In the present study, seasonal changes in the fatty acid composition of the chironomidae larvae were determined by gas chromatography. When the seasonal variation of fatty acids were compared, a significant increase were observed caproic acid (6:0), palmitic acid (16:0), palmitoleic acid (16:1 n7), stearic acid (18:0), oleic acid (18:1 n9), linoleic acid (18:2 n6) and arachidonic acid (20:4 n6) in all seasons. A significant increase were observed in myristic acid (14:0) in spring and winter; margaroleic acid (17:1) in autumn; eicosapentaenoic acid in spring and linolenic acid (18:3 n3) in spring, summer and winter. When the fatty acids were compared, caproic acid (6:0), palmitic acid (16:0), stearic acid (18:0) and linoleic acid (18:2 n6) level were found to be significantly high. When fatty acids were compared statistically, differences were detected between seasons (p < 0,001). In conclusion, it is suggested that the reason for these differences is due to the variety of food in different seasons and larval development feature.
