Energy dilution with α-cellulose in diets for Atlantic cod (Gadus morhua L.) juveniles — Effects on growth, feed intake, liver size and digestibility of nutrients

Farmed Atlantic cod (Gadus morhua L.) is known to grow large liver, while muscle growth is preferred. Therefore, the main focus of this feeding trial was to find a strategy to achieve reduced liver size without compromising total growth, feed utilization, digestibility of nutrients or fish health. All experimental diets held a similar protein to energy (P:E) ratio, but indigestible fibre was added to dilute total energy. Two basal diet mixtures...
