 million 

fish (Table 14b). Seventy-nine percent of the total population consisted of juveniles measuring 

≤ 20 cm (Fig. 20). Discounting the NBS portion, the 2010 abundance of juvenile Bering 

flounder in the EBS was 4 to 13 times greater than any survey year going back to 1999. The 

54
relatively high abundance of juvenile Bering flounder in 2010 suggests that environmental 

conditions during the recent cold period may have been favorable for recruitment of that species. 

Alaska Plaice (Pleuronectes quadrituberculatus) 

Alaska plaice were distributed throughout the inner and middle shelf from Bristol Bay to 

the Bering Strait with the highest densities found along the 50 m contour and south of 

St. Lawrence Island (Fig. 21). The summer distribution of Alaska plaice appeared to be 

unaffected by cold bottom tempertures because catch rates were highest inside the cold pool even 

where bottom water temperatures were below -1°C (Fig. 21). Alaska plaice are well-adapted to 

sea water temperatures near the freezing point (-1.9°C) because they are capable of synthesizing 

an antifreeze glycoprotein to prevent ice crystal formation in their blood (Knight et al. 1991). 

Results from this year and previous AFSC trawl surveys show that females attain a 

maximum length about 10 cm greater than males, and that the proportion of males in the 

population increases with decreasing bottom depth (Fig. 22, Zhang et al. 1998). Males were 

totally absent on the EBS outer shelf but increased to 36% of the population on the middle shelf 

and 69% of the population on the inner shelf (Fig. 22). 

 In 2010, the estimated biomass of Alaska plaice in the EBS was 498,000 t (948 million 

fish) with an additional 303,000 t (592 million fish) in the NBS (Table 15a, b). Biomass 

estimates on the EBS shelf alone have fluctuated between 423,000 t and 645,000 t over the past 

20 years. It was evident from the expanded coverage of the 2010 survey that a large proportion 

of Alaska plaice can occupy the area north of the standard annual EBS survey. Interpreting a 

meaningful relative trend in Alaska plaice abundance in the EBS time series is difficult without

more knowledge about the variability in seasonal migratory patterns of Alaska plaice between 

the EBS and NBS. 

Greenland Turbot (Reinhardtius hippoglossoides) 

Greenland turbot has a circumpolar distribution and, on the Pacific side, is most abundant 

in the Bering Sea continental shelf and upper slope (Allen and Smith 1988). The total estimated 

biomass on the Bering Sea continental shelf was 23,538 t (Table 16a) with the highest catch rates 

of Greenland turbot in the northernmost section of the EBS outer shelf (Fig. 23). Eighty-four 

percent of the total shelf biomass was on the EBS outer shelf, 15% on the middle shelf, and the 

remaining 1% on the combined EBS inner shelf and the NBS (Table 16a, Fig. 23). The 

estimated number of Greenland turbot on the EBS shelf was 138 million (Table 16b) which was 

the highest population abundance in the 29-year time series. As is generally the case on the EBS 

shelf BT survey, a majority (98%) of the Greenland turbot were smaller than 50 cm (Fig. 24). In 

contrast with the EBS continental slope BT survey, a majority of Greenland turbot are > 60 cm 

(Fig. 67 in Hoff and Britt 2011). In general, the maximum size of Greenland turbot differs by 

sex being about 80 cm for males and 110 cm for females. 

Sizes-at-age extrapolated from lengths of Greenland turbot observed in BT surveys 

(Gregg et al. 2006, Ianelli et al. 2010) are consistent with a hypothesized framework for 

spawning, recruitment, and ontogentic migration (Alton et al. 1988, Sohn et al. 2010). 

Greenland turbot spawn on the continental slope between Unimak Pass and the Pribilof Islands 

(Alton et al. 1988). Once hatched from eggs, the larvae and juveniles undergo a prolonged 

pelagic phase drifting northward in the Bering Slope Current to the vicinity of St. Matthew 

Island, where they settle on nursery grounds (Sohn et al. 2010). After spending 4 to 5 years on 

68
the shelf, Greenland turbot undergo an ontogenetic migration down the slope and back toward 

the spawning area in the south (Alton et al. 1988). 

Arrowtooth Flounder (Atheresthes stomias) 

Arrowtooth flounder were not present within the NBS but were distributed in the EBS 

along the outer shelf and at the deeper end of the middle shelf with a small portion of the 

population in southern Bristol Bay (Fig. 25). The cross-shelf spatial distribution of arrowtooth 

flounder may be affected by the extent of the cold bottom water ≤ 1°C on the EBS middle shelf. 

In 2010, a cold year, the highest catch rates were seaward of the 1°C isotherm and arrowtooth 

flounder were absent from more than half of the stations sampled in the middle shelf (Fig. 25). 

In contrast, 2005 was the warmest year on record and arrowtooth flounder were more broadly 

distributed across the middle shelf south of the 1°C isotherm near St. Matthew Island (Lauth and 

Acuna 2007). 

The 2010 estimates of total survey biomass increased from 0.41 million t in 2009 to 

0.53 million t (Table 17a), as did the estimated survey population number from 0.9 billion to 

about 1.1 billion (Table 17b). The lengths of arrowtooth flounder ranged from 7 to 90 cm and 

the mean size for the population was 34.7 cm (Fig. 26). In addition to being found on the shelf, 

arrowtooth flounder are broadly distributed along the EBS continental slope where lengths 

exceed 30 cm and the mean length is much higher (46.8 cm; Fig. 69 in Hoff and Britt 2011). 

Similar to Greenland turbot, the maximum size of females (80 cm) is about 30 cm greater than 

males (50 cm; Fig. 26 and Hoff and Britt 2011). Another consistent pattern evident in all Alaska 

BT surveys is that there is a higher ratio of females to males in BT catches, which may be due to 

males having a higher mortality rate than females (Wilderbuer et al. 2010).

Kamchatka Flounder (Atheresthes evermanni) 

Kamchatka flounder are similar in appearance to the congeneric arrowtooth flounder 

(Yang 1988), and it wasn’t until 1994 that field characters were established to reliably 

distinguish between the two species during AFSC BT surveys. The spatial distribution of the 

two species overlap but Kamchatka flounder generally has higher catch rates on the northwest 

relative to the southeast shelf (Fig. 27). Trends in relative abundance are similar but the biomass 

and population size of Kamchatka flounder are about one-tenth that of arrowtooth flounder. 

From 2009 to 2010, the total survey biomass of Kamchatka flounder increased from 50,000 to 

58,000 t (Table 18a) and the population increased from 84 million to 132 million fish (Table 

18b). The measured lengths of Kamchatka flounder on the EBS shelf ranged from 7 to 84 cm 

and had a mean of 30.6 cm (Fig. 28). Similar to arrowtooth flounder, the portion of the 

Kamchatka flounder population inhabiting the EBS slope has a greater mean length (55.2 cm; 

Hoff and Britt 2011) than on the shelf and females attain a greater maximum size (Fig. 28). A 

characteristic that distinguishes Kamchatka from arrowtooth flounder is that the proportion of 

females to males in the Kamchatka flounder population is roughly equal (Fig. 28). 

Pacific Halibut (Hippoglossus stenolepis) 

Pacific halibut were present at 78% of the stations sampled in the EBS with the highest 

density catches along the inner southeastern half of the shelf (Fig. 29). Other than some 

relatively high catch rates north of Nunivak Island close to shore (Fig. 29), where bottom water 

temperatures were > 3°C (Fig. 6), Pacific halibut were scarce in the NBS, being present at only 

28% of the stations sampled. The 2010 estimated biomass of 198,000 t (Table 19a) was 60% 

greater than the mean for 1982-2009 (124,000 t) and the highest in the EBS time series. The 

78
2010 population of 107 million halibut (Table 19b) was a drop in number from the years 2006-

2008 (108-235 million), but it was an increase from 2009 (102 million) and it was 95% greater 

than the long-term average population size from 1982 to 2009 (55 million). Increases in 

abundance during recent years and the presence of several size modes (Fig. 30) indicate the 

presence of several strong year classes of Pacific halibut on the EBS shelf. 

Research and management of Pacific halibut stocks is the responsibility of the IPHC and 

their stock assessments include all available fisheries and scientific survey data from the U.S. 

and Canada (Hare 2010). The AFSC BT survey provides an important estimate of Pacific 

halibut abundance-at-length on the EBS shelf, especially for tracking strong incoming year 

classes. However, the BT survey gear is size-selective for Pacific halibut (< 100 cm; Fig. 30) 

and an adjustment for size-selectivity must be made before BT data from the EBS shelf can be 

incorporated into the Pacific halibut stock assessment model (Hare 2010). In 2006, the IPHC 

standardized setline survey added 100 EBS shelf stations for a comparison to the area swept 

estimates from our BT survey (Clark and Hare 2007). The comparison study was used to derive 

a size selectivity schedule that was applied to the EBS BT survey data to create an index of shelf 

abundance for the Pacific halibut stock assessment model (Hare 2010).

Biomass, Abundance, Distribution and CPUE of Other Fish Taxa 

Total biomass and population size were estimated for an additional 24 fish species that 

were common in either the EBS and NBS or both (Tables 20 to 21). For each of the 24 species, 

there is a corresponding map showing the geographic distribution and relative abundance (Figs. 

31 to 55). 

Spatial Distribution of Selected Invertebrates 

Plots of the broad spatial distribution patterns for five major invertebrates on the 

combined EBS and NBS continental shelf are presented in Figures 56 to 60. The purple sea star, 

(Asterias amurensis), is common in the Bering and Chukchi Seas (Hamizaki et al. 2005, Feder et 

al. 2005) and it was the invertebrate taxon with the highest ranked catch rate by weight in both 

the EBS (Appendix C1) and NBS (Appendix C2). Catch rates for the purple sea star were 

highest in the middle shelf between the Pribilof Islands and Nunivak Island and along the inner 

shelf from Bristol Bay to the Bering Strait (Fig. 56). 

Figures 57 to 60 show the shelf-wide distributions of the four major commercial crab 

species: red king crab, blue king crab, snow crab (Chionoecetes opilio), and Tanner crab 

(Chionoecetes bairdi). Commercial crab stocks are managed by the ADF&G with federal 

oversight by NMFS. For more detailed information on BT survey results for commercial crab 

refer to Chilton et al. (2011), and for the most recent modeling data on the status of these 

commercial crab stocks, refer to the annual Stock Assessment and Fishery Evaluation report 

prepared by the NPFMC.

Acknowledgments 

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

Alaska Knight, and FV Vesteraalen. Without their expertise, goodwill, and sacrifice, this survey 

would not be possible. Thank you to the Trident Corporation, United States Seafoods, and 

Vesteraalen LLC for making the vessels available and always maintaining safety as a top 

priority. Great appreciation is also extended to all the scientists, researchers, contractors, interns, 

and volunteers who worked tirelessly aboard each vessel to complete the survey in a safe and 

successful manner. Thanks also to Norton Sound Economic Development Corporation and 

Kawerak, Inc. for providing personnel to participate in the survey. The survey would not have 

been possible without the major contributions from other AFSC groups including the Net Shed, 

Research Survey Support Team, Data Management Group, and the Administrative team. 

Finally, appreciation is extended to the reviewers of this document whose excellent comments 

and suggestions greatly improved it.

Appendix A: Station and Catch Data

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

survey stations in the eastern Bering Sea and 142 successfully completed standard survey 

stations in the northern Bering Sea. In using the tables, the following should be noted: 

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

 Time (ADT). 

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.
