Abstract

In this study, seasonal and sexual variations of fatty acid profiles of Pseudophoxinus fahrettini and Capoeta mauricii which are freshwater fishes in Turkey inland waters were investigated. The monounsaturated fatty acids (MUFAs) values were higher than saturated fatty acids (SFAs) and polyunsaturated fatty acids (PUFAs) values for both species. Also the ratios of MUFAs in P. fahrettini were higher than those of C. mauricii in all seasons. The results indicated that palmitic acid was the most dominant SFA for both species in all seasons. Oleic acid in the muscle of P. fahrettini and palmitoleic acid in the muscle of C. mauricii were the highest MUFA respectively in both genders in all seasons. The highest ratios of omega 3 PUFAs were 23.00% in the muscle of C. mauricii in summer and 18.44% in P. fahrettini in winter. The ratios of omega 3 PUFAs in muscles of both species and genders were higher than the ratios of omega 6 PUFAs during all the seasons. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) were significantly higher than the other PUFAs in both sexes of the species. The ratio of omega 3 PUFAs to omega 6 PUFAs was higher than 1.76 in both species and genders in all seasons.
