An extended feeding history with a stearidonic acid enriched diet from parr to smolt increases n-3 long-chain polyunsaturated fatty acids biosynthesis in white muscle and liver of Atlantic salmon (Salmo salar L.)

► n-3 LC-PUFA biosynthesis in Atlantic salmon tissues was investigated. ► Nutritional and environmental factors influenced n-3 LC-PUFA biosynthesis. ► Stearidonic acid enriched diet promoted n-3 LC-PUFA biosynthesis.
