Evaluation of nutritional quality of the common carp (Cyprinus carpio) enriched in fatty acids

Abstract

The knowledge of the feed requirements of fish species allows developing well-balanced feed formulations for successful intensive culture. The target of this study was to investigate the effect of supplementing the fish fodder with different types of oils, on fish growing and meat quality. The experiments were conducted on common carp using olive, soy and fish oil preparations. The results of these experiments showed that increasing the content of fats in fish diet allowed a faster growth of common carp and better weight increasing results. The fatty acids and aminoacids profiles ofthe fish meat highly depended on the type of oil used in the feedingexperiment. According to our results, out of the tested variants the fish oil based fodder is most favorable for fish feeding, allowing the accumulation of large quantities of highly unsaturated fatty acids in meat.
