Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a method for rapid growth of fish. Background technique [0002] With the rapid development of the aquaculture industry, the problem of fish disease is becoming more and more serious, and has always been one of the main factors restricting the development of aquaculture. Drug resistance and the use of chemicals seriously pollute the bottom of the pond and produce harmful substances, and the harm of drug residues to the environment and human health is becoming more and more significant.

Problems solved by technology

However, compared with animal husbandry applications, the gap is still relatively large. The research on the efficacy, pharmacology, and toxicology of Chinese herbal medicines is still relatively shallow, and most of them follow or copy the methods of using livestock and poultry, resulting in unsatisfactory curative effects of Chinese herbal medicines on the prevention and treatment of aquatic animal diseases.

For example, due to the differences in the living environment, tissue and organ structure, and metabolism of fish and shrimp compared with humans and livestock, etc., prescriptions are effective in humans and livestock, and whether certain traditional Chinese medicines can play a role in prescriptions

Especially for shrimp, the length of the intestinal tract is shorter than the body length. Some fish have no stomach, so the active ingredients of ordinary Chinese medicine dissolve in the intestinal tract of fish and shrimp. The absorption time will be correspondingly reduced, resulting in that the drug effect cannot be fully exerted and it will be excreted
