Abstract

THE blood serum freezing points of most marine teleosts are within the range of -0.5 to -0.8° C1. As large regions of the oceans have temperatures as much as 1° C below this range2, many marine fish must either increase the osmotic concentrations of their blood or exist in a supercooled state. The latter is unstable and in the presence of ice, supercooled fish will freeze and die.
