DOI : 10.4194/1303-2712-v15_1_11 In this study, the total lipid, total protein and fatty acid compositions of Capoetaangorae were investigated. Total lipid content ratios (as wet weight) were found to be as 1.44% in spring, 6.41% in summer, 4.25% in autumn and 4.29% in winter. Total protein ratios in the muscle of C. angorae also varied from16.55% to19.24% during the year. The major fatty acids in the muscles of both sexes were palmitic, oleic, palmitoleic, eicosapentaenoic and docosahexaenoicacids. The proportions of n3 PUFAs were higher than those of n6 PUFAs through the year. The ratios of total n6 PUFAs to n3 PUFAs in the muscle of C. angorae changed from 0.14 to 0.19 in female and from 0.12 to 0.31 in males, respectively. The levels of EPA+DHA in the muscles of both genders changed from 0.19 to 0.91g/100g wet weight. The results showed that the ratios of total lipid and fatty acids in the muscle of C. angorae significantly varied by the year. Keywords : Capoeta angorae, fatty acids, season, nutritional value
