This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chinook salmon Oncorhynchus tshawytscha smolt abundance and adult escapement will be estimated for the Taku stock of Chinook salmon originating from the Canadian portions of the Taku River drainage above the U.S./Canada border. This large glacial river flows into Taku Inlet about 30 km northeast of Juneau, Alaska. A modified Petersen estimator will be used to estimate smolt abundance for the 2017-2019 brood years, which represent smolt leaving the system during 2019-2021. Chinook salmon smolt will be captured April through June, systematically sampled to estimate mean length and weight and all healthy fish will be implanted with a coded wire tag and marked with an adipose fin clip. Escapement of large (≥660 mm; mid eye to fork of tail) and medium (401–659 mm; similarly, mid eye to fork of tail) Taku River adult Chinook salmon will be estimated using mark-recapture methodology in 2019-2021. Adult Chinook salmon will be captured and marked near Canyon Island in the lower Taku River using fish wheels and drift gillnets from late April through early August. Each fish will be tagged with uniquely numbered, solid-core spaghetti tags, and two secondary marks. In addition, fish will be sampled for use in age, sex, and length composition estimates of the spawning escapement.

Download or read book Spawning Abundance of Chinook Salmon in the Taku River in 2003 written by and published by . This book was released on 2006 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: A cooperative study involving the Department of Fisheries and Oceans Canada, the Alaska Department of Fish and Game, and the Taku River Tlingit First Nation was conducted to estimate the number of spawning Chinook salmon Oncorhynchus tshawytscha in the Taku River in 2003 with a mark-recapture experiment. Fish were captured at Canyon Island on the lower Taku River with fish wheels from May through August and were individually marked with back-sewn, solid-core spaghetti tags. All tagged fish were also batch marked with an opercle punch plus removal of the left axillary appendage. Sampling on the spawning grounds in tributaries was used to estimate the fraction of the population that had been marked. The estimated spawning abundance of small Chinook salmon ( 400 mm long; mid-eye to fork of tail) was 3,489 (SE = 1,052). Spawning abundance of medium-size Chinook salmon (401-659 mm) was estimated to be 16,780 (SE = 2,274). Finally, spawning abundance of large-size fish (= 660 mm) was estimated to be 36,435 (SE = 6,705), and the estimated total of all fish was 56,704 (SE = 7,158). The sum of the peak aerial survey counts of large spawning Chinook salmon conducted at five index tributaries of the Taku River was 16% of the mark-recapture estimate. Age 1.3 fish (1998 brood year) constituted an estimated 40% of the spawning population, followed by age 1.2 fish (1999 brood year), which constituted an estimated 29% of the population.

Download or read book Salmonid Field Protocols Handbook written by David H. Johnson and published by . This book was released on 2007 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first publication to collect, standardize, and recommend a scientifically rigorous set of field protocols for monitoring and assessing salmon and trout populations. Includes five additional techniques that can be used with any of the 13 principle methods to supplement information gathered.Over four dozen fisheries experts throughout the U.S. Pacific Northwest and beyond contributed their time to pick, write, and review the most reliable protocols for enumerating salmonids in the field. Presented in an easy to use format, each of the 18 peer-reviewed protocols covers objectives, sample design, data handling, personnel and operational requirements, and field and office techniques, including survey forms.Standardized monitoring protocols will improve data reliability, maximize opportunities for data sharing and data set comparability, and ultimately improve the ability to assess status and trends. The Handbook will also support consistency in data collection for salmonids at the international level.

This book was released on 2018 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: A cooperative study involving the Alaska Department of Fish and Game, Department of Fisheries and Oceans Canada, and the Taku River Tlingit First Nation was conducted to estimate the number of spawning Chinook salmon Oncorhynchus tshawytscha in the Taku River from 2008 to 2010 using mark–recapture methodology. Fish were captured annually near Canyon Island in the lower Taku River using fish wheels and set gillnets from late April through early August and were tagged using back-sewn, individually numbered, solid-core spaghetti tags. Two secondary marks, a left operculum punch and a left axillary finclip, were applied in case the primary spaghetti tag was lost between tagging and recapture. Sampling in the lower river assessment and Canadian commercial fisheries, and on the spawning grounds was used to estimate the fraction of the population that had been marked. Spawning abundance of large-sized Chinook salmon (≥660 mm mid-eye to fork of tail) was estimated at 26,645 (SE = 3,010) in 2008, 22,761 (SE = 2,871) in 2009, and 28,769 (SE = 2,546) in 2010. Spawning abundance of medium-sized Chinook salmon (401–659 mm mid -eye to fork of tail) was estimated at 12,889 (SE = 2,559) in 2008, 10,231 (SE = 1,788) in 2009, and 7,310 (SE = 935) in 2010.
