AI Technical Summary

Problems solved by technology

At present, the prevention and treatment of this bacterial infectious disease mainly uses chemical drugs of antibiotics, but the chemical drugs of long-term use of antibiotics not only pollute the water body environment, but also cause re-injury to the fish body, reduce the natural immunity of the fish body, form drug residues, and make the disease more serious.
