Book Description
Sport anglers fishing from shore in the Juneau area of Southeast Alaska target and harvest Chinook salmon Oncorhynchus tshawytscha, primarily during April - August, the duration of which can be truncated due to wild stock management measures. Angler effort, catch, and harvest data will be collected from June through August 2022 from shore-based anglers at 2 prioritized locations in the Juneau area associated with Alaska hatchery release sites. Harvest sampling will be used to collect biological samples and associated data to estimate the age, length, and genetic composition of the Chinook salmon harvest. Chinook salmon will be inspected for missing adipose fins, indicating the head should be removed to recover a coded wire tag. Contributions of hatchery and wild coded-wire-tagged stocks to the sport harvest will be estimated for both locations.

Book Description
Sport-angler effort and harvest of Chinook salmon Oncorhynchus tshawytscha were estimated from a creel survey conducted at 2 distinct hatchery release sites along the Juneau shoreside from 1 June to 28 August 2022. This time period aligned with liberalized sport bag and possession limits targeting Alaska hatchery Chinook salmon production at a designated sport harvest hatchery area encompassing these 2 hatchery release sites as well as adjacent marine waters. Sport anglers harvested an estimated total of 2,628 Chinook salmon across both hatchery release areas, including 1,462 (SE = 207) at Macaulay Salmon Hatchery and 1,165 (SE = 259) at Fish Creek. The total Chinook salmon harvest observed at Macaulay Salmon Hatchery (1,462) included 1,383 (SE = 207) large and 80 (SE = 80) non-large fish. The total Chinook salmon harvest observed at Fish Creek (1,165) included 982 (SE = 221) large and 183 (SE = 55) non-large fish. Total effort (angler-hours) was estimated at 18,905, including 12,623 (SE = 629) at Macaulay and 6,282 (SE = 481) at Fish Creek. The stock composition based on genetic analysis revealed Chinook salmon harvested in these 2 distinct hatchery release areas were approximately 99% enhanced-origin fish from the Andrew Creek stock. Large Chinook salmon (defined as fish >28ʺ total length) dominated the total catch across both areas (approximately 84%). The age composition of large Chinook salmon harvested by sport anglers across both areas was dominated by age-1.3 fish (>80%). Residents comprised about 65% of all interviewed anglers.

Book Description
This project surveys the Chinook salmon sport fishery on the Naknek River. Information will be collected on angler-days of effort by type of angler (guided vs. unguided), catch and harvest rates of Chinook salmon, as well as age (from scales), sex, length, and weight of Chinook salmon in the sport harvest. Data collected from onsite surveys will be used to document angler use patterns and to design regulations that will accommodate growth in the sport fishery and maintain angling opportunity. Results will also guide review of current regulations and will be used to assess the effectiveness of current regulations.

Book Description
A creel survey will be conducted to estimate sport angler effort, catch, and harvest of large (≥75 cm mid eye to tail fork length) early- and late-run Chinook salmon in the lower Kenai River between the Warren Ames Bridge (river mile [RM] 5.1) and Slikok Creek sanctuary area (RM 18.6). Creel survey estimates will be geographically stratified in relation to the RM 13.7 Kenai River Chinook salmon sonar to provide angler effort, catch, and harvest of large Chinook salmon. A standardized inriver netting project will be conducted in the Kenai River at RM 8.6 to index abundance and estimate the age, sex, and length (ASL) composition of large early- and late-run Chinook salmon. Inseason estimates of Chinook salmon catch and harvest, used in conjunction with sonar passage estimates, inseason catch rates, and the length of returning Chinook salmon from the inriver netting study are used by fisheries managers for inseason management decisions to achieve escapement goals. This plan covers the creel survey and inriver netting studies for the 2021–2023 seasons.

Book Description
The Crooked Creek Chinook Salmon Enhancement Project is designed to monitor both naturally- and hatchery-produced Chinook salmon (Oncorhynchus tshawytscha) escapement as well as collect broodstock and conduct egg takes to provide additional sport fishing opportunities within the Kasilof River and other terminal fisheries on the Kenai Peninsula. This project will imprint Chinook salmon smolt for 7 to 10 days at the beginning of June. Additionally, age, sex, and length, will be collected from returning naturally- and hatchery-produced Chinook salmon. The sustainable escapement goal for Crooked Creek is 700–1,400 naturally-produced 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
An ongoing coded-wire tag project, used as part of a stock assessment program for Chilkat River Chinook salmon Oncorhynchus tshawytscha and coho salmon Oncorhynchus kisutch, will be conducted during fall 2020 and spring 2021 to provide estimates of smolt abundance and marine harvest for Chinook and coho salmon. This project uses modified Peterson 2-event mark-recapture methods to estimate smolt abundance, and port and creel sampling of coded-wire tags in mixed stock commercial and sport fisheries to estimate marine harvest for both species. Juvenile salmon will be measured for length and weight, marked with adipose fin clips, and tagged with coded wire tags in fall 2020 (juvenile Chinook salmon) and spring 2021 (Chinook and coho salmon smolt) as event 1 of the mark-recapture study. During event 2, adult Chinook salmon will be sampled for missing adipose fins, coded wire tags, age, sex, and length in Chilkat River fishwheels and drift gillnets, which are operated in the lower Chilkat River as part of a separate adult mark-recapture project. Adult Chinook salmon will be also sampled for missing adipose fins, coded wire tags, and age, sex, and length during Chilkat River drainage spawning grounds surveys to complete event 2 sampling. Coho salmon will also be sampled as adults during event 2 in the lower Chilkat River fishwheels. Age composition of Chinook salmon adults will be estimated by scale ageing techniques; age composition of coho salmon smolt and adults will also be estimated. The Alaska Department of Fish and Game uses these data to make local and regional management decisions. Chilkat Chinook salmon is a Pacific Salmon Commission exploitation rate and escapement indicator stock and has recently been added to the base model of abundance indicator stocks for the Chinook Technical Committee, which influences coastwide management.
