This book was released on 2016 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent reductions in the run sizes of Chinook Salmon Oncorhynchus tshawytscha in Southeast Alaska have resulted in social and economic hardships within the region. Pacific salmon yearclass strength may be determined by size-selective processes during the early marine phase of their life cycle; however, the relative importance of growth during freshwater and marine residence in determining recruitment success is unknown. A scale-based retrospective analysis was conducted to examine the effects of freshwater and annual marine growth and early marine conditions on survival to reproductive maturity for female Chinook Salmon by brood year (BY) in the Taku (BYs 1979 – 1985, 1990 – 1999, 2002 – 2004) and Unuk (BYs 1981 – 1983, 1986 – 1988, 1994 – 2003, 2005 – 2006) rivers. First-year marine growth was positively related to survival and total return for Chinook Salmon stocks from both systems. Growth during freshwater residence (i.e., size-at-ocean entry) was not related to survival or total return of either stock. In addition, there was a positive relationship between marine survival of Unuk River Chinook Salmon and sea-surface temperatures in Upper Chatham Strait, Icy Strait, and Auke Bay Monitor (P = 0.04) during early marine residence. The results of my research highlight the importance of growth and marine conditions during the first year at sea in determining the survival of Chinook Salmon in Southeast Alaska and suggest that current declines in run sizes and survival of stocks within this region may be the attributed to poor growth conditions or growth during early marine residence.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
