Abstract

Trout farming has a potential for becoming the primary source of high-quality fish products for the resident population of Krasnoyarsk Krai. Rainbow trout aquaculture is economically profitable if cheap balanced feed based on local ingredients is available. The article presents data on the composition of amino acids in imported and locally produced commercial fish feed, as well as alternative sources, such as flour, seed meal, by-products of biotechnological production, and aquatic organisms from the water bodies of Krasnoyarsk and the Yenisei River. We conclude that zooplankton and Gammarus lacustris G. O. Sars 1863 can provide rainbow trout with a diet balanced in amino acids, with the exception of methionine. The studied feed components from local plant biomass, by-products of biotechnological production, river macrozoobenthos and phytoplankton from local water bodies can be used as protein supplements for designing rainbow trout diets. Information presented in the article will be useful for fish farmers and practitioners involved in the development of new domestic fish feed
