NEMOVA1 1 Institute of Biology, Karelian Research Centre, RAS 185910, Petrozavodsk, Pushkinskaya str., 11 E-mail: vasil@krc.karelia.ru 2 Vologda State University 160035, Vologda, Leninа str., 15 Статья поступила 25.05.2015 Принята к печати 30.09.2015 ABSTRACT We studied the growth performance and liрid composition of liver, muscles and visceral fat in rainbow trout Parasalmo mykiss (Walbaum, 1792) and the diets used in its cultivation during the springsummer season. <...> The differences in dietary liрid composition determined modifications in the biochemical composition of tissues of rainbow trout and had an effect on the weight and growth rate of the fish. <...> Among the environmental factors, dietary composition and the degree of food availability forms exogenous heterogeneity of fish. <...> Trophic chains are formed during the long process of coevolution, therefore biochemical composition of native feed objects is generally considered to be the most appropriate for nor208 mal growth and development of fish. <...> The presence of non-typical ingredients for the nаtural diet can have a significant effect on fish metabolism and, consequently, result in a change of functioning at all levels of organism organization (from the adaptive response to disease states). Vasilyeva O. B., Nazarova M. А., Riрatti P. О., Nemova N. N., 2016 The effects of various feed ingredients on the fish tissue composition and the growth performance are now actively investigated, and one of the most problematic issues is the liрid and fatty acids composition of the feeds [Bell et al., 2010; Pratoomyot et al., 2011; Yigit et al., 2012, etc.]. <...> Impact of these factors on the lipid composition in visceral fat, muscle and liver of rainbow trout Parasalmo mykiss (Walbaum, 1792) was studied in this paper. <...> Total liрids (TL), total phospholipids (PL), triacylglycerols (TAG), cholesterol (Ch), cholesterol esters (ChE); individual PL phosphatidylinositol (PI), phosphatidylserine <...>
