摘要
•The objective of the present study is to assess the effects of a gradual change in water temperature, an acute change in water temperature, and temperature fluctuations on physiological and biochemical responses, and Hsp70 expression in the Yesso scallop.•Results showed that physiological and enzymatic activities, and Hsp70 expression levels of P. yessoensis were clearly affected by acute water temperature changes and fluctuations.•The changes in physiological and biochemical responses of P. yessoensis will be an important reference for exploiting shellfish resources and optimizing their culture management.
