Fish oils are the main source of omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) , keep the blood cholesterol level low and thus help in controlling the cardiovascular diseases. In the present study, the liver and muscle tissues of Sander lucioperca from Rasht region in the south of the Caspian Sea, Iran in June 2013 were separately extracted for their lipid content and fatty acids composition using the method of Blight and Dyer. The compounds were determined by Gas Chromatography-Mass Spectrometry (GC- MS). The components detected in the liver and muscle tissues, including saturated fatty acids Palmitic acid and Stearic acid, monounsaturated fatty acid Oleic acid, polyunsaturated fatty acids (PUFA) Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA) and two methyl esters of fatty acids including Octadecanoic acid, methyl ester and Hexadecanoic acid, methyl ester. The results showed that the dominant fatty acids in liver and muscle tissues were Docosahexaenoic acid (DHA) and Palmitic acid.
