- •
The best digestible protein:energy ratio was determined in net cages.
- •
The highest profitability for whole fish production was achieved with 28% DP/13.4 MJ DE kg− 1.
- •
The highest fillet yield was obtained with 30% DP.
- •
Choline was not effective in protecting the liver against hepatic steatosis.
- •
Diets with no choline and oil supplementation determined a lower resistance to stress.
