Microecological preparation for purifying water quality in litopenaeus vannamei culture and preparation and application thereof

Abstract

The invention provides a microecological preparation for purifying water quality in litopenaeus vannamei culture and preparation and application thereof, and relates to aquaculture. The microecological preparation for purifying water quality in litopenaeus vannamei culture contains at least one kind of materials from bacillus subtilis, bacillus pumilus and at least one kind of materials from lactobacillus plantarum and lactobacillus acidophilus; the microecological preparation for purifying water quality in litopenaeus vannamei culture comprises veterinary medicine, feed additives or water quality purification agents and the like. The preparation applied to the litopenaeus vannamei culture is concretely a preparation prepared from bacillus subtilis, bacillus pumilus, lactobacillus plantarum and lactobacillus acidophilus, and is applied in aspects of promoting litopenaeus vannamei growth, improving the immunity and the disease resistant capability, improving the litopenaeus vannamei culture survival rate, simultaneously reducing the ammonia nitrogen in the culture water body and purifying the culture water quality.

Description

technical field [0001] The invention relates to aquaculture, in particular to a microecological preparation for purifying water quality in Litopenaeus vannamei culture, a preparation method and application thereof. Background technique [0002] Since 2003, with the promotion of high-density farming mode, my country's shrimp farming industry has entered a period of rapid development. In 2006, the total amount of shrimp farming in my country was 1.25 million tons, accounting for 39.2% of the global farmed shrimp production, and it has remained the world's first for many years . However, the rapid development of intensive and high-density aquaculture has seriously damaged the ecological environment of aquaculture, and also produced a series of negative effects, including waste of feed resources, environmental deterioration, serious diseases, germplasm degradation, drug residues, etc. , especially disease problems are becoming more and more serious. Shrimp white spot virus, tau...

AI Technical Summary

Problems solved by technology

In the high temperature season of late spring and summer every year, various acute infectious diseases often break out, such as nerve necrosis virus, iridescent virus, vibrio and other pathogenic bacteria, which cause a large number of deaths of shrimp seedlings and juvenile shrimp, bringing huge economic losses to farmers , seriously restricting the development of shrimp farming

According to statistics, the annual mortality rate of prawn seedlings is as high as 80%. At present, in order to maintain the breeding density and prevent the outbreak of diseases in the process of prawn farming, various antibiotics are blindly used in production, such as chloramphenicol, oxytetracycline, and furazolidone. etc., resulting in severe drug residues in the body of farmed animals, which has brought potential harm to the health of farmed animals and humans
