Disinfectant for water in grass carp and prawn mixed aquaculture ponds and method for applying disinfectant

Abstract

The invention discloses a disinfectant for water in grass carp and prawn mixed aquaculture ponds. The disinfectant comprises, by weight, 46-78% of potassium monopersulfate, 3-15% of malic acid, 2-10% of sodium chloride and 19-35% of coptis chinensis extracts. The potassium monopersulfate, the malic acid, the sodium chloride and the coptis chinensis extracts are uniformly mixed with one another to obtain the disinfectant. The invention further discloses a method for applying the disinfectant for the water in the grass carp and prawn mixed aquaculture ponds. The disinfectant for the water in the grass carp and prawn mixed aquaculture ponds and the method for applying the disinfectant have the advantages that main pathogenic microorganisms in the aquaculture ponds can be effectively killed, adverse effects on grass carps and prawns can be prevented, and the disinfectant is free of residues and pollution.

Description

technical field [0001] The invention relates to the technical field of water body disinfection and purification in aquaculture, in particular to a water body disinfectant for grass carp and prawn polyculture ponds and a use method thereof. Background technique [0002] China is a big aquaculture country. According to statistics, my country's aquaculture volume accounts for more than two-thirds of the world's total aquaculture. However, the problem of aquatic diseases has always been a serious problem hindering the healthy development of aquaculture industry; The incidence of aquaculture diseases is over 50%, and the loss rate is as high as 20%, causing direct economic losses of more than 10 billion yuan; Huge economic losses, among which the losses caused by viral diseases are also increasing; in the process of aquatic disease prevention and control, water disinfection is used to kill pathogenic microorganisms (viruses, bacteria, etc.) in water bodies or on the surface of farm...

Problems solved by technology

[0004] From the current point of view, there are still many shortcomings in existing disinfectants, such as chlorine-containing disinfectants are easily affected by changes in water organic matter and pH, and have a corrosive effect on instruments and are also highly toxic to fish; quaternary ammonium salts The bactericidal effect of iodine preparations is easily affected by water hardness; the effect of iodine preparations is easily affected by light, temperature and other conditions, and is prone to volatilization and failure (Huang Xiaoli and Deng Yongqiang, 2004); at the same time, most of the disinfectants currently used in production have a single type and a single preparation , Most of them come from human medicine, veterinary medicine and water treatment agents, and the disinfectants specially developed for aquaculture ponds and aquaculture animals are still very limited; especially in recent years, the polyculture model of grass carp and prawns has developed rapidly, Yet have not seen so far the disinfectant product that can be designed for the pond water body under the polyculture pattern condition of grass carp and prawn; Novel aquatic product disinfectant is general trend, also is the technical problem to be solved by the present invention
