Abstract
Common carp (Cyprinus carpio L.) fingerlings were fed five diets in triplicate containing 0, 2, 3, 4 and 5% of linseed oil for 75 days to determine the effect of the different concentration of linseed oil on growth parameters, as well as on the proximate and fatty acid composition of the fish flesh. The fish had the average initial weight of 200 g and were stocked in 15 cages. The fish which were fed with the diets supplemented with 3, 4 and 5% linseed oil had significantly better growth parameters compared to the fish fed with the diets supplemented with 0 or 2% linseed oil. The lipid content in muscle increased from 1.25% in the control group without the addition of linseed oil, to 1.46%; 1.56%; 1.94% and 2.37% in the groups of fish fed with the diets supplemented with 2, 3, 4 and 5% linseed oil, respectively. The fatty acid profiles in the muscle tissue reflected the diet concentrations with significant increases (p
