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.
由于n-3脂肪酸（二十碳五烯酸，EPA和二十二碳六烯酸，DHA）具有抗血栓和抗炎特性，且在海鱼中含量丰富，因此采用毛细管气相色谱法分析了在南非发现的18种淡水鱼鱼肉的脂肪酸组成。总体而言，与一些海鱼相比，所有研究的鱼类中EPA和DHA的含量较低，而花生四烯酸和亚油酸的含量较高。饱和脂肪占总脂肪酸的33%，单烯酸平均占35%。因此，所研究的鱼类作为n-3脂肪酸的来源不如海鱼。
