Fatty acid composition of some South African fresh-water fish.
Because of the antithrombotic and anti-inflammatory properties of the n-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are found in large quantities in marine fish, the fatty acid composition of the flesh of 18 different species of fresh-water fish found in South Africa was analysed by capillary gas chromatography. In general all the fish studied had low percentages of EPA and DHA and fairly high percentages of arachidonic acid and linoleic acid when compared with some marine fish. The saturated fats constituted 33% of total fatty acids and the mono-enes averaged 35%. The fish studied are therefore not as good a source of n-3 fatty acids as marine fish.
