The use of broad-spectrum antibiotics to control the occurrence of diseases not only increases bacterial resistance, destroys and interferes with the normal biological fauna of the farming environment, resulting in microbial ecological imbalances, but also leaves residual antibiotics in aquatic products and endanger human health. serious
