Description

We examined post-exhaustive exercise recovery in Pacific cod acclimated to either 2°C or 7°C. We collected blood samples prior to an exhaustive swimming protocol, immediately after and up to four hours of recovery. Plasma concentrations of cortisol, glucose, lactate, Na⁺, and Cl^– were determined. Concentrations of cortisol, glucose, and lactate significantly increased post-swim as compared to samples collected pre-swim irrespective of temperature treatment. For either temperature treatment, sample concentrations of cortisol, glucose, and lactate of cod remained elevated and did not return to pre-swim levels after four hours of recovery.
