Summary

PACIFIC HERRING, CLUPEA HARENGUS PALLASI, WERE COLLECTED AT 3 LOCATIONS IN ALASKA AND JAPAN IN WINTER AND SPRING TO DETERMINE THEIR DEGREE OF FREEZING RESISTANCE. HERRING COLLECTED FROM WATERS WHOSE TEMPERATURES RANGED BETWEEN 277.85 AND 271.75 K (4.7 AND -1.4 DEG C) SHOWED SERUM FREEZING POINTS BETWEEN 271.9 AND 271.75 K (-1.22 AND -1.40 DEG C).ALL FREEZING POINTS WERE BELOW THOSE EXPECTED FROM MEASUREMENTS OF SERUM OSMOLALITY, INDICATING THAT A NONCOLLIGATIVE ANTIFREEZE WAS PRESENT THAT ADDED BETWEEN 0.28 AND 0. 61 K TO THE FREEZING POINT DEPRESSION.
