Abstract

In the present study, the effects of season on fatty acid composition, total lipids, and omega 3/omega 6 ratios of northern pike muscle lipids in Kizilirmak River (Kirikkale, Turkey) were investigated. A total of 35 different fatty acids were determined in gas chromatography. Among these, palmitic, oleic, and palmitoleic acids had the highest proportion. The main polyunsaturated fatty acids (PUFAs) were found to be docosahexaenoic acid, eicosapentaenoic acid, and arachidonic acid. There were more PUFAs than monounsaturated fatty acids (MUFA) in all seasons. Similarly, the percentages of omega 3 fatty acids were higher than those of total omega 6 fatty acids in the fatty acid composition omega 3/omega 6 ratios were calculated as 1.53, 1.32, 1.97, and 1.71 in spring, summer, autumn and winter, respectively. Overall, we found that the fatty acid composition and omega 3/omega 6 fatty acid ratio in the muscle of northern pike were significantly influenced by season.
