[0002] Crayfish is a kind of freshwater economical shrimp. It is widely welcomed by people because of its delicious meat. Because of its omnivorous nature, fast growth speed and strong adaptability, it has formed an absolute competitive advantage in the local ecological environment. In recent years, it has become an important economic breeding in China. Variety, in recent years, with the sharp increase in market demand, the market price has increased year by year, which has stimulated the enthusiasm of the masses to raise crayfish, and the enthusiasm for breeding has increased. However, the current crayfish farming technology is not yet fully mature. The core technologies of key links such as daily management and shrimp disease prevention and control have not been fully popularized, and extensive and empirical farming is still the mainstay, and production is extremely unstable. At the same time, due to the strong environmental adaptability of crayfish, many commercial crayfish on the market are produced in Growing in a heavily polluted environment, there are serious quality problems, threatening people's health, and seriously affecting the development of industrialization and large-scale farming of crayfish
