Abstract :In this study, the total protein and lipid contents and fatty acid composition of endemic freshwater fish Capoeta  antalyensis was investigated according to the variation in seasons and gender. Total protein content insert ignore into journalissuearticles values(%); of  C. antalyensis varied from 63.80% to 78.15% and total fat content from 4.57% to 21.29% in different seasons.  The palmitic, stearic, palmitoleic, oleic, eicosapentaenoic and docosahexaenoic acids were the most abundant  fatty acids in the muscles of C. antalyensis. The ratio of eicosapentaenoic acid insert ignore into journalissuearticles values(EPA); in muscles of both genders  was higher in spring and autumn, while docosahexaenoic acid insert ignore into journalissuearticles values(DHA); ratio was higher in winter. The ratio of  omega 3 polyunsaturated fatty acids insert ignore into journalissuearticles values(n3 PUFAs); content in the muscles reached the highest level in spring in  males and in summer in females. The ratios of n-3 PUFAs to omega 6 polyunsaturated fatty acids insert ignore into journalissuearticles values(n6 PUFAs);  in muscles of C. antalyensis of both genders changed from 3.29 to 5.44 as the seasons changed. Total fat and  fatty acid contents were found to be at the lowest level in both genders during winter. This shows that nutritional  content of C. antalyensis species is quite affected by variation in seasonal conditions.
