What is the cause and treatment of crab death in June?

June is the transition period from Huangmeitian to high temperature period, and the pond management at this stage directly affects the pond environment in high temperature period.

There were many rainy days in June, and the pond was in a state of hypoxia for a long time. The water quality in this period is very suitable for the reproduction of some anaerobic pathogens in water, that is, the incubation period of pathogens. With the arrival of high temperature period, river crabs began to die, especially in ponds that often lack oxygen, and cyanobacteria died more seriously. Therefore, June is also the best period for disease prevention.

Regular disinfection of ponds (10- 15 days/time) can effectively inhibit the propagation of pathogenic bacteria in ponds. In addition, it is also an important means to transform the bottom, reduce harmful bacteria at the bottom and improve the resistance of river crabs.
