Comparative indicators of the chemical composition of farmed and wild common carp (Cyprinus carpio, L. 1758)

In this study, a comparative analysis of certain qualitative parameters of common carp (Cyprinus carpio L. 1758) was performed, i.e. common carp from aquaculture (warm-water fishpond) and open waters (Prespa Lake), during the autumn. The qualitative properties of the common carp were established by the determination of the chemical composition of the fish meat, the energy value of meat, and the microbiological analysis for the total number of microorganisms on fish skin and the presence of Salmonella sp. and Listeria monocytogenes. In addition to the main research, analyses of the physico - chemical properties and a microbiological quality of the water in which the common carp resides were included. The results obtained during the examination of the chemical composition of the common carp meat from the warm-water fishpond shown the mean value of 73.580% water, 14.433% protein, 6.850% fat, and 1.036% ash, while in common carp from Prespa Lake: 73.223% water, 15.333% protein, 3.483% fat and 1.053% ash. The differences in the values of fat content between fish meat from a warm-water fish pond and Prespa Lake are statistically significant on level р
