Reduced growth of Atlantic cod in non‐lethal hypoxic conditions
Growth in length and mass, improvements in condition, as well as final condition of c. 700 g Atlantic cod Gadus morhua were significantly less at 45% and 56% O 2 saturation than at 65%, 75%, 84% and 93% O 2 saturation. Hypoxia decreased food consumption. In turn, food consumption explained 97% of th...
