ANALYTICAL REVIEW OF APPROACHES TO THE USE OF ALTERNATIVE FEEDS IN AQUACULTURE WHEN IMPROVING ENVIRONMENTAL SCHEMES

Abstract

Information from foreign literary sources on the possibility of growing Atlantic salmon (Salmo salar) with the inclusion of dried and / or defatted biomass of the larvae of the Black Soldier fly (Hermetia illucens) in the diet is summarized. Brief data on the physiology and life cycle of the named insect, as well as the content of proteins and fatty acids are given. It has been shown that flour from dried biomass of insect larvae contains a large amount of amino acids and fatty acids. Information on the effect of meal from insect larvae on an increase in the mass of juveniles and adults of Atlantic salmon fish, digestibility of dry matter of feed, organoleptic characteristics of fish fillets, amino acid and fatty acid composition and other indicators when replacing fish meal and soybean meal with meal from larvae is briefly presented Hermetia illucens. It was concluded that the inclusion of flour from insect biomass in certain proportions has a positive effect on the growth and vital activity of fish of the Salmo salar species, however, there are limits for inclusion in the diet. The literature also summarizes the literature on the possibility of using krill biomass in the diet for growing salmon, briefly provides information on its volume of formation and composition.
