Book Description
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 Description
Two rainbow trout (Salmo gairdneri) reference diets (a practical reference (control) diet (C201) formulated for feed development studies and semipurified reference (basal) diet (C101) for nutrient requirement studies) were used in a 16-wk feeding trial to investigate their suitability for Arctic charr (Salvelinus alpinus). Biochemical and performance parameters together with gross morphological and histological evidence showed that diet C201 was a suitable reference diet for feed development studies in Arctic charr. It produced no pathological conditions. However diet C101 was not suitable for nutrient requirement studies in Arctic charr; compared to diet C201 it produced high mortalities, lower weight gains (growth) and low hematocrit values. It resulted in liver which was beige-gray in color, had an abnormal glycogen distribution and accumulation and had a higher weight to body weight ratio. This abnormal liver had a higher content of lipid (dry weight), moisture, calcium, iron and cobalt and a lower content of fat-free solids, copper, magnesium, and zinc. Diet C101 also produced higher whole body contents of manganese, and cobalt and lower content of selenium.
