Composite microbe agent for aquatic product culture and application thereof

Abstract

The invention discloses a composite microbe inocula for aquatic product culture and application thereof. The inocula is compose of five floras as follows: Bacillus laterosporus, Bacillus licheniformis, Streptococcus faecium, Bacillus subtilis and Saccharomycetes, and the five floras are mixed by weight according to the ratio: 1-4 parts of Bacillus laterosporus, 2-5 parts of Bacillus licheniformis, 0.8-2 parts of Streptococcus faecium, 2-4 parts of Bacillus subtilis, 0.2-1 parts of Saccharomycetes. The product has the advantages of good stability and high efficiency, extreme low oxygen consumption in the application process, rapid settlement to the water body bottom, rapid degradations of residual bait, night soil, biological residual body and other organic pollutants in water body, effective improvement of water body bottom environment, and substantially reduction of contents of ammonia nitrogen and nitrite in culture water body. The invention has the advantages of nontoxicity and innocuousness for environment and human and animal without residual, and can substantially improve the sediment and purify the culture water body environment, and simultaneously can improve the immunity of aquatic animal and reduce incidence of disease.

Description

technical field [0001] The invention belongs to the technical application field of aquaculture microorganisms, and in particular relates to a composite microbial bacterial agent for aquaculture, and also relates to an application of the composite microbial bacterial agent for aquaculture. Background technique [0002] Since the 1980s, the intensive aquaculture model has developed vigorously in my country, which largely meets people's demand for aquatic products and solves the problem of relative shortage of natural fishery resources. However, the pollution caused by the rapid development of the aquaculture industry has put a lot of pressure on the water environment of most rivers and lakes in our country. of sustainable development. For example, at present, the high-density pond breeding method commonly used in China has brought many problems and disadvantages while increasing the output of aquaculture products, such as feed residues, excrement of fish, shrimp and crabs, de...

But there is certain limitation in the substrate improving agent used now, as the application number is 02129886.6 title and is called the patent of " improving agent of coastal seabed soil and water quality " and adopts dolomite, shellfish powder, slaked lime or quicklime to make, but dolomite and Quicklime, slaked lime, etc. are all non-renewable resources and must be purchased before they can be used; the patent application number 03126702.5 discloses "a kind of improvement agent for the bottom ecological environment of aquaculture ponds and its use method", and the bottom quality improvement agent is made of chitosan Sugar, fulvic acid, sodium humate and bentonite are four kinds of raw materials. The powder product made of four kinds of raw materials, when used, the product is adjusted into a suspension and sprinkled on the pond. It mainly works in the water body, and cannot reach the bottom of the pond well. Effect; the patent application number 201010615829.4 discloses "substrate improver", the main components of the substrate improver are Bacillus subtilis, Bacillus licheniformis, Sporidium thermophila, Trichoderma konshii, Chrysosporium plain leather Bacteria, the total content of bacteria is 4 to 3 billion / g, the content of bacteria is low, and the substrate cannot be completely improved
