Book Synopsis Principles of Salmonid Culture by : W. Pennell
Download or read book Principles of Salmonid Culture written by W. Pennell and published by Elsevier. This book was released on 1996-10-11 with total page 1071 pages. Available in PDF, EPUB and Kindle. Book excerpt: As salmonids have been reared for more than a century in many countries, one might expect that principles are well established and provide a solid foundation for salmonid aquaculture. Indeed, some of the methods used today in salmonid rearing are nearly identical to those employed one hundred years ago. Areas of salmonid research today include nutrition, smolt and stress physiology, genetics and biotechnology. The purpose of this book is to provide a useful synthesis of the biology and culture of salmonid fishes. The important practices in salmonid culture as well as the theory behind them is described. This volume will be of interest to students, researchers, fisheries biologists and managers as well as practising aquaculturists.
Book Synopsis Effects of Temperature Ration and Size on Growth of Juvenile Steelhead Trout, Salmo Gairdneri by : Wayne A. Wurtsbaugh
Download or read book Effects of Temperature Ration and Size on Growth of Juvenile Steelhead Trout, Salmo Gairdneri written by Wayne A. Wurtsbaugh and published by . This book was released on 1973 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of temperature, temperature fluctuation, and fish size on the growth of juvenile steelhead trout (Salmo gairdneri) were studied in experiments which lasted 10 to 25 days. Groups of fish were fed at ration levels varying from near-starvation to repletion. Decelerating, curvilinear relationships between rates of food consumption and growth were defined in most of the experiments. At ration levels near maintenance, temperatures elevated 3 and 6 C above the seasonal ambient temperatures decreased the growth of the trout. As feeding rate increased, the detrimental effect of temperature on growth was ameliorated. At repletion feeding levels, elevation of temperature up to approximately 17 C increased trout growth rates by increasing the maximum food consumption rates of the fish. With temperature increase from 6.9 to 22.5 C the maintenance rations of the trout increased from 2.2 to 7.4% body weight/day. Large diel temperature fluctuations of 4 and 8 C did not increase growth rates and in some cases decreased growth rates to levels below those of fish kept at constant temperatures. Increase of fish size from 0.58 to 3.36 g decreased the maintenance rations (per gram of tissue) of the trout. This decrease was attributed to decreases in metabolic rate that are associated with increases in fish size. As a consequence of this size-dependent change in metabolic rate, large fish grew faster than small fish at low ration levels. However, at ration levels greater than 9%/day, small fish grew faster than large fish. At the highest ration levels fed (9- 12%/day) gross food conversion efficiency of the large fish began to decline, while efficiencies of small fish continued to increase with increases in ration size. Periodic sampling of steelhead trout in a small coastal stream indicated that growth rates of these wild trout ranged from -0.18 to 1.6%/day. Food consumption rates of the wild trout were estimated to range from 2.0 to 7.6%/day; considerably less than the maximum consumption rates of trout kept in the laboratory. At these food consumption rates it is estimated that increases of stream temperature above the normal seasonal temperatures would decrease the growth rates of wild steelhead trout.

Book Synopsis Sockeye Salmon (Oncorhynchus Nerka) by : Canada. Department of Fisheries and Oceans
Download or read book Sockeye Salmon (Oncorhynchus Nerka) written by Canada. Department of Fisheries and Oceans and published by Fisheries and Oceans, Information and Publications Branch. 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.
