Method for using Chinese herbal medicine to prevent fish disease in aquaculture

Abstract

The invention discloses a method for using Chinese herbal medicine to prevent fish disease in aquaculture. The method for using the Chinese herbal medicine to prevent the fish disease in the aquaculture includes steps that 1) preparing medicine, wherein the medicine is composed of 3 to 5 grams of sweet wormwood, 1 to 3 grams of common andrographis herb, 1 to 3 grams of fructus forsythiae, 2 to 5 grams of light yellow sophora root, 3 to 5 grams of Chinese thorowax root, 2 to 5 grams of eucalyptus leaf, 2 to 4 grams of Chinese gentian, 1 to 3 grams of Chinese mugwort leaf and 1 to 3 grams of apocynum venetum; 2) arranging a framework-shaped feeding region in a fishpond; 3) putting the medicine in a mesh bag to obtain a Chinese herbal medicine hanging bag; hanging the Chinese herbal medicine hanging bag on the framework-shaped feeding region, and controlling the depth of the Chinese herbal medicine hanging bag in the water. When feeding, most of fishes in the fishpond gather at the feeding region, and the fishes wear and collide the Chinese herbal medicine hanging bag to promote the release of the medicine in the Chinese herbal medicine hanging bag so as to prevent the fish disease.

Description

technical field [0001] The invention belongs to the technical field of prevention and treatment of aquatic animal diseases (fishery medicine), and in particular relates to a fish disease prevention and treatment method using herbal medicine in aquaculture. Background technique [0002] Existing aquatic medicine mainly is divided into three classes, and the one, chlorine preparation, as bleaching powder essence (disinfection dosage of fish pond is 20g / m 3 , the amount of control in the breeding pond is 0.4~0.8g / m 3 ), sodium dichloroisocyanurate (0.3~0.6g / m 3 ), trichloroisocyanuric acid (0.1~0.5g / m 3 ), chlorine peroxide (0.5~2.0g / m 3 ), etc., the main problem of the use of chlorine preparations is excessive chlorine caused by improper use; the second is antibiotics, such as chloramphenicol, nitrofuran, chloroform, colchicine, dapsone and metronidazole, etc., for the use of antibiotics The negative impacts of such drugs include the production of drug-resistant strains, r...

Problems solved by technology

[0002] Existing aquatic medicine mainly is divided into three classes, and the one, chlorine preparation, as bleaching powder essence (disinfection dosage of fish pond is 20g / m 3 , the amount of control in the breeding pond is 0.4~0.8g / m 3 ), sodium dichloroisocyanurate (0.3~0.6g / m 3 ), trichloroisocyanuric acid (0.1~0.5g / m 3 ), chlorine peroxide (0.5~2.0g / m 3 ), etc., the main problem of the use of chlorine preparations is excessive chlorine caused by improper use; the second is antibiotics, such as chloramphenicol, nitrofuran, chloroform, colchicine, dapsone and metronidazole, etc., for the use of antibiotics The negative impacts of such drugs include the production of drug-resistant strains, residual drugs in aquatic products, destruction of micro-ecological balance, and inhibition of the immune system; the third is insecticides, mainly including mercurous nitrate, trichlorfon, copper sulfate and Copper-iron mixture, zinc sulfate heptahydrate, phoxim, etc. The main problem is the occurrence of excessive heavy metals

[0003] At present, the method of preventing and controlling the pests and diseases of pond culture mostly adopts the method of spraying chemicals in the pond, but this method usually causes a large area of ​​fish stress response, thereby affecting the growth and wading of fish; and the drug dose required for spraying chemicals in the pond Larger, it is a greater economic burden for breeding enterprises; and due to the large amount of residues, it brings huge hidden dangers to food safety
