Specific dynamic action (SDA) of G. morhua at 6–7°C during digestion of 2% body mass pollock diet.

Fish were either exposed solely to normoxic conditions during the SDA (Normoxic) or exposed to 90 min of 35% O₂ saturation 2 h post-feeding and subsequently returned to normoxic conditions for the remainder of the SDA (Hypoxic). Values are mean±SE and n = 7 in both groups. A p-value greater than 0.05 indicates that there is no difference between the means of the variables.
