Advantages of using microorganisms in aquaculture

With the rapid development of aquaculture industry, the scale of industrial high-density aquaculture is expanding day by day, the pollution of aquaculture waters is becoming more and more serious, and aquatic animal diseases occur frequently, causing serious economic losses to aquaculture industry. At the same time, traditional disinfectants and antibiotics are no longer effective in preventing disease.

 

Advantages of microbial agents

Microorganism into the water, can effectively decompose ammonia hydrogen sulfide and other harmful substances, purify the water quality, improve the culture environment, increase the dissolved oxygen in the water, can effectively adjust the physiological function of fish, shrimp, crab, shellfish, enhance absorption and immunity, improve the survival rate and growth rate, improve the quality of fish, shrimp, crab, shellfish and so on, use ornamental fish appearance more bright.

1, reduce pathogenic microorganisms and bad algae, significantly enhance the immunity and disease resistance of culture objects, reduce the incidence of disease and improve the survival rate.

2, increase the number of beneficial microorganisms, zooplankton in the water, beneficial algae increase, to achieve the effect of fertilizing water.

3, stabilize and improve the water quality, water refreshing, no odor, no rot, no hydrogen sulfide, ammonia, etc.

4, fish, shrimp manure bottom impurities and residual bait will not become silt into loose sand, easy to decompose.

5, promote growth, weight gain rate increased significantly, products in advance to market, improve the yield per mu.

 

 

The role of common bacterias

When the bottom environment of aquaculture water deteriorates and the algae phase is not good, microbial microbial agent can be used. It can rapidly utilize macromolecular organic matter and mineralize organic matter into inorganic salts to provide nutrition for single-celled algae. The photosynthesis of single-celled algae provides oxygen for the oxidation of organic matter, microorganisms and aquatic animals.

The cycle is repeated to form a virtuous ecological cycle, so that the bacteria phase in the pond can achieve balance, maintain stable water color, and create a good bottom environment. At the same time of sprinkling bacteria agent, it is necessary to start the oxygenator as far as possible at the same time, so that it can reproduce in the water body and quickly form the population advantage.

However, sometimes often sudden changes in the environment will cause the occurrence of diseases, some of which are even uncontrollable. So, keeping water quality stable is sometimes more important than improving the environment itself. This requires us to create a good environment for them in the early stage of breeding, and then maintain this balance through various methods during the breeding process.

 

 

Bacterial agent use misunderstanding

 Only rely on the effectiveness of the speed to evaluate the quality of the product

Microbial life activities, in addition to decomposition of insoluble and fixed elements in aquacultural pond water, increase the supply of nutrient elements, use natural substances into substances necessary for the growth of algae in the water, promote the production of aquacultural varieties, but also can quickly cultivate beneficial algae and other plankton.

The effect of microbial fertilizer is closely related to the growth rate, number and growth cycle of microbial flora, which is the biggest difference between microbial fertilizer and chemical agents. This also leads to the phenomenon that the rapid effect of microbial fertilizer is inferior to that of chemical agents.

Slow response does not mean that the bacteriostasis is ineffective, can be seen in a relatively short time can be a significant improvement in the breeding pond is not necessarily a good product.

 One bacterium can solve many problems

A small number of farmers in the purchase of microbial agents only pay attention to whether live bacteria, and do not pay attention to the type of bacteria, lack of symptomatic bacteria awareness, product effect is difficult to play, difficult to achieve the purpose of use.

Different strains of bacteria have different functions. Microbial fertilizers can be used in five aspects: to provide nutrients; Nutrients that produce and promote the growth and reproduction of algae in the water; Improving aquatic product quality function; Enhance the resistance function of cultured varieties; Improving and repairing the function of aquaculture pond water body.

To combine the demand, the characteristics of strains, the function of strains to choose the right bacterial community.
