Abstract
The invention relates to a microbial preparation for ecological breeding of penaeus vannamei boone and a preparation method of the microbial preparation. The microbial preparation is formed by compounding bacillus subtilis with a water purification function, lactobacillus acidophilus and beneficial algae. The beneficial algae used in the invention comprise any one of cyanophyta, bacillariophyta, chlorophyta and chrysophyta.
Description
Technical field
The invention belongs to agricultural application microbial technology field.
Background technology
Shrimp culture industry occupies critical role in culture fishery.Shrimp culture industry once peaked in the early 1990s, but perplexed by disease afterwards, and output zhang width declines.In the world, the greatest danger that the development of prawn culture fishery and cultivation ability thereof face is day by day serious ecotope and pathologic problems, high-density breeding technology creation has gone out highly manual environment, this environment promotes bacterial growth, the selection of bacterium is evolved and creates disadvantageous effect: dissimilar water treatment, as mocromembrane filters and uviolizing, make seawater before being used to larya culturing, change microorganism species composition: the high-density young caused due to a large amount of Live food of throwing something and feeding, dead young remains, the high loading of organism and bacterium, have stimulated selective action, make the conditioned pathogen raised growth in aquaculture water.If now immunity of prawn weakens, disease will break out.The factors such as the continuous deterioration of shrimp disease and breeding environment, antibiotic abuse, irrational high-density breeding, prawn germ plasm resource is damaged, shrimp body disease resistance weakens have direct relation. and wherein environmental factors plays an important role.Disease of prawn break out be more cause disruption of ecological balance due to the destruction of the ecosystem and the increase of breeding density composite factor caused by.For shrimp culture industry, key improves breeding environment, improves prawn to the resistibility of disease.And probiotics both can purify water, environmental protect, prawn immunological competence can be improved again, there is good prospect in prawn culturing.
Summary of the invention
