This book was released on 2022 with total page 0 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), the Alaska Department of Fish and Game (department) recommended that the Stikine River and Andrew Creek stocks of Chinook salmon (Oncorhynchus tshawytscha) be designated as stocks of “management concern.” A management concern is defined as “a concern arising from a chronic inability, despite use of specific management measures, to maintain escapements for a salmon stock within the bounds of the SEG [sustainable escapement goal], BEG [biological escapement goal], OEG [optimum escapement goal], or other specified management objectives for the fishery.” Escapements of Stikine River Chinook salmon have fallen below the lower bound of the existing BEG (14,000 to 28,000 fish) each of the last 5 years (2016 to 2020). Since 2016, the department has implemented conservative management measures that have been effective in reducing the harvest of Stikine River Chinook salmon. Andrew Creek is a tributary to the Stikine River located entirely within Alaska. Chinook salmon escapements to Andrew Creek have been below the BEG (650 to 1,500 fish) in 4 of the previous 5 years. It is assumed actions that have reduced the harvest of Stikine River Chinook salmon have also reduced harvest of Andrew Creek Chinook salmon.

Available in PDF, EPUB and Kindle. Book excerpt: In response to guidelines established in the Policy for the Management of Sustainable Salmon Fisheries (SSFP), the Alaska Department of Fish and Game (department) recommended that the Unuk River stock of Chinook salmon (Oncorhynchus tshawytscha) be designated as a “stock of management concern” in October 2017. This recommendation was adopted by the Alaska Board of Fisheries (board) in January 2018. Then, in October 2020, the department recommended continuing this designation and additionally recommended that the Chickamin River stock of Chinook salmon be added as a “stock of management concern”. A “management concern” is defined as “a concern arising from a chronic inability, despite use of specific management measures, to maintain escapements for a salmon stock within the bounds of the SEG [sustainable escapement goal], BEG [biological escapement goal], OEG [optimum escapement goal], or other specified management objectives for the fishery.” The escapement of the Unuk River stock of Chinook salmon has been below the lower bound of the existing BEG (1,800–3,800 fish) in 3 of the past 5 years (2016–2020). The escapement of Chickamin River Chinook salmon has been below the lower bound of the existing BEG (2,150–4,300 fish) in 4 of the past 5 years (2016–2020). Since 2014, the department has implemented conservative management actions to reduce harvest of Unuk River Chinook salmon, and by extension and proximity to the Unuk River, it is assumed those actions have reduced harvests of Chickamin River Chinook salmon as well.

Download or read book Northern Southeast Alaska Chinook Salmon Stock Status and Action Plan, 2022 written by Grant Hagerman and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Escapements of Chinook salmon have fallen below the lower bound of the current BEG range for Chilkat River in 3 of the past 5 years, for King Salmon River in 4 of the past 5 years, and for the Taku River in 5 of the past 5 years. In response to guidelines established in the Policy for the management of sustainable salmon fisheries (SSFP), the Alaska Department of Fish and Game (department) recommended the Chilkat and King Salmon River Chinook salmon (Oncorhynchus tshawytscha) stocks be designated as stocks of “management concern” in 2017 followed by approval from the Alaska Board of Fisheries at the 2018 Southeast and Yakutat Finfish and Shellfish meeting. In October 2020, the department recommended the continuation of stock of management concern status for the Chilkat and King Salmon Rivers and to add the Taku River Chinook salmon stock at 2021 Southeast Alaska and Yakutat meeting. A “management concern” is defined as “a concern arising from a chronic inability, despite use of specific management measures, to maintain escapements for a salmon stock within the bounds of the SEG [sustainable escapement goal], BEG [biological escapement goal], OEG [optimum escapement goal], or other specified management objectives for the fishery.” Since 2012, the department has implemented conservative management measures to reduce the harvest of the Chilkat River stock of Chinook salmon and increase escapement. Through these measures, and from actions taken to reduce the harvest of the Taku River stock of Chinook salmon, by extension, harvest on the stock of Chinook salmon from the King Salmon River may likewise have been reduced. Although these management actions have been effective at reducing overall harvest rates, the poor runs have been so low that achievement of BEGs has been problematic.

Book Synopsis Spawning Escapement of Chinook Salmon in the Stikine River, 2022–2024 by : Kristin Courtney
Download or read book Spawning Escapement of Chinook Salmon in the Stikine River, 2022–2024 written by Kristin Courtney and published by . This book was released on 2022 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inriver abundance of large (fish =660 mm mid eye to tail fork [METF] length) Chinook salmon Oncorhynchus tshawytscha above the U.S./Canada border (border) will be estimated annually from 2022 to 2024 in the Stikine River, near Wrangell, Alaska. A modified Petersen 2-event mark–recapture project will be conducted using drift gillnets to mark large Chinook salmon in the first event, and collection of samples in the Canadian commercial fishery, Little Tahltan River video weir, and on the spawning grounds will serve as the second event. Additional project objectives are to a) estimate the annual spawning escapement of large Chinook salmon above the border, b) estimate the age, sex, and length composition of both the inriver run and spawning escapement, and c) estimate the proportion of large radiotagged Chinook salmon that cross the border. The Alaska Department of Fish and Game (ADF&G) and Fisheries and Oceans Canada (DFO) use these data to make terminal and regional management decisions, and the Pacific Salmon Commission (PSC) uses the data for coastwide management and stock assessment through the Chinook Technical Committee (CTC 2021).

Book Synopsis Inriver Abundance of Stikine River Sockeye Salmon, 2022-2024 by : Kristin Courtney
Download or read book Inriver Abundance of Stikine River Sockeye Salmon, 2022-2024 written by Kristin Courtney and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2022 forecast of Stikine River sockeye salmon, Oncorhynchus nerka, run abundance is poor and we anticipate very little harvest opportunity for either U.S. or Canadian fisheries. Since 1994, we have almost exclusively relied on the Canadian lower river commercial fishery to provide the stock-specific information that is used to complete the mixed stock run reconstruction for Stikine River sockeye salmon. It is highly likely there will be little commercial fishing opportunity in 2022 to gather this pertinent information. To obtain stock composition data necessary to estimate the inriver abundance, we will continue to conduct a sockeye salmon stock assessment program at Kakwan Point that began in 2021. The project will be conducted in conjunction with the existing Stikine River Chinook salmon, O. tshwaytscha, stock assessment program, and will extend the project through the end of the sockeye salmon run in mid-August. Tissue samples will be collected from sockeye salmon for genetic mixed stock analysis and for use in a genetic mark–recapture study to estimate inriver abundance based on an expansion of the Tahltan stock that is monitored via weir. We will also gather daily CPUE information, capture and spaghetti tag sockeye salmon, and estimate the age, sex, and length composition for sockeye salmon captured at Kakwan Point.

Book Synopsis Estimation of Smolt Production and Harvest of Stikine River Chinook Salmon, 2022-2024 by : Kristin Courtney
Download or read book Estimation of Smolt Production and Harvest of Stikine River Chinook Salmon, 2022-2024 written by Kristin Courtney and published by . This book was released on 2022 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary goals of this study are to estimate a) the number of Chinook salmon Oncorhynchus tshawytscha smolt (=50 mm FL) leaving the Stikine River yearly from 2022 to 2024, and b) the mean length and weight of Chinook salmon smolt leaving the Stikine River annually. Additional objectives include estimating the marine harvest and marine survival of adult Chinook salmon returning to the Stikine River from the 2020–2022 brood years and estimating the length and weight of coho salmon Oncorhynchus kisutch smolt that are captured during their outmigration. A modified Petersen 2-event mark–recapture project will be conducted to estimate smolt abundance, and a coded wire tag (CWT) project relying on harvest sampling programs will be conducted to estimate harvest. Length and weight data will be collected during the CWT and event 1 smolt tagging project. Chinook salmon smolt will be marked with adipose fin clips and CWTs each spring. Marked fish will be recaptured through creel, port, and escapement sampling procedures. The Stikine River is 1 of 12 statewide Chinook salmon indicator stocks monitored by the Alaska Department of Fish and Game (ADF&G) and is both an escapement and exploitation indicator stock for the Pacific Salmon Commission (Chinook Research Team 2013, CTC 2021). ADF&G and Fisheries and Oceans Canada (DFO) use these data, along with adult escapement information (described in a separate operational plan), to make terminal and regional management decisions, and the PSC uses these data for coastwide management and stock assessment through the Transboundary and Chinook Technical Committees.
Book Synopsis Local and Traditional Knowledge of Stikine River Chinook Salmon by : Joshua T. Ream
Download or read book Local and Traditional Knowledge of Stikine River Chinook Salmon written by Joshua T. Ream and published by . This book was released on 2017 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Alaska, statewide declines of Chinook salmon led to the development of the Chinook Salmon Research Initiative--a program aimed at better understanding these declines. Among the indicator stocks chosen for this study was the Stikine River in Southeast Alaska. This watershed is a dynamic system that influences the lives of people in Canada and Alaska, both contemporarily and since time immemorial. Its salmon runs support commercial, sport, and subsistence harvest activities. While American and Canadian entities have long studied Stikine River Chinook salmon stocks to affect improved management, rarely has Local and Traditional Knowledge (LTK) of these stocks been compiled and analyzed alongside of Western science and management. This study reports on LTK shared by commercial, sport, and subsistence users of Chinook salmon in Wrangell and Petersburg, Alaska. The knowledge, perceptions, and observations of these fishers provides stakeholder perspective on the Stikine River's Chinook salmon, their habitats, human consumption, economics, and fisheries management over time. This information may help to better inform the study and management of Chinook salmon in this important transboundary river.
