dc.description.abstract Juvenile hybrids (9.43±0.09 g) of pikeperch (Sander lucioperca ?) and Volga pikeperch (S. volgensis ?) were reared in a recirculation system for 54 days. Fish were fed one of four experimental diets in which the principal source of lipid was fish oil, rapeseed oil, sunflower oil, or soy oil (5%), added to a basal diet (fat content 5.9%) and fed at a ratio of 2% of the body weight. The specific growth rate was moderate (0.47-0.66%/day) and did not differ between groups. Body composition traits (dry matter, crude protein, crude ash, crude fat, fillet fat content) were not affected by the different diets. However, the accumulation of oleic acid (C18:1 n-9) was significantly highest in the rapeseed group, and sunflower oil resulted in the highest proportion of linoleic acid (C18:2 n-6). Among the n-3 polyunsaturated fatty acids, the a-linolenic acid (C18:3 n-3) content in the fillet of fish fed the diet containing rapeseed oil was significantly higher than in the fillet of animals fed the diets with fish or sunflower oil and the eicosapentaenoic acid (C20:5 n-3) content in the sunflower group was significantly lower than in the fish or rapeseed groups. Thus, some of the fatty acid muscle contents were influenced by their concentration in the feed. en_US
