Effects of warm acclimation on serum osmolality, cortisol and hematocrit levels in the Antarctic fish, Trematomus bernacchii

Antarctic fish, such as the Trematomus bernacchii , living at −1.9°C maintain a serum osmolality of around 600 mOsm kg −1 , nearly twice that of temperate fish. Upon warm acclimation, Antarctic fish significantly lower their serum osmolality. It has been suggested that this response to warm acclimat...
