The literature on marking fish with chemicals is reviewed, with critical commentary and suggestions for desirable areas of research. A variety of substances have been used to mark aquatic animals by methods such as deep injection, subcutaneous injection, tattooing, immersuion, daubing, and feeding. Over 100 dyes and other chemicals that have been used for marking aquatic animals are listed and the results of published or unpublished experiments using each one are summarized. A bibliography of over 150 titles is given.

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.

The 1970 fall chinook salmon feeding trials indicated that dry pelleted diets were equal to moist pelleted diets with similar formulations. A superior diet was produced by reducing the ratio of dried whey product and wheat germ meal to 1:1 and eliminating cottonseed meal. This formulation feed at a 45-percent protein level was more efficient than other protein levels fed. Growth was not reduced when the soybean oil supplement was lowered from 6 to 2 percent of the diet. Two corn distillers' products that were substituted as partial replacements for dried whey product did not enhance fish growth. Storage of the Abernathy dry pellet at room temperature did not alter the nutritional adequacy of the diet.
