Abstract

Measurements of serum freezing points in three Antarctic marine fishes indicated that they do not freeze in the -1.87° C seawater because their blood is isosmotic to seawater. Concentrations of sodium chloride, urea, and free amino acids in the serum accounted for only half of the freezing-point depression of the serum. A protein containing carbohydrate was isolated which accounted for 30 percent of the freezing-point depression of the serum.
