Book Description
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 Klukshu River sockeye salmon (Oncorhynchus nerka) be designated as a “stock of management concern” in October 2020. 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.” Klukshu River sockeye salmon escapements have been below the lower bound of the current BEG range in 4 of the last 5 years, 2016–2020. Klukshu River is a tributary of the Alsek River and is entirely within Yukon, Canada. Klukshu River sockeye salmon are harvested primarily in a commercial set gillnet fishery that operates in the lower portions of the Alsek River and in Dry Bay in the U.S. and in a Champagne–Aishihik First Nation Aboriginal fishery that takes place in or near the Klukshu River in Canada. Alsek River salmon fisheries are managed under the provisions of the Pacific Salmon Treaty (PST) and management actions since 2018 have been designed to reduce harvest of Klukshu River sockeye salmon.

Book Description
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 Description
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.

Book Description
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.

Book Description
This report provides the Alaska Board of Fisheries with information on Yukon Area salmon stock status, including escapement and harvest data for the January 2023 regulatory meeting. In response to the guidelines established in the Policy for the Management of Sustainable Salmon Fisheries (5 AAC 39.222), the Alaska Board of Fisheries (board) classified the Yukon River Chinook salmon Oncorhynchus tshawytscha stock as a stock of yield concern at its September 2000 work session. An action plan was developed by the Alaska Department of Fish and Game and acted upon by the board in January 2001. The status as a yield concern was continued for Yukon River Chinook salmon at the January 2004, 2007, 2010, 2013, 2016, and 2019 board meetings. Chinook salmon escapement goal performance has been mixed throughout the past 5 years (2018–2022) throughout the Alaska portion of the Yukon River drainage, but escapement goals were not met from 2020 to 2022. Conservative management actions taken inseason have included full subsistence fishery closures to protect low runs as they migrate upriver. Additionally, Yukon River summer chum, fall chum O. keta, and coho salmon O. kisutch recently experienced a drastic decline since 2020. Most escapement goals for chum and coho salmon have not been achieved since 2020 despite significant subsistence, personal use, and commercial fishing restrictions and closures. Historically, the Yukon River chum and coho salmon stocks have met or exceeded escapement goals and provided for subsistence, personal use, and commercial fisheries, with a few exceptions of decreased production in a couple tributaries.

Book Description
The 2021 forecast of Stikine River sockeye salmon, Oncorhynchus nerka, run abundance is poor and we anticipate very little harvesting 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 migratory timing information that is used to complete the mixed stock run reconstruction for Stikine River sockeye salmon. It is highly likely there will be no fishing opportunity in 2021 to gather this pertinent information. To obtain stock composition data necessary to estimate the inriver abundance, we are initiating a sockeye salmon stock assessment program at Kakwan Point. The project will be conducted in conjunction with the existing Stikine River Chinook salmon, O. tshwaytscha, assessment program, and will extend the project through the end of the sockeye salmon run in late 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 catch per unit effort (CPUE) information and estimate the age, sex and length (ASL) composition for sockeye salmon captured. This stock assessment program is designed to capture sockeye salmon in proportion to abundance during immigration; therefore, it is expected that it will provide an unbiased estimate of abundance. This estimate will be assessed by TTC postseason for use in the Stikine River sockeye salmon run reconstruction.
