We examined the effect of an artificial change of water temperature on the survival rate of Korean Scallop, Patinopecten yessoensis. As for the change of water temperature, the aspects appearing on the eastern coast of Korea during spring and summer were artificially prepared in the rearing aquarium in the laboratory. The survival rate of Scallop, due to the stimulus of a low water temperature in spring, was an average of 51.6%. Medium-sized scallops averaged 4.4%, which is lower than that of small-sized ones (85.82%) and large-sized ones (55.0%). The survival rate of Scallop, due to the stimulus of water at a high temperature in summer, was an average of 43.3%. As for small-sized scallops, they averaged a 46.7% survival rate which is lower than that of medium-sized scallops (60.0%). In general, the survival rate was lower in summer than in spring. Such results show that the death of Scallop, has close relevance to the change of water temperature. The low survival rate of medium-sized ones. Alternatively, medium-sized scallops have to get through winter, even if they cannot grow enough compared with large-sized ones. This is because large-sized scallops have already been adapted to the change of water temperature by getting through winter twice.
