GROWTH AND IMMUNE RESPONSE OF PROCAMBARUS CLARKII IN HIGH-TEMPERATURE AQUACULTURE ENVIRONMENT UNDER CLIMATE CHANGE

Global climate change has a significant impact on aquatic ecosystems, especially on aquaculture.Summer high temperature stress is the main environmental factor affecting its aquaculture efficiency and biological safety.In response to this issue, this study proposes a series of evaluation methods to determine the most suitable growth temperature and dissolved oxygen concentration, and optimize aquaculture conditions.In the experiment, the water temperature was controlled within the range of 5 to 25, and the dissolved oxygen concentration was adjusted.The weight growth of Procambarus clarkii was observed, and specific growth rates and other indicators were used as evaluation criteria.At 25, the weight gain effect of Procambarus clarkii was particularly prominent, indicating that this temperature range was most suitable for its growth.The digestive enzyme activity test showed that the digestive enzyme activity reached its peak at 20, and the appropriate water temperature significantly increased the digestive enzyme activity.This study clarifies the importance of appropriate water temperature and light conditions for the growth and immune response of Procambarus clarkii, which helps to ensure the breeding efficiency and biological safety of Procambarus clarkii.
