AFSC/ABL: Exxon Valdez Trustee Hydrocarbon Database

This hydrocarbon database was initiated after the Exxon Valdez oil spill in 1989. The first version was as an RBase database, PWSOIL(Short, Heintz et al. 1996). It migrated to a proprietary structure in 1997, EVTHD (Exxon Valdez Oil Spill Trustee Council Hydrocarbon Database) and contained the collection and hydrocarbon analysis information for environmental samples obtained for the Exxon Valdez National Resource Damage Assessment and Restoration efforts. The data were organized into three matrix types, tissues, sediment, and seawater. The analytical results included concentrations of 63 hydrocarbons, summary statistics for the evaluation of the hydrocarbon sources and laboratory quality control data. Features of the database included identification of replicate samples, presentation of results in dry or wet weight, optional correction for method detection limits (MDL) of the analytes, and easy identification of samples contaminated with Exxon Valdez crude oil. This structure, written in Visual Basic, ceased to function well when Windows operating systems were upgraded to XP and the data were moved to a Microsoft Access format. The 2014 version continues in Access and is described in the included lexicon document. The 2014 version also includes a data analysis tool (Excel Office 2007 or greater) that flags recovery problems, provides method detection limit filtration (MDL), and source oil modeling.  The data should not be used without understanding these details.  Further instructions are in the lexicon document.

AFSC/ABL: 2007 Chum Salmon Bycatch Sample Analysis  Bering Sea

A genetic analysis of samples from the chum salmon (Oncorhynchus keta) bycatch of the 2007 Bering Sea walleye pollock (Theragra chalcogramma) trawl fishery was undertaken to determine the overall stock composition of the sample set. Samples were genotyped for eleven microsatellite markers and results were estimated using the current chum salmon microsatellite baseline. In 2007, genetic samples were collected opportunistically as part of a special project, but sample biases have the potential to affect stock composition analysis results. Consequently, stock composition estimates apply to the sample set and may not represent the entire chum salmon bycatch.  Based on the analysis of 1,279 chum salmon bycatch samples collected throughout the 2007 Bering Sea trawl fishery, North Asian (35%), East Asian (34%), and Eastern Gulf of Alaska/Pacific Northwest (16%) stocks dominated the sample set, with smaller contributions from Western Alaska (10%) and Upper/Middle Yukon River (5%) stocks. The estimates for the 2007 chum salmon bycatch sample set were similar to the 2005, 2006, and 2009 chum salmon bycatch estimates, suggesting consistency of the regional stock contributions across years. Analysis of temporal groupings within the groundfish B season revealed changes in stock composition during the course of the season with decreasing contribution of Upper/Middle Yukon stocks over time, but leaves unanswered whether these changes are due to temporal or spatial differences in the sample set.

AFSC/ABL: Movements of Yukon River Chinook salmon

Upriver movements were determined for Chinook salmon Oncorhynchus tshawytscha returning to the Yukon River, a large, relatively pristine river basin. A total of 2,860 fish were radio tagged during 2002-2004, and 2,790 fish (98%) tracked upriver. Most fish exhibited continual upriver movements and strong fidelity to the terminal tributaries entered, with only a small percentage (2.5%) deviating from this pattern. Average movement rates were substantially slower for fish spawning in lower river tributaries (28-40 km d-1) compared to upper basin stocks (52-62 km d-1). Three distinct migratory patterns were observed, including a gradual decline, pronounced decline, and substantial increase in movement rate as the fish moved upriver. Stocks destined for the same region exhibited similar migratory patterns. Migratory patterns among individual fish within a stock showed substantial variation, but tended to reflect the regional pattern. Differences between consistently faster and slower fish explained 74% of the within-stock variation, whereas relative shifts in sequential movement rates between hares (faster fish becoming slower) and tortoises (slow but steady fish) explained 22% of the variation. Pulses of fish moving upriver were not cohesive. Fish tagged over a 4-day period took 14 and 16 d to pass tracking station sites 580 and 872 km upriver, respectively. Movement data provided valuable insights into the run dynamics of the return, but individual variation among fish complicates efforts to manage in-river fisheries. The diverse migratory patterns exhibited by the fish also suggest that movement studies based on small numbers of individuals may not adequately reflect the patterns exhibited by the larger population. Movement rates were substantially faster and the percentage of atypical movements considerably less than reported in more southern drainages, but may also reflect the pristine conditions within the Yukon River, wild origins of the fish, and relatively discrete run timing of the returns.

AFSC/ABL: Deep-Water Longline Survey for Giant Grenadier and Sablefish in the Western Gulf of Alaska

An experimental bottom longline survey was conducted at depths >1,000 m in the western Gulf of Alaska in August 2008.  The objective was to investigate the abundance and biological characteristics of giant grenadier (Albatrossia pectoralis) and sablefish (Anoplopoma fimbria) in deep waters of the Gulf of Alaska that have not been previously sampled in fishery surveys.  Several difficulties were encountered during the fishing operations which indicate special problems may occur when fishing longlines at these depths, including substantial gear drift after setting and hang-ups on the bottom that caused the longline to part.  Although results were not conclusive because only stations in the western Gulf of Alaska were sampled, there was consistency in the results which provides an indication of fish abundance and distribution in depths >1,000 m.  Catch rates of giant grenadier were relatively high, although not as large as those in nearby longline survey stations in depths <1,000 m.  Female giant grenadier were much larger in size at the deep-water stations, and their weight averaged 69% greater than females at depths <1,000 m.  Males, which comprise a low percentage of the catch in shallower water, were caught in much higher numbers at the deep-water stations.  Catch rates for sablefish at the deep-water stations were extremely low, and it appears abundance of sablefish is negligible in the western Gulf of Alaska at depths >1,000 m.  Besides giant grenadier, Pacific grenadier (Coryphaenoides acrolepis) was the only other species caught in substantial numbers.  At one deep-water station, Pacific grenadier were extremely abundant and were caught on 56% of the longlines hooks.

AFSC/RACE/MACE: Results of 2014 Acoustic-trawl survey of the Shumagin Islands and Sanak Trough dy1401

The surveyâs primary objective was to collect acoustic data and trawl information to estimate midwater abundance and distribution of walleye pollock (Gadus chalcogrammus) in the Gulf of Alaska (GOA) Shumagins Region during late winter and early spring. Acoustic data were collected using five split-beam transducers (18, 38, 70, 120, and 200 kHz) and Simrad ER60 scientific echo sounders. Midwater and near-bottom acoustic backscatter was sampled using an Aleutian Wing 30/26 Trawl (AWT) and a poly Norâeastern bottom trawl (PNE) with roller gear. This long-running survey has consistently provided data on the pollock population in the western GOA during winter and spring months.

AFSC/ABL: 2008 Chum Salmon Bycatch Sample Analysis  Bering Sea

A genetic analysis of samples from the chum salmon (Oncorhynchus keta) bycatch of the 2008 Bering Sea walleye pollock (Theragra chalcogramma) trawl fishery was undertaken to determine the overall stock composition of the sample set. Samples were genotyped for eleven microsatellite markers and results were estimated using the current chum salmon microsatellite baseline. In 2008, genetic samples were collected opportunistically as part of a special project, but sample biases have the potential to affect stock composition analysis results. Consequently, stock composition estimates apply to the sample set and may not represent the entire chum salmon bycatch.  Based on the analysis of 629 chum salmon bycatch samples collected throughout the 2008 Bering Sea trawl fishery, North Asian (27%), East Asian (35%), and Eastern Gulf of Alaska/Pacific Northwest (24%) stocks dominated the sample set, with smaller contributions from western Alaska (7%) and Upper/Middle Yukon River (6%) stocks. The estimates for the 2008 chum salmon bycatch sample set were similar to the 2005, 2006, 2007, and 2009 chum salmon bycatch estimates, suggesting consistency of the regional stock contributions across years. Analysis of temporal groupings within the groundfish B season revealed changes in stock composition during the course of the season with decreasing contribution of Eastern Gulf of Alaska/Pacific Northwest stocks over time, but leaves unanswered whether these changes are due to temporal or spatial differences in the sample set.

AFSC/ABL: Frederick Sound Echo-integrated Trawl Survey, 2001 to 2004

The acoustic trawl database for Frederick Sounds echo-trawl survey was conducted from 2001 to 2004. The surveys were conducted throughout most of the southern part of Stephens Passage and Frederick Sound in southeast Alaska and all their adjoining bays. Acoustic and trawl surveys were conducted every 3 months to verify acoustic signals and to collect biological data. This study was conducted to study the relationship between Steller sea lions (Eumetopias jubatus) and their prey. Acoustic equipment were calibrated before every trawl survey. Trawls were used to identify the fish species associated with a specific acoustic signal and to get length weight data per species. Acoustic data were analyzed by the same qualified acoustician throughout the surveys duration with calibrations entered into the analytical software after each calibration.
Trawl data were used to enumerate and identify all nekton found within the study area and to generate length frequencies, species composition and abundance by season. The acoustic data was use to generate biomass estimates for Pacific herring, Pacific hake and walleye pollock. Longlines were deployed to better identify and enumerate the benthic species not usually caught in pelagic trawls.

AFSC/ABL: Glacier Bay Harbor Seal Survey, 2004-2007

The acoustic data collected in Glacier bay from 2005  2007 was used to study the link between marine predator (harbor seals) diving behavior to local prey fields in contrasting habitats in a glacial fjord. Standardized acoustic surveys were setup and run monthly throughout the summer and throughout Glacier Bay. Fish species were identified from previous trawl surveys while acoustic data was used to locate prey within the bay and water column in association with Harbor seals. Acoustic equipment were calibrated each month and the data were analyzed by the same qualified acoustician throughout the surveys duration. Seals were identified, enumerated and GIS positioned in association with prey fields found with the acoustics.

AFSC/ABL: Genetic Analysis of Immature Bering Sea Chum Salmon: Part I. Baseline Evaluation

Chum salmon populations from across their geographic distribution have been analyzed with a set of SNP and microsatellite markers. As is typical for chum salmon populations, more genetic divergence was observed on larger geographic scales than on smaller regional scales. Strong divergence exists within and among the three regions of Asia, western Alaska, and the northeast Pacific. However, separation of coastal western Alaskan summer-run chum salmon populations, from Norton Sound to northern Bristol Bay remains problematic. The degree of divergence determines the spatial scale to which stock proportions of mixtures of chum salmon can be resolved. The baseline developed in this project will be used for mixture analyses to study the marine distribution of chum salmon populations in the Bering Sea. Scale and fin samples collected in the eastern Bering Sea will be used to determine whether the stock composition of chum salmon aggregations differ across areas, seasonally, and annually. Determining the stock distributions of these mixtures will provide information on the migratory pathways of chum salmon in the Bering Sea and the potential impact of bycatch of coastal western Alaskan chum salmon in the Bering Sea pollock fishery.

AFSC/ABL: Origins of salmon seized from the F/V Petropavlovsk

On 25 July 2001, the Russian factory trawler Petropavlovsk was seized in the Bering Sea seven miles into the U. S. EEZ by the U. S. Coast Guard. There was approximately 75 metric tons of pink and chum salmon onboard that the captain claimed were purchased from the Russian coastal fishing fleet off the east coast of Kamchatka. Samples of both pink and chum salmon were analyzed using stock identification methods to determine whether they were of Asian or North American origin. The origins of the chum salmon samples were 92% Asian and 8% North American by the standard maximum likelihood (MLE) method, and 100% Asian by the Bayesian method. The origins of the pink salmon samples were 85% Asian and 15% North American by
the MLE method, and 99% Asian and 1% North American by the Bayesian method. Results of the analysis do not refute the F/V Petropavlovsk captainb??s statement that he purchased the salmon in Russian waters.
