Bugaev V.F. Asian Sockeye Salmon (freshwater period of life, biological structure, population dynamics)

Petropavlovsk-Kamchatsky: Kamchatpress, 2011. — 292 p. — ISBN: 978-5-9610-0159-4.In Asia, the sockeye is the most abundant on the Kamchatka Peninsula in some years where ap­proximately 90–95 % of all the Asian sockeye is harvested in the watersheds of the Kamchatka and Ozernaya rivers alone. This study is a summary of long-term observations on the Asian sockeye, and is based on the results of the author's 20 years of research. He examines the biological characteristics of 38 local sockeye populations (from Iturup Is. to Eastern Chukotka). Long-term data was used to analyze the interannual variability in the growth of juvenile sockeye of the Kamchatka and Ozernaya rivers. Questions concerning the structural analysis of the scales in juveniles and spawners of the sockeye are discussed in detail for the purpose of standardizing the age-determination procedure. Data on the feeding behaviour of juvenile sockeye in the watersheds of the Kamchatka and Ozernaya rivers are presented, and questions concerning the food competition of fish in the Kamchatka River watershed are discussed. The causes of fluctuations in the abundance of the sockeye in the Kamchatka and Ozernaya rivers are analyzed, and the latest methods of forecasting the abundance of these stocks and the fluctuations in the abundance of some secondary populations of Asian sockeye are examined. The author also looks at the future of natural and artificial reproduction of the species. The book also includes reference information.
