Abstract :Fatty acid compositions of total lipids in the muscle of 9 freshwater fish species were examined via gas chromatography. Palmitic acid and oleic acid were the predominant saturated insert ignore into journalissuearticles values(SFA); and monounsaturated fatty acids insert ignore into journalissuearticles values(MUFA); in all the species analyzed. The highest value of total SFA was detected in Liza abu insert ignore into journalissuearticles values(48.94%);. Alburnus mossulensis had the greatest percentage of total MUFA insert ignore into journalissuearticles values(55.56%);. Eicosapentaenoic acid insert ignore into journalissuearticles values(EPA); and docosahexaenoic acid insert ignore into journalissuearticles values(DHA); were the most abundant PUFA in all the species analyzed. Cyprinion macrostomus had the highest percentage insert ignore into journalissuearticles values(72.65%); of total PUFA. The ratio of w3/w6 PUFAs ranged from 0.39 to 3.53. Chondrostoma regium, Barbus rajonorum, Carasobarbus luteus, Leuciscus lepidus, Acanthobrama marmid, C. macrostomus, and Silurus triostegus may be preferable for a healthy diet as a result of their high C20:5w3 and C22:6w3 content. A. mossulensis and L. abu had an w3/w6 PUFAs ratio of less than 1. They are not as good a source of w3 fatty acids as freshwater fish.
