This study was performed to determine proximate composition and fatty acids in muscle of common carp and grass carp that are commonly consumed in Iran. There is no significant difference in the content of protein, lipid and ash samples of in these two fish species (p>0.05). Grass carp had significantly higher moisture contents than common carp. The fatty acid composition of common carp and grass carp were found to be 32.86 and 34.06% saturated (SFA), 39.43 and 25.02% monounsaturated (MUFAs) and 24.13 and 37.54% polyunsaturated fatty acids (PUFAs), respectively. In both fish, palmitic acid C16:0 and oleic C18:1 n-9 acid were the principal saturated and monounsaturated fatty acids, respectively. The dominant poly unsaturated fatty acid (PUFA) was Docosahexaenoic acid (C22: 6n-3) in grass carp and Linoleic acid (C18: 2n-6) in common carp. The content of n3 PUFAs was 8.6% for common carp and 25/3% for grass carp. Arachidonic acid (20:4n6) content was 2.55% in grass carp and 1.33% in common carp. Muscle fatty acid composition of common and grass carp showed that there are significant difference in among all the fatty acids except for 22:0 and SFA(p<0.05).
