Fatty acid composition and omega 3/omega 6 ratios of the muscle lipids of six fish species in Sugla Lake, Turkey

Fatty acid composition of the muscle lipids of Carassius gibelio, Pseudophoxinus anatolicus, Sander lucioperca, Tinca tinca, Vimba vimba tenella and Capoeta capoeta in Sugla Lake were determined. In all species, palmitic acid (13.25-18.54% of total fatty acids) and oleic acid (11.93-34.23% of total fatty acids) were identified as major saturated fatty acid (SFA) and monounsaturated fatty acid (MUFA), respectively. Docosahexaenoic acid (DHA) was found to be the major polyunsaturated fatty acid (PUFA) in T tinca, C. capoeta, C. gibelio, P anatolicus and S. lucioperca while the predominant PUFA of V vimba tenella was eicosapentaenoic acid (EPA). S. lucioperca contained more omega 3 fatty acids than the other fish species. The percentages of total omega 3 fatty acids were higher than those of total omega 6 fatty acids in all species. Since R anatolicus is endemic and endangered, this species should be protected and produced for future marketing.
