The work is focused on the nutrition and farming technology influences on the changes of the quality of common carp (Cyprinus carpio L.) and european catfish (Silurus glanis L.) meat. For the first experiment were used 6 groups of fish (common carp). Five of those were fed on cereals (maize, wheat, triticale, rye and barley), the sixth group was left on natural food by way of the control group. For the second experiment were used two groups of fish (european catfish). The first group was bred by the classical technology in fresh water ponds using natural food (dietary fish) by way of the control group. The second group was bred intensively in warm water in controlled conditions using feed compouned. In both of groups were defined following characteristics: weight yield, sensoric analysis, content of nitrogen compounds, fat content and spectrum of fatty acids in fat. It was ascertained that the rearing technology affects the results in all monitored characteristics. The biggest attention was payed to the results of fatty acids spectrum. While in the test using common carp was proved a higher proportion of PUFA (inclusive EPA and DHA) in the control group, in the test using catfish was this proportion higher in intensively reared group.
