This book was released on 1987 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: A three-day symposium was organized by the Department of Fisheries and Oceans and convened at Nanaimo, British Columbia in November 1985. Advice on subject matter and participation came from an external committee of senior scientists and administrators in contributing agencies in Canada, Japan, the United States, and the Union of Soviet Socialist Republics. The papers included in the proceedings deal with sockeye biology and stock management. Papers on sockeye biology are divided into those concerned primarily with life history strategies and enhancement and development. Papers dealing with management are divided into the tools of management and management of some principal stocks.

This book was released on 2004 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annual mark-recapture studies of adult Taku River sockeye salmon (Oncorhyncus nerka) stocks were conducted by the Alaska Department of Fish and Game, the Canadian Department of Fisheries and Oceans and the Taku River First Nation from 1998 to 2002. The objectives of the program were: to provide annual inseason estimates of the inriver abundance of sockeye salmon and to document biological characteristics (migratory timing, migratory rates and age, sex, and size composition) of Taku River sockeye stocks. Marked-to unmarked ratios of salmon harvested in the Canadian inriver gillnet fisheries were used to develop estimates of the inriver abundance of sockeye. During the years 1998 to 2002, an annual averageof 5,349 sockeye salmon were tagged in fish wheels located at Canyon Island, Alaska, of which an average of 1,080 (20.2%) sockeye were subsequently recovered in fisheries or on the spawning grounds.The annual post-season inriver runestimates of sockeye salmon past Canyon Island from 1998 to 2002 was estimated to be 91,548, 113,705, 115,693, 192,269, and 135,233, fish respectively. Annual inriver Canadian commercial, aboriginal and test fisheries combined harvested 19,038, 20,681, 27,942, 47,998, and 31,053 sockeye salmon during those same years (1998 to 2002). The resulting annual spawning escapement estimtes for Taku River sockeye salmon from 1998 to 2002 was 72,271, 95,562, 87,298, 144,071, 103,343, fish respectively.The migratory timing (mean dates and standard deviation of migration) and run timing of the sockeye salmon run was similar to the 15 year average. The Kuthai Lake sockeye salmon stocks dominated the early portion, the Little Trapper Lake the middle portion, and the Tatsamenie Lake and mainstem stocks the late portion of the Taku River sockeye salmon run. Pink fish wheel catches were strong in 1998 and 1999 but below average in 2000 to 2002. Chum salmon fish wheel catches for this 5-year period continued to exhibit the trend of low catches that began in the mid-1980's.

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 178 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
