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
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 Description
The Crooked Creek Chinook Salmon Enhancement Project is designed to monitor both naturally- and hatchery-produced Chinook salmon escapements as well as collect brood stock and conduct egg takes to provide additional sport fishing opportunities within the Kasilof River and other terminal fisheries throughout Southcentral Alaska. This project imprints Chinook salmon smolt for 7 to 10 days at the beginning of June. Additionally, age, sex, and length samples will be collected from returning naturally- and hatchery-produced Chinook salmon. Currently, Crooked Creek has a sustainable escapement goal (SEG) of 700–1,400 naturally-produced ocean-age 2+ Chinook salmon. The overall goal of this research program is to reconstruct naturally- and hatchery-produced returns of Chinook salmon to Crooked Creek such that a biological escapement goal (BEG) can be established.

Book Description
This plan describes the coded-wire-tagging of juvenile Chinook salmon Oncorhynchus tshawytscha on the Unuk River for the 2021 and 2022 brood years, which covers the coded-wire-tagging of parr in fall of 2022 and 2023 and smolt in spring of 2023 and 2024, and sampling returning adults for age, sex, length, and coded wire tags in escapement from the 2024 through 2029 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 2022 and 2023. The primary goals of this and the companion study are to estimate inriver run size, total run size, marine harvest and exploitation rates, 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 to evaluate the Unuk River Chinook salmon escapement goal, and the Pacific Salmon Commission uses the data for coastwide management and stock assessment through the Chinook Technical Committee.

Book Description
The purpose of this project is to determine Chinook salmon Oncorhynchus tshawytscha harvest by sport anglers on the Situk River and the age components of that harvest. Additionally, sockeye salmon Oncorhynchus nerka harvest will be determined and various methods of angler use patterns for both species will be recorded. Creel sampling techniques will be used to collect catch, harvest, effort and biological information from the Situk River for this purpose. This information is used to manage for the Chinook salmon biological escapement goal for the Situk River as per the Situk-Ahrnklin and Lost River Chinook salmon Management Plan, along with achieving the Situk River sockeye salmon biological escapement goal. Inriver abundance for both Situk River Chinook and sockeye is obtained from another project with a fish weir, and escapement is calculated by subtracting the above-weir sport harvest estimate of this project from that weir count. Additionally, the Chinook salmon age component information of the harvest gathered here is required for yearly stock assessment models to predict the following years run and set preseason management regulations.

Book Description
The primary purpose of this study is to continue to update the spawning distribution and run timing of Chinook salmon in the Copper River drainage. These stock specific traits were previously estimated from 1999–2004, then again in 2019 and 2020. The purpose of this amendment is to formally acknowledge additional funding for a final year (2021) of the project through the ADF&G Operational Plan process. This amendment updates ROP.SF.3F.2019.04.

Book Description
The Deshka River is the largest producer and has the largest sport fishery of Chinook salmon in the North Cook Inlet Management Area. The Deshka River weir has operated seasonally since 1995. A floating, resistance-board-weir is used at river mile (RM) 7 to enumerate Chinook and coho salmon and to collect age, sex, and length data from these species. The Deshka River sustainable escapement goal (SEG) range is currently 9,000–18,000 fish for Chinook salmon and 10,200–24,100 fish for coho salmon. Data collected at this weir are used to manage sport and commercial fisheries inseason and to develop and evaluate escapement goals. This project is also used as a platform to collect harvest data upstream of RM 7, passage data of other fish species, environmental data, and it provides recapture data for the greater Susitna River drainage Chinook salmon mark–recapture project.
