Fatty acid composition of wild and farmed Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss)

Fatty acid composition of wild and farmed Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss)

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...

Zusammenfassung: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.
