Problems solved by technology

In recent years, the scale of crayfish farming has been expanding year by year. In order to increase the output of crayfish and reduce the incidence of disease, crayfish feed additives have been continuously developed, but most of them contain many chemical substances. Additives not only affect the meat quality of crayfish, but also cause irreversible harm to the quality of rice fields. The most important thing is that the food safety of the people cannot be guaranteed
