Book Synopsis Stock Specific Abundance and Run Timing of Chinook Salmon in the Kenai River, 2007-2012 by : Adam M. Reimer
Download or read book Stock Specific Abundance and Run Timing of Chinook Salmon in the Kenai River, 2007-2012 written by Adam M. Reimer and published by . This book was released on 2016 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: A stock-specific abundance and run timing model (SSART) was fit to relative and absolute estimates of abundance, genetic stock identification data, radiotelemetry data, and creel survey estimates of harvest for Kenai River Chinook salmon (Oncorhynchus tshawytscha) from 2007 to 2012. Bayesian statistical methods were employed to estimate inriver abundance and run timing by stock at river mile 8.6 of the Kenai River. Abundance of early-run Chinook salmon ranged from 6,739 (SE 819) in 2012 to 12,300 (SE 2,087) in 2007. Abundance of late-run Chinook salmon ranged from 22,190 (SE 3,815) in 2010 to 48,370 (SE 8,641) in 2007. Tributary stocks had greater relative abundance within the run before 15 June and the Mainstem-Juneau Creek stock had greater relative abundance after 15 June. Fish from Killey River–Benjamin Creek, Funny River-Slikok Creek, and Quartz-Crescent creeks migrated upstream primarilyduring the first 3 of 6 time strata; fish from Grant Creek and Russian River migrated upstream primarily during the third through fifth time strata; and fish from Mainstem Kenai River-Juneau Creek migrated upstream primarily during the last 3 time strata.

Download or read book Stock-specific Abundance and Run Timing of Chinook Salmon in the Kenai River, 2007-2014 written by Adam M. Reimer and published by . This book was released on 2017 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: A stock-specific abundance and run timing model (SSART) was fit to relative and absolute estimates of abundance, genetic stock identification data, radiotelemetry data, and estimates of harvest for Kenai River Chinook salmon (Oncorhynchus tshawytscha) from 2007 to 2014. The methods follow a model of the 2007-2012 data except that inference is restricted to Chinook salmon 75 cm mid eye to tail fork (METF) or longer for all results in this report. Bayesian statistical methods were employed to estimate inriver abundance and run timing by stock at river mile 8.6 of the Kenai River. Abundance of early-run Chinook salmon ranged from 1,940 (SE 307) in 2013 to 8,637 (SE 2,215) in 2007. Abundance of late-run Chinook salmon ranged from 9,949 (SE 2,138) in 2010 to 37,180 (SE 10,340) in 2007. Fish from Killey River-Benjamin Creek, Funny River-Slikok Creek, and Quartz-Crescent creeks migrated upstream primarily prior to 30 June; fish from Grant Creek and Russian River migrated upstream primarily between 16 June and 31 July; and fish from Mainstem Kenai River-Juneau Creek migrated upstream primarily after 16 June. Tributary stocks had greater relative abundance within the run before 16 June and the Mainstem-Juneau Creek stock had greater relative abundance after 30 June. Between 16 June and 30 June, tributary stocks had greater relative abundance in 6 of 8 years while Mainstem-Juneau Creek fish had greater relative abundance in the other 2 years.

Book Synopsis Operational Plan: Kenai River Chinook Salmon Creel Survey and Inriver Netting Study, 2021-2023 by : Eric Wood
Download or read book Operational Plan: Kenai River Chinook Salmon Creel Survey and Inriver Netting Study, 2021-2023 written by Eric Wood and published by . This book was released on 2022 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Juvenile Abundance and Harvest of Unuk River Chinook Salmon, 2022-2024 by : Nathan Frost

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 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 Synopsis Amendment: Kenai River Chinook Salmon Sonar Assessment at River Mile 13.7, 2020-2022 by : Brandon H. Key
Download or read book Amendment: Kenai River Chinook Salmon Sonar Assessment at River Mile 13.7, 2020-2022 written by Brandon H. Key and published by . This book was released on 2022 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adaptive resolution imaging sonars (ARIS) are used to produce inriver abundance estimates of Kenai River early- and late-run Chinook salmon Onchorhynchus tshawytscha and Kasilof River late-run Chinook salmon. These sonars can be used to produce inseason estimates of fish 75 cm mid eye to tail fork length (METF) or longer, and when used over the entire run, can be used in conjunction with test fish data to produce postseason abundance estimates of all Chinook salmon regardless of size. Sonar estimates of Chinook salmon inriver passage provide the basis for estimating spawning escapement and implementing management plans that regulate harvest in the competing fisheries for these stocks.

Book Synopsis Local and Traditional Knowledge of Abundance of Chinook Salmon in the Kenai River by : Bronwyn Jones (Biologist)
Download or read book Local and Traditional Knowledge of Abundance of Chinook Salmon in the Kenai River written by Bronwyn Jones (Biologist) and published by . This book was released on 2017 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Alaska, statewide declines of Chinook salmon led to the development of the Chinook Salmon Research Initiative--a program aimed at better understanding these declines. Among the indicator stocks chosen for this study was the Kenai River in Southcentral Alaska. The Kenai River supports two distinct Chinook salmon runs, early and late. Together with its sockeye, coho, and pink salmon runs, the river provides opportunity for sport, personal use, educational, and commercial fisheries. This report focuses on Local Traditional Knowledge (LTK) of the Kenai River Chinook salmon stocks from long-term users of the Kenai River watershed as it pertains to patterns and trends of use in each stock.
