Abstract :In this study, seasonal variations of total fatty acid insert ignore into journalissuearticles values(FA);, phospholipid insert ignore into journalissuearticles values(PL); and triacylglycerol insert ignore into journalissuearticles values(TAG); compositions in liver tissues of catfish insert ignore into journalissuearticles values(Silurus triostegus); were investigated. Samples of S. trioste-gus were obtained from Atatürk Dam Lake, Turkey, in two month periods during one year as from May. The major components were palmitic acid insert ignore into journalissuearticles values(16:0);, stearic acid insert ignore into journalissuearticles values(18:0);, oleic acid insert ignore into journalissuearticles values(18:1n-9);, palmi-toleic acid insert ignore into journalissuearticles values(16:1n-7);, docosahexaenoic acid insert ignore into journalissuearticles values(DHA, 22:6n-3); and arachidonic acid insert ignore into journalissuearticles values(AA, 20:4n-6); in total lipid, 16:0, 18:0, 18:1n-9, eicosapentaenoic acid insert ignore into journalissuearticles values(EPA, 20:5n-3);, DHA and AA in PL, 16:0, 16:1n-7, 18:1n-9, linoleic acid insert ignore into journalissuearticles values(LA, 18:2n-6);, AA, EPA, DHA and docosapentaenoic acid insert ignore into journalissuearticles values(22:5n-3); in TAG extracted from the liver of S. triostegus in all seasons. N-3/n-6 ratio was found 2.00-2.61 in females, 1.15-2.75 in males in total lipid. The highest lipid content was found in May insert ignore into journalissuearticles values(2.39%); in the females. In the males, the highest level was found in September insert ignore into journalissuearticles values(2.91%);. In TAG fraction, the component with the lowest ratio in both sexes’ TAG is PUFA. In PL fraction, SFA, MUFA, and PUFA percentages were found at similar rates in both sexes in all months.
