Essential amino acid (EAA) were 6921±11 and 7360.5±266.5 mg/100g in wild and cultured sea bass, respectively and the differences between them were insignificant (P>0.05). Saturated fatty acid (ƩSFA) were 26.50±0.06% and 25.11±0.01% in wild and cultured sea bass, respectively, and the differences between them was significant (P<0.05). Mono unsaturated fatty acids (ƩMUFA) were 27.55±0.22% and 30.14±0.02% andpoly unsaturated fatty acids (ƩPUFA) were 35.06±0.02% and 33.82±0.12% in wild and cultured sea bass respectively and the results between them were found insignificant (P>0.05).n3/n6rates were 2.02±0.01 and 1.02±0.06 inwild and cultured sea bass, respectively (P<0.05).It was found that C18:2n6c linoleic acid, C18:3n3a-linolenic acid and C22:1n9 erucic acid values in cultured sea bass and C20:5n3 EPA and C22:6n3 DHA in wild sea bass values were high.
