Compound Chinese medicine micro powder and fish food for fish disease control

Abstract

This invention relates to a compound Chinese medicine micro powder and fish food for fish disease control, solving the problems of incapability of simultaneously controlling various fish diseases, dubious curative effect and easy generation of drug tolerance in current fish disease control. The compound Chinese medicine micro powder of the invention is obtained by carrying out ultramicro grinding on the following raw materials in parts by weight: 9-15 parts of folium isatidis, 6-9 parts of folium cortex eucommiae, 9-12 parts of ginkgo leaves, 3-9 parts of scutellaria baicalensis and 4.5-9.0 parts of radix sophorae flavescentis. The fish food for fish disease control of the invention contains 4%-6% of the compound Chinese medicine micro powder for fish disease control by weight percent. The compound Chinese medicine micro powder can control various fish diseases caused by various infectious agents, has confirmed curative effect, can improve fish immunity and promote growth and development, does not generate drug tolerance, and has no toxic or side effect. The fish food of the invention has good taste, thus fish schools like to eat the fish food.

Description

technical field [0001] The invention relates to a compound traditional Chinese medicine micropowder for preventing and treating fish diseases and fish feed containing the compound traditional Chinese medicine micropowder. Background technique [0002] As fish farmers pursue higher production, arbitrarily increase the breeding density, coupled with serious environmental pollution, neglecting the prevention and control of fish diseases, it is easy to cause various diseases of fish, such as hemorrhagic disease, sepsis, sepsis Wait. The epidemic season of this kind of disease is long from the end of February to November, and the water temperature is between 9 and 36 °C. It is especially serious when the water temperature is above 28 °C and after the high temperature season. The harmful freshwater cultured fish are: heterogeneous Gibel crucian carp, white crucian carp, crucian carp, bream, silver carp, bighead carp, carp, dace, eel, California perch, bream, etc. The survey show...

AI Technical Summary

Problems solved by technology

Because (1) the fish pond is an open and exposed system, coupled with water pollution and the extensive use of antibacterial drugs, there are a considerable number of bacteria, viruses, bacterial endotoxins, fungi, parasites and other pathogens in the water of general fish ponds. In summer, we The bacterial endotoxin content in the water of many fish ponds in the urban area of ​​Wuhan was measured, and the results found that the bacterial endotoxin content remained as high as 20-30EU / mL. The high content of bacterial endotoxin in the environment is one of the important causes of fish disease. 1; (2) Not only that, various diseases of the fish body may be co-infected with bacterial endotoxins, such as parasites, etc., which may cause ischemia, necrosis, and barrier destruction of the gastrointestinal mucosa of the fish body. At the same time, a large amount of endotoxins will enter the blood, Form endotoxemia; when fish are infected with pathogenic bacteria, the pathogenic bacteria will also release bacterial toxins to harm the fish body, etc. Ineffective, bacterial endotoxins will be released when the bacteria die and crack. The greater the amount of antibacterial drugs used, the more bacteria are killed, and the more bacterial endotoxins will be released, which will cause the spread and aggravation of fish diseases. It can lead to fish hemorrhagic disease, septicemia, sepsis and other fish diseases that cannot be cured for a long time

[0004]In addition, in the current prevention and control of fish diseases, managers need to carefully identify which pathogens fish are infected with according to different pathogens, so as to target different diseases Choosing antiviral or antibacterial drugs requires extensive experience or scientific instruments for testing, which brings about relatively high requirements for managers’ experience, complicated treatment process, and inaccurate curative effects

Moreover, the western antibacterial, antiviral or antiparasitic drugs used in large quantities in the treatment are also easy to accumulate in the fish body and produce drug resistance. After human consumption, it will not only affect the taste, but also bring various hazards to the human body
