Traditional Chinese medicine composition for preventing or treating ectoparasite of aquatic culture animals and preparation method and application thereof

Abstract

The invention discloses a traditional Chinese medicine composition for preventing or treating ectoparasite of aquatic culture animals and a preparation method and application thereof, and belongs to the field of traditional Chinese medicine insecticides for fishery. The traditional Chinese medicine composition comprises picrasma quassioides, cyrtomium fortunei and semen arecae. The traditional Chinese medicine composition has the significant effects of killing the ectoparasite of the aquatic culture animals. A benzalkonium bromide solution is added on the basis of the traditional Chinese medicine composition, therefore, not only can the efficiency of killing the ectoparasite of the aquatic culture animals be improved, but also the function of preventing secondary bacterial or fungal diseases from being infected by parasitic disease. The invention further discloses a preparation method of the traditional Chinese medicine composition; according to the method, extraction is performed with ethyl alcohol, the effective components of all the traditional Chinese medicines can be fully extracted, and therefore the medicine usage amount is decreased. The traditional Chinese medicine composition is plant-derived medicine, can prevent the medicine resistance from occurring, and is free of pollution to environment, convenient to use and stable in treatment effect.

Description

technical field [0001] The invention relates to a traditional Chinese medicine composition, in particular to a traditional Chinese medicine composition for preventing or treating ectoparasites of aquaculture animals. The invention relates to an application in medicine for parasites, and belongs to the field of traditional Chinese medicine insecticides for fishing. Background technique [0002] China's fish farming has entered a new era of large-scale and intensive farming, but the occurrence and damage of fish diseases are increasing, which restricts the healthy development of aquaculture. As one of the three major pathogenic diseases, parasitic diseases are becoming more and more serious due to changes in water quality and aquaculture environment. They are common and frequently-occurring diseases in aquaculture production and can occur throughout the year. If the treatment is not timely, It will cause the reduction or extinction of farmed fish production, and is one of the...

Problems solved by technology

The use of these pesticides and insecticides has the following problems: (1) Due to the increase of drug resistance, the dosage used in recent years has become larger and larger, such as the dosage of trichlorfon has changed from the initial 0.1 to 0.2mg / l, increased to the current 0.5-1mg / l; (2) Pesticides and insecticides are extremely toxic to farmed animals, such as deltamethrin for crustaceans such as shrimps and crabs, the semi-lethal dose is only 0.01mg / L; freshwater pomfret It is also sensitive to trichlorfon; (3) Drugs are prone to residues, which pose health threats to water bodies, farmed animals and even final consumers, and bury safety hazards for the aquaculture industry

[0004] In addition, parasitic infection often causes mechanical damage to the body and thus leads to secondary bacterial infection. Sometimes the harm of secondary bacterial infection is greater than the impact of parasitic infection itself, which will lead to accelerated onset
