Abstract
THE property of the blood of fish to clot rapidly provides a means of protection from fatal hæmorrhage such as may follow injuries1. Sometimes in the same fish the blood clotting-time is known to differ markedly at two different phases of its life-cycle. In the pre-spawning phase when the fish is fully laden with reserves, blood clotting is almost instantaneous, whereas during the period of physiological stress which generally follows spawning, clotting is slow and prolonged. Such variations in the coagulation-time have been attributed to some unknown factors which may involve a change in the chemistry of the blood of fishes2.
