This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes statewide Pacific salmon escapement goals in effect in 2022 and documents escapements for all species and stocks with goals from 2014 through 2022. Annual escapements are compared against escapement goals in place at the time to assess outcomes, with summaries by the Division of Commercial Fisheries regions. We list methods used to enumerate escapements and to develop current escapement goals (with brief descriptions) for each monitored stock. For the 2021–2022 Alaska Board of Fisheries meeting cycle, escapement goals were reviewed for the Southeast Region and Prince William Sound Management Area, which had been postponed from the 2020–2021 meeting cycle because of the COVID-19 pandemic. As a result of these reviews, there were 7 escapement goal changes for 2022. In the Southeast Region, 2 escapement goals were updated (1 coho and 1 sockeye salmon), and in Prince William Sound, 4 escapement goals were updated (2 coho and 2 sockeye salmon) and the Copper River Chinook salmon escapement goal was revised from a lower-bound SEG to an SEG with an upper and lower bound. The number of salmon escapement goals in Alaska remained at 264. In 2022, 67% of the escapement goals in Alaska were met or exceeded and 33% of the stocks did not meet minimum escapement goals.

Download or read book A Review of Escapement Goals for Salmon Stocks in Lower Cook Inlet Alaska 2023 written by Edward O. Otis and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alaska Department of Fish and Game (ADF&G) interdivisional escapement goal review committee (committee) reviewed 41 escapement goals for Pacific salmon Oncorhynchus spp. stocks in Lower Cook Inlet (LCI). Escapement goals were reviewed based on the Policy for the Management of Sustainable Salmon Fisheries (5 AAC 39.222) and the Policy for Statewide Salmon Escapement Goals (5 AAC 39.223) adopted by the Alaska Board of Fisheries into regulation in 2001. All of the existing goals were adopted in 2017, except for 1 chum salmon O. keta stock (McNeil River, adopted 2007) and 2 sockeye salmon O. nerka stocks (Bear and English Bay Lakes, adopted 2001). Except for 2 Chinook salmon O. tshawytscha stocks (Anchor and Ninilchik Rivers) and 4 sockeye salmon stocks (English Bay, Bear, Mikfik, and Chenik Lakes), salmon escapements in LCI are primarily monitored by single or multiple aerial and/or foot surveys of appropriate stream reaches. The resulting escapement indices do not provide absolute abundance estimates suitable for estimating biological escapement goals (BEG). Consequently, all LCI goals are sustainable escapement goals (SEG). There are no escapement goals for coho salmon O. kisutch in LCI. To improve management flexibility and consistency between management areas in Alaska, the committee supported LCI transitioning from stock-specific SEGs for pink (O. gorbuscha, 18 stocks) and chum (12 stocks) salmon to aggregate escapement goals for each of the 3 LCI districts with commercial fisheries targeting these species (Southern, Outer, and Kamishak). ADF&G will continue managing LCI Chinook (3 stocks) and sockeye (8 stocks) salmon using stock-specific SEGs, with 2 Chinook (Anchor and Ninilchik Rivers) and 2 sockeye salmon (Bear and English Bay Lakes) goals changing during this review period.

Download or read book Estimating Escapement of Western Alaskan Sockeye Salmon for Western Alaska Salmon Stock Identification Program Reporting Groups 2006 to 2008 written by Douglas Murrell Eggers and published by . This book was released on 2012 with total page 27 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 sockeye salmon. Escapements and associated uncertainties were estimated for each of the WASSIP sockeye salmon regional reporting groups (Chignik, South Peninsula, North Peninsula, Bristol Bay, Kuskokwim Bay), and subregional reporting groups (i.e., stocks). The 2006 to 2008 escapement estimates were based on information available in annual area management reports, other monitoring and assessment reports, and department databases.
Download or read book Yakutat Salmon Escapement Surveys 2022 2024 written by Richard A. Hoffman (Biologist) and published by . This book was released on 2022 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alaska Department of Fish and Game, Division of Commercial Fisheries, monitors annual spawning escapements of Pacific salmon within the Yakutat Management Area. Aerial and ground surveys are methods used to develop escapement estimates of sockeye Oncorhynchus nerka, Chinook O. Tshawytcha, and coho O. kisutch salmon. Inseason assessment of salmon runs plays an important role in the management of the Yakutat commercial, subsistence, and sport fisheries where harvest adjustments can be made in order to meet escapement goals. This report provides operational guidelines for the locations and methods for conducting systematic surveys for obtaining peak index counts of local salmon stocks.
Download or read book Alaska Peninsula Salmon Enumeration and Escapement Sampling Procedures 2023 2025 written by William S. Middleton and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Alaska Peninsula Management Area (Area M), weirs are a primary mode of enumeration for sockeye salmon Oncorhynchus nerka escapements into some area streams. Annually, the Alaska Department of Fish and Game (ADF&G) samples adult sockeye salmon escapements at the Nelson, Bear, Sandy, Ilnik, and Orzinski rivers, and McLees Lake for age, sex, and length (ASL) data. Out-migrating juvenile sockeye salmon (smolt) are also sampled for age, weight, and length (AWL) at Nelson, Bear, and Orzinski river weirs. The biological information collected from salmon escapements provide the foundation for preseason run forecasts, escapement goal evaluation, and accurate assignment of the run to stock-of-origin (run reconstruction) to some Alaska Peninsula systems. The use of this data assists with long-term management of sockeye salmon stocks while daily monitoring of the sockeye salmon escapements helps ensure that escapement goals are met. Operation guidelines for the six Area M ADF&G weir camps are presented, including weir installation instructions, salmon enumeration and sampling procedures, and general camp policies.

It describes the methods and results of the study, and explains how all study objectives have been met. With this report, Alaska Energy Authority has completed the field work, data collection and analysis, and reporting for this study. The objectives of this study were to radio-tag and track adults of five species of Pacific salmon from the lower to upper Susitna River, to characterize their migratory behavior and spawning behavior, to use sonar in turbid waters, to compare historical and current data, to count adult chinook salmon spawning, to collect tissue samples, and to estimate the salmon escapement of the Susitna River. The study area encompassed the Susitna River from its mouth at the Cook Inlet upstream to the confluence of the Oshetna River.
Download or read book Summary of Pacific Salmon Escapement Goals in Alaska with a Review of Escapements from 2012 to 2020 written by Andrew Roy Munro and published by . This book was released on 2021 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes statewide Pacific salmon escapement goals in effect in 2020 and documents escapements for all species and stocks with goals from 2012 through 2020. In addition, this report documents changes in escapement goals for both 2019 and 2020 because the report was not published in 2020 due to extenuating circumstances associated with the COVID-19 pandemic. Annual escapements are compared against escapement goals in place at the time to assess outcomes, with summaries by the Division of Commercial Fisheries regions. We list methods used to enumerate escapements and to develop current escapement goals (with brief descriptions) for each monitored stock. Leading up to the 2018/2019 Board of Fisheries meeting cycle, escapement goals were reviewed for the Bristol Bay, Arctic-Yukon-Kuskokwim, Alaska Peninsula/Aleutian Islands, and Chignik Management Areas. As a result of these reviews, there were 29 escapement goal changes in 2019, including the elimination of 10 goals. The remaining changes were due to updates to escapement indices and/or goal development methods. There were no changes to any escapement goals in the Chignik Management Area. For the 2019/2020 Board of Fisheries meeting cycle, escapement goals were reviewed for Upper Cook Inlet, Lower Cook Inlet, and Kodiak Management Areas. As a result of these reviews, there were 32 escapement goal changes in Upper Cook Inlet that included establishing 4 new escapement goals and eliminating 12 goals. There were no escapement goal changes for Lower Cook Inlet. Because of these revisions, there were 272 salmon escapement goals in Alaska in 2019 and 264 escapement goals in 2020. In 2019, 78% of the escapement goals in Alaska were met or exceeded and 22% of the stocks did not meet minimum escapement goals. In 2020, 65% of the escapement goals were met or exceeded and 35% of the stocks did not meet minimum escapement goals.
