Book Description
"A study of the Pacific salmon, sockeye (Oncorhynchus nerka, (Walbaum), pink (0. gorbuscha. (Walbaum), spring (0. tshawytscha, (Walbaum)), coho (0. kisutch. (Walbaum)), chum (0. keta, (Walbaum)), and the steelhead trout (Salmo galrdnerlii, Richardson), was carried out during the summers of 1946 and 1947 in conjunction with the general programme of the Skeena River Salmon Investigation which has been conducted by the Fisheries Research Board of Canada since 1944. During the winter of 1946-47, while at McGill University, Montreal, Que., the morphometric data and systematic counts collected during the first summer were analysed and a male and female of each species were dissected. In the following winter at the Pacific Biological Station, Nanaimo, B. C , the analyses were completed by determining the growth from the scales and by incorporating such data collected during the second summer as was necessary for a sound interpretation of the results already obtained.[...]" --

Book Description
Every year, countless juvenile Pacific salmon leave streams and rivers on their migration to feeding grounds in the North Pacific Ocean and the Bering Sea. After periods ranging from a few months to several years, adult salmon enter rivers along the coasts of Asia and North America to spawn and complete their life cycle. Within this general outline, various life history patterns, both among and within species, involve diverse ways of exploiting freshwater, estuarine, and marine habitats. There are seven species of Pacific salmon. Five (coho, chinook chum, pink, and sockeye) occur in both North America and Asia. Their complex life histories and spectacular migrations have long fascinated biologists and amateurs alike. Physiological Ecology of Pacific Salmon provides comprehensive reviews by leading researchers of the physiological adaptations that allow Pacific Salmon to sustain themselves in the diverse environments in which they live. It begins with an analysis of energy expenditure and continues with reviews of locomotion, growth, feeding, and nutrition. Subsequent chapters deal with osmotic adjustments enabling the passage between fresh and salt water, nitrogen excretion and regulation of acid-base balance, circulation and gas transfer, and finally, responses to stress. This thorough and authoritative volume will be a valuable reference for students and researchers of biology and fisheries science as they seek to understand the environmental requirements for the perpetuation of these unique and valuable species.
