Aquaculture method controlled by microorganisms

Abstract

The invention discloses an aquaculture method controlled by microorganisms. The method is characterized in that a composite microbial water quality modifying agent and water are uniformly stirred according to a mass ratio of 1:50, then the uniformly-stirred material is applied to a culture pond, wherein the use amount is 0.5-1 g/m<2>, and therefore the purposes of repairing water bodies and improving the survival rate and yield of aquaculture animals are achieved. The composite microbial water quality modifying agent is obtained by mixing 15-20% by mass of a composite microbial agent, 5-10% bymass of a nutritional agent and 70-80% by mass of a carrier, wherein the effective living bacterium quantity is 10<7>-10<8> cfu/mL, and performing fermentation. The composite microbial water qualitymodifying agent provided by the invention can effectively reduce the content of ammonia nitrogen and nitrite in the water bodies, increase a dissolved oxygen amount, eliminate odor of the water bodies, maintain balance of bacteria and algae, purify water quality, and reduce the disease rate and death rate of the aquatic animals, thereby improving a yield of aquaculture.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a microbe-controlled aquaculture method. Background technique [0002] At present, the following problems generally exist in the field of aquaculture: the alkalinity of aquaculture water is high or too strong, and the content of ammonia nitrogen and nitrite is high; Aging phenomena such as too thick water color, blackening, redness, and turbidity promote the growth of a variety of toxic pathogenic bacteria (such as Aeromonas hydrophila, Vibrio, Escherichia coli, Streptococcus, etc.) in the water body, resulting in aquaculture animals Diseases, such as: red legs, blind eyes, and rotten limbs in shrimp; black gills, swollen gills, rotten gills, blind eyes, broken whiskers, etc. in sea fish and freshwater fish; and low survival rates of other sea cucumbers and shellfish . This leads to low biological immunity, disease and fatality rates higher than 20%, seriously affecting the...

Problems solved by technology

[0002] At present, the following problems generally exist in the field of aquaculture: the alkalinity of aquaculture water is high or too strong, and the content of ammonia nitrogen and nitrite is high; Aging phenomena such as too thick water color, blackening, redness, and turbidity promote the growth of a variety of toxic pathogenic bacteria (such as Aeromonas hydrophila, Vibrio, Escherichia coli, Streptococcus, etc.) in the water body, resulting in aquaculture animals Diseases, such as: red legs, blind eyes, and rotten limbs in shrimp; black gills, swollen gills, rotten gills, blind eyes, broken whiskers, etc. in sea fish and freshwater fish; and low survival rates of other sea cucumbers and shellfish

This leads to low biological immunity, disease and fatality rates higher than 20%, seriously affecting the output of aquaculture, increasing the risk of the aquaculture industry, and causing a large loss of manpower and material resources. Therefore, how to control water quality problems in aquaculture and aquatic products? The problem of animal diseases is the focus of current research
