Dietary micronutrient composition affects fillet texture and muscle cell size in Atlantic salmon (Salmo salar)
During the past 20 years, plant ingredients have taken over as the main constituents in feed for Atlantic salmon. This has changed the nutrient composition of the feeds, the bioavailability of nutrients and perhaps nutrient metabolism. Plant‐based diets also contain more anti‐nutrients. The EU‐funde...
