Modulation of selenium tissue distribution and selenoproteins expression in Atlantic salmon (Salmo salar L.) fed diets with graded levels of plant ingredients
Increased substitution of marine ingredients by terrestrial plant products in aquafeeds has proved to be suitable for Atlantic salmon farming. However, a reduction in omega-3 long-chain polyunsaturated fatty acids is a consequence of this substitution. In contrast, relatively little attention has be...

Increased substitution of marine ingredients by terrestrial plant products in aquafeeds has proved to be suitable for Atlantic salmon farming.
