At present, the situation of prevention and control of major diseases in China is more severe. The epidemic situation in some countries is obviously expanding, and the situation is very complicated. In some areas of China, poultry breeding methods are relatively backward, live poultry circulation and cross-regional transportation are frequent, and there are still some weak links in prevention and control. The task of prevention and control of infectious diseases in China is quite arduous. Epidemic diseases seriously affect the benefit of aquaculture. In view of the common problems in the large-scale development of aquaculture, the author systematically expounded and deeply analyzed seven natural animal diseases and epidemic human factors from environmental control, feeding management, disinfection, immunization, drug prevention, disease diagnosis and quarantine through long-term investigation and access to relevant materials. Aiming at the crux of the existing problems, the author analyzed the causes of the problems and put forward improvement measures and methods.
