Download or read book Harvest and Harvest Rates of Chum Salmon Stocks in Fisheries of the Western Alaska Salmon Stock Identification Program (WASSIP), 2007-2009 written by Andrew Roy Munro and published by . This book was released on 2012 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: Uncertainty about the magnitude, frequency, location, and timing of stock-specific sockeye and chum salmon harvest in western Alaska fisheries was the impetus for the Western Alaska Salmon Stock Identification Program (WASSIP). The program was designed to use genetic data in mixed stock analysis (MSA) of fisheries samples to more clearly describe harvest patterns of sockeye and chum salmon stocks in western Alaska fisheries. This report reviews the history of WASSIP, summarizes the memorandum of understanding as the guiding document for the program, and reviews participation and contributions of the Advisory Panel and Technical Committee to the program. Brief descriptions of WASSIP sockeye fisheries are provided and previous sockeye tagging and stock identification studies are reviewed. We describe the methodology used to estimate stock-specific harvests and harvest rates for sockeye salmon, report these estimates, and provide guidance on interpretation of results. These results provide the most comprehensive examination of stock-specific harvest and harvest rates across western Alaska sockeye salmon fisheries ever attempted.

Templin and published by . This book was released on 2012 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Uncertainty about the magnitude, frequency, location, and timing of stock-specific sockeye and chum salmon harvest in western Alaska fisheries was the impetus for the Western Alaska Salmon Stock Identification Program (WASSIP). The program was designed to use genetic data for mixed stock analysis (MSA) of fisheries samples to more clearly describe harvest patterns of chum and sockeye salmon stocks in western Alaska fisheries. Stock composition estimates for temporal strata across fisheries are required to estimate stock-specific harvest numbers and rates. This report describes the methods used to estimate stock compositions for chum salmon, presents stock composition estimates, and provides guidance on how to interpret biases documented in MSA baseline tests when evaluating stock composition estimates of WASSIP catch samples.
Book Synopsis Genetic Stock Composition of Chum Salmon Harvested in Commercial Salmon Fisheries of the South Alaska Peninsula, 2022-2026 by : M. Birch Foster
Download or read book Genetic Stock Composition of Chum Salmon Harvested in Commercial Salmon Fisheries of the South Alaska Peninsula, 2022-2026 written by M. Birch Foster and published by . This book was released on 2022 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary goal of this study is to use mixed stock analysis to estimate the stock composition of chum salmon Oncorhynchus keta harvested in South Alaska Peninsula Management Area (southern portion of Area M) commercial salmon fisheries during the 2022 to 2026 seasons. Relatively large harvests of chum salmon in South Alaska Peninsula fisheries in recent years corresponding with small returns of chum salmon to Western Alaska rivers has raised concerns among some stakeholders about the stock-specific harvests in South Alaska Peninsula fisheries. Salmon tagging studies published in 1926, 1964, and 1991 and subsequent genetic stock identification projects conducted in 1993-1996 and 2007-2009 demonstrated significant numbers of non-local chum salmon in the June and early July commercial fisheries of the South Alaska Peninsula. Presently, some stakeholders believe that relative abundances among stocks in the fishery have changed since stock-specific chum harvests were last estimated in South Alaska Peninsula harvests as part of the Western Alaska Salmon Stock Identification Program (WASSIP) in 2007-2009. An updated study that accurately and precisely estimates stock-specific harvests would help resolve these concerns and provide valuable management information regarding the gear- and temporal-specific harvests of chum salmon in select South Peninsula fisheries. This operational plan provides the Alaska Department of Fish and Game (ADF&G) with a sampling and genetic analysis plan to achieve that overall goal.

Book Synopsis Estimating Escapement of Western Alaska Chum Salmon for Western Alaska Salmon Stock Identification Program Reporting Groups, 2007 to 2009 by : Douglas Murrell Eggers
Download or read book Estimating Escapement of Western Alaska Chum Salmon for Western Alaska Salmon Stock Identification Program Reporting Groups, 2007 to 2009 written by Douglas Murrell Eggers and published by . This book was released on 2012 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Western Alaska Salmon Stock Identification Program (WASSIP) was initiated in 2006 with a memorandum of understanding executed by an Advisory Panel of 11 signatories, including Alaska Department of Fish and Game, and stakeholders from throughout western Alaska. The purpose of WASSIP was to identify stock contributions of sockeye (Oncorhynchus nerka) and chum salmon (O. keta) to commercial and subsistence fisheries from Chignik northward to Kotzebue Sound, and to extend those estimates to stock-specific harvest rates. This report describes the regional fishery model and estimation of escapement and harvest rates for chum salmon. Escapements and associated uncertainties were estimated for each of the WASSIP chum salmon regional reporting groups (Chignik/Kodiak, South Peninsula, Northwest District, Northern District, Coastal Western Alaska, Upper Yukon River, Kotzebue Sound; i.e., stocks). The 2007 to 2009 escapement estimates were based on information available in annual area management reports, other monitoring and assessment reports, and department databases.

Book Synopsis Chum Salmon Baseline for the Western Alaska Salmon Stock Identification Program by : Nicholas A. Decovich
Download or read book Chum Salmon Baseline for the Western Alaska Salmon Stock Identification Program written by Nicholas A. Decovich and published by . This book was released on 2012 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Uncertainty about the magnitude, frequency, location, and timing of the nonlocal harvest of sockeye and chum salmon was the impetus for the Western Alaska Salmon Stock Identification Program. The program was designed to use genetic data in mixed stock analysis to reduce this uncertainty. A baseline of allele frequencies in spawning populations is required for use in mixed-stock analysis to estimate the stock of origin of harvested fish. This report describes the methodology used to understand the population genetic structure among chum salmon populations and to build and test a baseline for use in mixed stock analysis of chum salmon. Of the 35,921 fish from 434 collections selected to be genotyped, the final baseline was composed of 32,817 fish from 402 collections representing 310 populations. Average population sample size was 106 fish. Reporting groups were determined through a combination of stakeholder needs and identifiability using genetic information, as measured using proof tests. The final reporting groups included Asia, Kotzebue Sound, Coastal Western Alaska, Upper Yukon River, Northern District (Alaska Peninsula), Northwest District (Alaska Peninsula), South Peninsula (Alaska Peninsula), Chignik/Kodiak, and East of Kodiak.

Book Synopsis Chum Salmon Stock Status and Escapement Goals in Southeast Alaska by : Andrew W. Piston
Download or read book Chum Salmon Stock Status and Escapement Goals in Southeast Alaska written by Andrew W. Piston and published by . This book was released on 2017 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Southeast Alaska, chum salmon (Oncorhynchus keta) spawn in more than 1,200 streams. The Alaska Department of Fish and Game maintains a standardized survey program to index spawning chum salmon abundance at 87 summer-run and seven fall-run streams. Lower-bound sustainable escapement goals are established for summer-run stocks comprising aggregates of index streams over three broad subregions (Southern Southeast, Northern Southeast Inside, and Northern Southeast Outside) and sustainable escapement goal ranges are established for five fall-run stocks that support directed fisheries (Cholmondeley Sound, Port Camden, Security Bay, Excursion River, and Chilkat River). We reviewed chum salmon escapement goals and recommend that summer-run chum salmon goals continue to be based on the 25th percentiles of historical escapement index counts, primarily due to the uncertainty regarding harvest rates. We recommend reducing the Northern Southeast Inside Subregion lower-bound sustainable escapement goal from 119,000 to 107,000 fish. For fall-run chum salmon stocks, except for the Chilkat River, we also recommend continuing to base escapement goals on the 25th and 75th percentiles of historical escapement index counts, and recommend no changes at this time. Summer-run chum salmon escapement goals were met in four of the past five years in the Southern Southeast and Northern Southeast Outside subregions, and in three of the past five years in the Northern Southeast Inside Subregion. Escapement goals were met for the five fall-run stocks 84% of the time over the past 5 years. The annual common property harvest of chum salmon in Southeast Alaska averaged 6.9 million fish per year since 2007; hatchery-produced fish accounted for an average 85% of that harvest. No Southeast Alaska stocks of chum salmon currently meet the criteria for stocks of concern as defined by the State of Alaska's Policy for Management of Sustainable Salmon Fisheries (5 AAC 39.222).
Book Synopsis Norton Sound Subdistrict 1 (Nome) Chum Salmon Stock Status and Action Plan, 2010 by : Jim Menard
Download or read book Norton Sound Subdistrict 1 (Nome) Chum Salmon Stock Status and Action Plan, 2010 written by Jim Menard and published by . This book was released on 2009 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to guidelines established in the Policy for the Management of Sustainable Salmon Fisheries (SSFP; 5 AAC 39.222), the Alaska Board of Fisheries (BOF) classified the Norton Sound Subdistrict 1 (Nome) chum salmon Oncorhynchus keta stock as a stock of management concern at its September 2000 work session. An action plan was developed by the Alaska Department of Fish and Game (ADF&G) and acted upon by the BOF in January 2001. The SSFP directs ADF&G to assess salmon stocks in areas addressed during the BOF regulatory cycle to identify stocks of concern and, in the case of Subdistrict 1 chum salmon, to reassess the stock of concern status. In 2003, ADF&G recommended continuation of this classification as a stock of management concern, which was supported by the BOF at its January 2004 meeting. A majority of chum salmon escapement goals were achieved in Subdistrict 1 from 2002-2006. Hence, in January 2007, the BOF classified Subdistrict 1 chum salmon stock of yield concern. Since 2004, escapement has been met in Subdistrict 1, except for 2009, when it fell 7% short of the lower end of the escapement goal range of 23,000-35,000. The recent yield remains below historical levels despite use of specific management measures. Based on the definitions provided in the SSFP, ADF&G recommends continuing the stock of concern classification of Subdistrict 1 chum salmon as a stock of yield concern. The department recommends that management continue under the current plans through the next board cycle.
Book Synopsis Norton Sound Nome Subdistrict Chum Salmon Stock Status and Action Plan, 2007 by : Jim Menard
Download or read book Norton Sound Nome Subdistrict Chum Salmon Stock Status and Action Plan, 2007 written by Jim Menard and published by . This book was released on 2006 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to the guidelines established in the Policy for the Management of Sustainable Salmon Fisheries (SSFP; 5 AAC 39.222), the Alaska Board of Fisheries (BOF) classified the Norton Sound Nome Subdistrict (Subdistrict 1) chum salmon Oncorhynchus keta stock as a stock of management concern at the September 2000 work session. A "management concern" is defined as, "a concern arising from a chronic inability, despite use of specific management measures, to maintain escapements for salmon stocks within the bound of Sustainable Escapement Goal (SEG), Biological Escapement Goal (BEG), Optimal Escapement Goal (OEG), or other specified objectives for the fishery." An action plan was developed by the Alaska Department of Fish and Game (ADF&G) and acted upon by the BOF in January 2001. The SSFP directs ADF&G to assess salmon stocks in areas addressed during the BOF regulatory cycle to identify stocks of concern and in the case of Nome Subdistrict chum salmon, to reassess the stock of concern status. In 2003, the department recommended continuation of this classification as a stock of management concern, which was supported by the BOF at its January 2004 meeting. Since that time, a majority of chum salmon escapement goals were achieved in the Nome Subdistrict from 2002 to 2006. Hence, the Nome Subdistrict chum salmon stock no longer meets the definition for a management concern as defined in SSFP. However, the recent yield remains well below historical levels despite use of specific management measures. Based on the definitions provided in the SSFP, ADF&G recommends changing the stock of concern classification of the Nome Subdistrict chum salmon stock from a management concern to a yield concern. The department recommends that management continue under the current plans through the next board cycle.
Book Synopsis Genetic Stock Composition Analysis of Chum Salmon Bycatch Samples from the 2008 Bering Sea Groundfish Fisheries by : Andrew Karl Gray
Download or read book Genetic Stock Composition Analysis of Chum Salmon Bycatch Samples from the 2008 Bering Sea Groundfish Fisheries written by Andrew Karl Gray and published by . This book was released on 2011 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Yukon River Fall Chum Salmon Stock Status and Fall Season Salmon Fisheries by : Fred J. Bue
Download or read book Yukon River Fall Chum Salmon Stock Status and Fall Season Salmon Fisheries written by Fred J. Bue and published by . This book was released on 2006 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to the guidelines established in the Policy for the Management of Sustainable Salmon Fisheries (SSFP; 5 AAC 39.222), the Alaska Board of Fisheries (BOF) classified the Yukon River fall chum salmon Oncorhynchus keta stock as a yield concern and classified the Toklat and Fishing Branch Rivers fall chum salmon stocks as management concerns at the September 2000 work session. An action plan was developed by the Alaska Department of Fish and Game (ADF & G) and acted upon by the BOF in January 2001. The SSFP directs ADF & G to assess salmon stocks in areas addressed during the BOF regulatory cycle to identify stocks of concern and to reassess the stock of concern status. In 2003, the department recommended continuation of the Yukon River fall chum salmon classification as a stock of yield concern, which was supported by the BOF at its January 2004 meeting. The Toklat River stock was removed as a management concern because the BOF realigned the escapement objective from an optimal escapement goal (OEG) to the established biological escapement goal (BEG) which did not fit the criteria of a management concern. However, the Toklat River fall chum salmon stock was included in the drainage-wide yield concern classification. The Fishing Branch River stock was also removed as a management concern because management of that portion of the drainage is covered by an annex to the Pacific Salmon Treaty, the U.S./Canada Yukon River Salmon Agreement (Agreement) which is governed under the authority of the Yukon River Panel (Panel). Based on the much improved run size since 2002 and large available surpluses in 2003, 2005 and 2006 being near the historical yield, the Yukon River fall chum salmon stock no longer meets the stock of yield concern criteria. Therefore, ADF & G recommends the Yukon River fall chum salmon stock no longer be considered as a stock of concern. BEGs for fall chum salmon and the Yukon River Drainage Fall Chum Salmon Management Plan were both reviewed and updated at the January 2004 BOF meeting. Escapement and harvest monitoring projects are in place to aid in managing for sustained yield objectives. Proposal 173 has been submitted to the BOF for considering changes to the Yukon River Coho Salmon Management Plan to coordinate management of the overlapping fall chum and coho salmon fisheries.

Download or read book Chum Salmon Stock Status and Escapement Goals in Southeast Alaska Through 2019 written by Andrew W. Piston and published by . This book was released on 2020 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Southeast Alaska, chum salmon (Oncorhynchus keta) spawn in more than 1,200 streams. The Alaska Department of Fish and Game maintains a standardized survey program to index spawning chum salmon abundance at 87 summer-run and seven fall-run streams. Lower-bound sustainable escapement goals are established for summer-run stocks comprising aggregates of index streams over three broad subregions (Southern Southeast, Northern Southeast Inside, and Northern Southeast Outside), and sustainable escapement goal ranges are established for five fall-run stocks that support directed fisheries (Cholmondeley Sound, Port Camden, Security Bay, Excursion River, and Chilkat River). Summer-run chum salmon escapement goals were met in all of the past five years in the Southern Southeast Subregion, four of the past five years in the Northern Southeast Inside Subregion, and three of the past five years in the Northern Southeast Outside Subregion. Escapement goals were met for the five fall-run stocks 83% of the time over the past five years. No Southeast Alaska stocks of chum salmon currently meet the criteria for stocks of concern as defined by the State of Alaska’s Policy for the Management of Sustainable Salmon Fisheries (5 AAC 39.222). We reviewed chum salmon escapement goals and recommend no changes at this time. The annual common property harvest of chum salmon in Southeast Alaska averaged 7.7 million fish per year since 2010; hatchery-produced fish accounted for an average 86% of that harvest. Increased straying of hatchery chum salmon into streams in the Northern Southeast Outside Subregion from a new release site at Crawfish Inlet has complicated the assessment of wild chum salmon in that subregion and additional sampling is needed to determine the variation and geographic extent of straying from the new release site.
