The goal of this study was to examine the FA composition of wild and farmed Atlantic salmon (AS) and rainbow trout (RT). FA profiles were obtained by GC/FID. Results showed that lipid and n-3 highly unsaturated FA contents of farmed and wild AS were similar. Total n-3 and n-6 PUFA were significantly higher in farmed AS than in wild AS. Farmed RT contained more fat and less n-3 PUFA than wild RT. Our results show that farmed salmonids provide high levels of n-3 HUFA to consumers.
本研究的目的是检测野生和养殖大西洋鲑（AS）及虹鳟（RT）的脂肪酸（FA）组成。通过气相色谱/火焰离子化检测器（GC/FID）获得脂肪酸谱。结果显示，养殖和野生大西洋鲑的脂质及n-3高度不饱和脂肪酸含量相似。养殖大西洋鲑的总n-3和n-6多不饱和脂肪酸（PUFA）显著高于野生大西洋鲑。养殖虹鳟比野生虹鳟含有更多脂肪和更少的n-3多不饱和脂肪酸。我们的结果表明，养殖鲑科鱼类为消费者提供了高水平的n-3高度不饱和脂肪酸。
