Abstract: In order to investigate the meteorological cause of the occurrence of Procambarus clarkii’s disease in Hubei province in recent years, the climatic conditions during the breeding stage of the main cultivation areas in Hubei were analyzed. The results showed that the production of P. clarkia had some correlation with the time of cold air’s occurrence, the duration and degree of low temperature, and the amplitude of temperature in March to June in spring season. The more frequent the cold air activities occurred, the more duration days of low temperature continued, the lower the temperature level was, and the greater the magnitude of temperate fluctuated, then the more serious the disease would occur, and this could be reflected in the production of the year. Therefore, the monitoring and forecasting onto the meteorological conditions in spring could provide decision making services for the cultivators of P. clarkia, in order to remind to take timely prevention and control measures to reduce the probability or extent of disease occurrence.
