Book Description

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
This plan describes the coded-wire tagging of juvenile Chinook salmon Oncorhynchus tshawytscha on the Unuk River for the 2017 and 2018 brood years, which covers the coded-wire tagging of parr in fall of 2018 and 2019 and smolt in spring of 2019 and 2020, and sampling returning adults for age, sex, length, and coded-wire tags in escapement from the 2020 through 2025 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 2018 and 2019. 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).

Book Description
Reports on the results of a two-event mark-recapture experiment, which was used to estimate the abundance of Chinook salmon Oncorhynchus tshawytscha that returned to spawn in the Unuk River in 2009.

Book Description
Results of a study of the biological escapement goal for Chinook salmon, Oncorhynchus tshawytscha, from the Taku River. This study was investigated with information from a stock assessment program (1973-2007), catch sampling programs of the Canadian inriver gillnet fishery, the U.S. commercial gillnet fishery in Taku Inlet, the troll fishery in Southeast Alaska, and the U.S. recreational fishery near Juneau.
