Seasonal changes in the plasma levels of glycoprotein antifreeze, Na + , Cl − , and glucose in Newfoundland Atlantic cod ( Gadus morhua )
A seasonal study was carried out on the hematocrits, plasma freezing point depression, and thermal hysteresis, and plasma Na + , Cl − , total protein, and glucose concentrations in laboratory maintained Atlantic cod. Significant thermal hysteresis was evident in the plasma during the months of Janua...
