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
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 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 plan describes the coded-wire tagging of juvenile Chinook salmon Oncorhynchus tshawytscha on the Unuk River for the 2019 and 2020 brood years, which covers the coded-wire tagging of parr in fall of 2020 and 2021 and smolt in spring of 2021 and 2022, and sampling returning adults for age, sex, length, and coded-wire tags in escapement from the 2022 through 2027 return years. This study provides estimates of smolt and parr abundance, overwinter (freshwater) survival, mean lengths of juveniles, and harvest information of Chinook salmon originating from the Unuk River in Southeast Alaska. A separate project will be conducted on the Unuk River that employs aerial and foot survey peak counts to estimate large (≥660 mm mid eye to fork of tail length) adult Chinook salmon returning to the river in 2020 and 2021. The primary goals of this and the companion study are to estimate inriver run size, total run size, marine harvest-exploitation rate and harvest distribution, smolt and parr abundance, marine survival (smolt to adult) and overwinter survival (parr to smolt). The Alaska Department of Fish and Game uses this information to make local and regional management decisions, and the Pacific Salmon Commission uses the data for coastwide management and stock assessment through the Chinook Technical Committee.

Book Description
Estimates of Chinook salmon Oncorhynchus tshawytscha spawning escapement in 2022 will be summarized for 11 Southeast Alaska river systems: Situk River, Alsek River, Chilkat River, Taku River, King Salmon River, Stikine River, Unuk River, Chickamin River, Blossom River, Keta River, and Andrew Creek. Spawning escapements will be estimated using aerial surveys, foot surveys, mark–recapture studies, and weirs. The Alaska Department of Fish and Game and Fisheries and Oceans Canada use these data, along with age composition data to make terminal and regional management decisions, and the Pacific Salmon Commission uses these data for coastwide management and stock assessment.
