The Chinese herbal medicinal bait has the advantages of reasonable compatibility, balanced nutrition, low processing cost, good palatability and feed attraction property, high Ictalurus punctatus utilization rate, few metabolites, substantial improvement of the immunity of the Ictalurus punctatus, great reduction of the Edwardsiellasis infection probability of the Ictalurus punctatus, no drug residual or drug resistance, and good safety.

Description

technical field [0001] The invention relates to a Chinese herbal medicine bait for preventing and treating Edwardsiella disease of channel catfish and a preparation method thereof. Background technique [0002] channel catfish ( Ictalurus punctatus ), native to the Americas, also known as channel catfish, has the characteristics of fast growth, wide temperature range, and strong disease resistance. Channel catfish meat is tender, delicious, rich in protein and unsaturated fatty acids, and is deeply loved by consumers in the United States, the European Union and other countries.

Problems solved by technology

At present, the farms mainly feed chloramphenicol or tetracycline baits for 5 consecutive days. In addition, 1.5-2.0 mg / L (water) of furan is splashed outside the body to improve the therapeutic effect. The above-mentioned drugs are very easy to pollute the water body. Harmful to the environment, and the residual antibiotics in the fish are likely to make the eaters develop drug resistance and endanger human health
