The annual averages of total lipid, total fatty acid and the ratios of fatty acids inmuscle and liver lipids of pikeperch from Lake Egirdir were determined. The qualityof muscle and liver lipids with respect to the ratio of n-3 fatty acids was evaluated.Total lipid contend was found 0.617r in male muscle. 0.56'7rin female muscle.5.7191- in male Iiver and 5.147(' in female Iiver. Total fatty acids composed of morethan half of total lipid in muscle and liver in both sexes. Palmitic acid (16:0) insaturated fatty acids (SF A), oleic acidt 18: 1) in monounsaturated fattyacids(M UF A),docosahexaenoic(22 :6n-3). eicosapentaenoic(10:5 n- 3) andarachidonic(20:4n-6) acids in polyunsaturated fatty acids(PUFA) were predominant.The n-3 fatty acids ratios were found 15.52'7(' in male muscle. 16.71 '7C'infemalemuscle, 12.02C'k in male liver and 11.26'7c in female liver. Although total lipidcontend is very low, pikeperch may be a source of n-3 fatty acids for the people whohave constantly consumption habits because the ratio ofn-3/n-6 is relatively high.
