Effect of dietary fat level on weight gain, digestibility, and fillet composition of Atlantic halibut

摘要: Abstract Two experiments were carried out to obtain information on the effect of dietary fat levels juvenile (6–12 g) and larger (0.6–1.5 kg) Atlantic halibut ( Hippoglossus hippoglossus ). The fed dry diets containing 12% 54% protein 21% 49% protein, respectively. fish moist formulated be isonitrogenous (19–21% a wet-weight basis), contain equal amounts carbohydrate (9–10%) increasing (8, 12, 16 or 20%, respectively). Dietary level did not result in significant differences weight gain for any two size classes halibut. No effects various seen feed efficiency, chemical composition fillets livers digestibility matter, fish. Large individual variation was observed all recorded data.
