Problems solved by technology

[0002] my country is the only country in the world where the output of aquaculture is higher than that of fishing. The large-scale, high-density, and intensive farming model has caused various fish diseases to become more and more serious. Various antibiotics are widely used in aquaculture to prevent diseases and improve feed quality. Utilization rate and promotion of animal growth. Due to the general lack of guidance and constraints of laws and regulations in the process of production and use, the abuse and illegal use of antibiotics is serious. On the one hand, it causes pollution to the aquatic ecological environment, on the other hand, it leads to Drug residues, passing through the food chain, threaten human health
