| Abstract: | The adaptation of fish to temperature varies depending on their species as a result of long-term evolution and evolution.In this article two heat tolerance indices-the upper critical temperature and the initial high lethal temperature,as well as heat resistance related gene expression of different kinds of fish were summarized.And it was found that the important factors affecting the thermal tolerance of fish are the basal water temperature and the rate of temperature increase,as well as the physiology and genetics of the organisms,and then the thermal tolerance of different fish was grasped,gene hsp70 and caspase-3 apoptosis-related genes that were significantly differentially expressed under high temperature stress were analyzed and discussed,it was found that heat stress caused a significant increase in the rate of hsp70 synthesis in fish to improve their stress resistance,and also caused gene caspase-3 to be activated and induced apoptosis. |
