At present, the application of Chinese herbal medicine bait in aquaculture has attracted some attention, and many experts in scientific research and universities in China have carried out research work in this field. Antibacterial Chinese herbal medicines not only have effects on bacterial diseases, but also have certain preventive and therapeutic effects on some viruses and fungi. The use of Chinese herbal medicine bait can not only improve the nutritional value of bait, but also has small toxic and side effects, short residual time, easy solubility in water and no pollution to the environment. They can be used together with antibiotics to play a certain auxiliary therapeutic role.

Chinese herbal bait is prepared by grinding Herba Andrographis, Folium Isatidis, Radix Isatidis, Cynanchum atratum, Radix et Rhizoma Rhei, garlic poison, and Herba Houttuyniae into powder, and adding them into feed separately or in combination. These Chinese herbal medicines can regulate the immunity of shrimp, have strong antibacterial ability, inhibit a variety of bacteria and enhance the phagocytosis of animal white blood cells. Many Chinese herbal medicines are broad-spectrum antibacterial agents, which can play a role that some antibiotics, chemical synthetic drugs, mineral elements and so on can not play. They are safe, affordable and reliable, and are worth popularizing.
