The sixth edition of the standard guide for trout farmers covers the latest developments and new opportunities, not only for rainbow trout farming in the sea but also for hatching and growing brown trout for angling. The design and construction of trout farms is clearly outlined and every stage of trout production is dealt with in detail: hatching and fry production, fish feeds and feeding, hygiene and the prevention and treament of disease, and the management of brood stock. Processing and marketing are discussed together with ways and means of increasing profability. Special attention is given to the prevention of pollution and protection of the environment and to recent developments such as cage farms in deep lakes, disease control and vaccination against disease, and co–operative farming.
