Atlantic salmon is the species which is farmed the most in Norway, but other species such as halibut, cod, trout, crab and mussels and wrasse are also farmed. Each species has its own unique biological characteristics, and the feed must therefore be adapted to the different nutrient requirements of each species. For example, Atlantic cod and Atlantic halibut are much smaller than salmon at the start of their lives, and therefore need live feed instead of feed pellets.
To ensure good fish health and welfare, it is necessary to map the fish’s nutrient requirements in different phases of their lives. NIFES studies how different nutrients affect the development of larvae and fry in the different species.
