Microorganism preparation for purifying aquatic product cultivating water body and preparation method thereof

Abstract

The invention discloses a microbe agent for purifying aquaculture water mass and a method for preparation, which belongs to the aquaculture water mass technique field. The agent comprises the following parts by weight: bran 80-90%, chaff 3-15%, glucose 2-5%, alta-mud 1-5%, K2HPO4 1-3% and VD 0.01-0.10%, wherein equal quantity of water is charged to dispense the solid culture medium, the preservation number is CGMCC No.2288, the germ is Bacillus subtilis BJ which is prepared by classes of fermentation. The agent is cheap in cost, high in bacterial content and the quality assured period is over one year and a half, the pH value of culture period water mass is between 8.02 and 8.60 stably after using, ammonia nitrogen can be reduced to safe level after 5-7 d, nitrite can be maintained in the safe density, the culture success rate can be improved greatly and can be spreaded and used in the aquaculture places.

Description

technical field [0001] The invention relates to the technical field of aquaculture water, in particular to a microbial preparation for purifying aquaculture water and a preparation method thereof. Background technique [0002] "Fish farming first raises water", water quality is the key to the success or failure of aquaculture. However, with the development of intensification and large-scale production of aquaculture, the aquaculture industry is facing a series of serious problems: deterioration of water quality, frequent outbreaks of diseases, proliferation of harmful algae, abuse of chemicals, and decline in the safety of aquatic products. Among them, the deterioration of water quality is the most fundamental of all problems. It is precisely because of the deterioration of water quality that frequent outbreaks of aquatic animal diseases have been aggravated, and the abuse of chemical drugs such as antibiotics has been exacerbated, resulting in a decline in the safety of aq...

Problems solved by technology

[0005] The purpose of the present invention is to aim at the low number of effective viable bacteria and large usage in the existing similar bacterial agent technology; the preservation of liquid products is easy to be contaminated with bacteria, and transportation is inconvenient; the cost is too high due to raw materials and production methods High, high product prices and other defects, propose a microbial preparation that can quickly decompose organic matter, efficiently degrade ammonia nitrogen, nitrite, inhibit the growth of harmful algae, achieve the purpose of purifying and repairing water quality, and improving aquaculture benefits; Another purpose of the present invention is Provide a kind of preparation method of this microbial preparation
