Fish are the major dietary source of very-long-chain n-3 polyunsaturated fatty acids. We investigated whether cultured fish contain fewer n-3 fatty acids than do wild fish. Fifty-eight trout, 51 eel, and 5 salmon were collected from fishermen and hatcheries throughout Europe, pooled into 23 lots (8 of wild and 15 of cultured fish), and analyzed. The ratio of n-3 to n-6 polyunsaturates was significantly lower in cultured than in wild fish (2 vs 7 in trout, 2 vs 5 in eel, and 6 vs 11 in salmon). Hunted fish are a better source of n-3 polyunsaturates than are cultured fish.
鱼类是超长链n-3多不饱和脂肪酸的主要饮食来源。我们调查了养殖鱼类所含的n-3脂肪酸是否比野生鱼类少。从欧洲各地的渔民和孵化场收集了58条鳟鱼、51条鳗鱼和5条鲑鱼，合并为23组（8组野生鱼和15组养殖鱼）并进行分析。养殖鱼中n-3与n-6多不饱和脂肪酸的比例显著低于野生鱼（鳟鱼中为2比7，鳗鱼中为2比5，鲑鱼中为6比11）。捕猎的鱼比养殖鱼是更好的n-3多不饱和脂肪酸来源。
