Abstract

The composition of fatty acids of the muscles, liver and carcass of wild and cultured Mesopotamichthys sharpeyi were determined by gas-liquid chromatography. In all the samples studied, the principle saturated fatty acids (SFA) and Monounsaturated fatty acids (MUFA) were palmitic (C16:0) and oleic (C18:1n-9) acids respectively. The results showed that cultured fish muscle and liver contained a higher level of polyunsaturated fatty acids (PUFA), particularly docosahexaenoic acids (DHA), eicosapentaenoic acids (EPA) and arachidonic acid (ARA) (p<0.05), whereas wild fish muscles contained a higher level of SFA. The results indicate that the fatty acids composition of Benni tissues were different by environment types and feeding qualities. Finally, the cultured Mesopotamichthys sharpeyi can be a healthy component in the human diet according to dietary fatty acids profiles requirement.
