The role of microbial preparations in aquaculture

Water pollution control is one of the most difficult problems in aquaculture. It is well known that physical methods (such as salvage) can remove some pollutants, but it is difficult to deal with chemical pollutants such as ammonia nitrogen, nitrite and livestock manure. Chemical methods are also prone to secondary pollution. In recent years, microbial control pollution technology that can “eat” pollution has received increasing attention and has been widely used in fields such as sewage treatment.

Microbial preparations are harmless to the environment and promote the formation of biological chains. The area of ​​fish excreta produced by intensive high-density farming and the disease caused by untreated aquaculture wastewater and industrial wastewater pollution accounts for 15% to 20% of the total aquaculture area in aquaculture, and the concentration of ammonia nitrogen in these water bodies increases, resulting in Eutrophication of water bodies, in turn, restricts fish production. In order to reduce the harm caused by ammonia nitrogen pollution, the commonly used methods of adding new water and ozone oxidation have not only great limitations, but the deamination effect is not ideal and cannot solve the problem fundamentally. Therefore, improving the aquaculture water environment has become a key technology for the sustainable development of the aquaculture industry.

Aquatic microbial preparations can rapidly degrade residual feed in fish, fish manure and other organic matter, especially the bottom of pond water, which can effectively avoid the accumulation of solid organic matter and harmful substances. The photosynthesis produced by these algae-based phytoplankton provides oxygen to the aquatic animals in the pond, thus forming a benign ecological cycle of the pond. Promote the proliferation of beneficial microorganisms and form a dominant population in the pond, which can inhibit the growth of pathogenic microorganisms and reduce the occurrence of diseases.

At present, the application of domestic beneficial microorganisms in aquatic products is increasingly valued. The domestic independent development mainly includes some single strains, such as photosynthetic bacteria, Bacillus, Vibrio anguillarum, etc.; the composite preparations are mainly imitation or introduction of foreign commodities.
