Problems solved by technology

[0004] With the continuous expansion of aquaculture scale and continuous improvement of aquaculture density, the self-purification and adjustment capabilities of aquaculture water in my country can no longer meet the needs of removing residual bait and fish and shrimp excrement, resulting in ammonia nitrogen, nitrate, nitrite, and sulfide in aquaculture water. seriously exceeded the standard, the water quality deteriorated, and fish and shrimp diseases occurred frequently
At the same time, the large and frequent use of antibiotics also has a great impact on the quality and export of aquaculture animals
At present, the application of a single probiotic strain in the aquaculture industry still cannot effectively improve the water quality and the occurrence of fish and shrimp diseases

Abstract

The invention discloses a novel environment-friendly efficient microorganism water quality purifying mixture and a preparation method thereof. The microorganism water quality purifying mixture is a mixed microorganism bacterial agent mainly consisting of high-concentration bacillus subtilis liquid and high-concentration bdellovibro bacteriovorus liquid, and is prepared from the following raw materials in percentage by volume: 10-50% of bacillus subtilis liquid, 20-60% of bdellovibro bacteriovorus liquid, 0.5-6.0% of normal saline and 0.5-15% of trace element solution. The novel environment-friendly efficient microorganism water quality purifying mixture disclosed by the invention integrates the advantages of the bacillus subtilis in purifying water quality and the bdellovibro bacteriovorus in preventing and treating diseases, has the functions of purifying water quality, preventing and treating diseases and replacing antibiotics, and realizes a function of improving the water for aquaculture.

Description

technical field [0001] The invention relates to a novel environment-friendly microbial water purification mixture and a preparation method thereof, which can be used for aquaculture, water quality purification, environmental protection and the like, and belongs to the technical field of aquaculture water body improvement. Background technique [0002] Since the 20th century, my country's aquaculture industry has made great progress. However, with the continuous expansion of the scale of aquaculture and the continuous improvement of the degree of intensive farming, the degree of eutrophication in aquaculture ponds is getting higher and higher. Since the self-purification and adjustment ability of the aquaculture water body can no longer meet the needs of removing residual bait and fish and shrimp excrement, the ammonia nitrogen, nitrate, nitrite, and sulfide in the aquaculture water body seriously exceed the standard, the water quality deteriorates, and fish and shrimp disease...
