Abstract

The objective of this study was to make a comparative analysis of the fatty acid composition of the rainbow trout (Oncorhynchus mykiss Walbaum, 1792) with consumption size of 250-300 g, from two different aquaculture facilities - coldwater fishponds (fishpond A and fishpond B) in Macedonia, at different ambient conditions in the aquatic environment, and with the use of pelleted food from different manufacturers. Considering the results of the fatty acid composition of the rainbow trout from the fishpond A and the fishpond B, it can be concluded that the content of the saturated fatty acids (SFA) is higher in the fishpond B (20.303%) compared to the fishpond A (16.155%), while the content of the monounsaturated fatty acids (MUFA) and the polyunsaturated fatty acids (PUFA) is greater in the fishpond A (MUFA - 53.364%; PUFA - 30.435%) compared to the fishpond B (MUFA - 52.359%; PUFA - 27.268%). Overall, by a comparative analysis of the qualitative properties of the rainbow trout from the both aquaculture facilities, the ambient conditions prevailing in the aquatic environment, and the used forage mixtures for feeding fish, it can be concluded that the both aquaculture facilities are producing fish with high nutritional quality in terms of the fatty acid composition.
