Growth performance, fast muscle development and chemical composition of juvenile lumpfish (Cyclopterus lumpus) fed diets incorporating soy and pea protein concentrates
Lumpfish (Cyclopterus lumpus) are widely applied as biological delousers in open net-pen farming of Atlantic salmon. As a species new to farming it is necessary to obtain a comprehensive understanding of the capacity of lumpfish to utilize plant derived feed ingredients. A feeding trial lasting for...
