Problems solved by technology

[0003] According to existing reports, the structure and composition of bioflocs is quite complex, and its formation mechanism is not completely clear. The academic community generally believes that the formation of flocs is mainly caused by algae or bacterial flocculation.

Embodiment 1

[0020] The mass percent content of each component of the biofloc culture medium in this example is: soybean honey and sucrose molasses 70%, gorgon powder and wheat bran powder 20%, lactic acid bacteria 5%, potassium dihydrogen phosphate and calcium dihydrogen phosphate 5% .

[0021] The application of the biofloc culture medium of this embodiment in the tilapia culture water body:

[0022] Put quicklime, disinfectant, calcium chloride, magnesium sulfate, and baking soda into the culture pond in turn to keep the pH at 8.0-8.2; the total alkalinity at 120-200ppm; the calcium ion concentration at 72-120ppm; the magnesium ion concentration Keep at 40-100ppm; ammonia nitrogen concentration below 0.2ppm; nitrite concentration below 0.02ppm. On the second day after adjusting the water quality index, add the biological denitrification agent and the biofloc culture medium of this embodiment to the breeding pool respectively, and sprinkle the whole pond after turning the water into wat...

Embodiment 2

[0025] The mass percent content of each component of the biofloc medium in this example is: soybean honey and sucrose molasses 90%, gorgon powder and wheat bran powder 8%, lactic acid bacteria 1%, potassium dihydrogen phosphate and calcium dihydrogen phosphate 1% .

[0026] Put quicklime, disinfectant, calcium chloride, magnesium sulfate, and baking soda into the culture pond in turn to keep the pH at 8.0-8.2; the total alkalinity at 120-200ppm; the calcium ion concentration at 72-120ppm; the magnesium ion concentration Keep at 40-100ppm; ammonia nitrogen concentration below 0.2ppm; nitrite concentration below 0.02ppm. On the second day after adjusting the water quality index, add the biological denitrification agent and the biofloc culture medium of this embodiment to the breeding pool respectively, and sprinkle the whole pond after turning the water into water, so that the concentrations of the biological denitrification agent and the biofloc culture medium are equal. Then ...

Abstract

The invention relates to a biofloc medium. The biofloc medium is prepared from soy honey, sucrose molasses, thickening starch, wheat bran powder, lactic acid bacteria, monopotassium phosphate and monocalcium phosphate. Good bacteria such as ammonifiers, nitrite bacteria, nitrifying bacteria, denitrifying bacteria and the like can be cultured in a water body by the biofloc medium under the condition of proper total alkalinity and hardness, stable denitrifying biofloc can be formed and has stable and efficient denitrifying capacity as well as assimilation and dissimilation functions, so that waste nitrogen in water can be discharged in the form of nitrogen, the water body is cleaned, a system is stabilized, disinfection and killing drugs are not used in the whole process, and green cultivation and zero-pollution discharge are realized truly. Cultivation difficulties such as bad water color, long-term standard exceeding of ammonia nitrogen and nitrite, staying at a high level or intense varying of pH, blue-green algae breeding, parasite flooding, long-term turbidity of the water body, serious pollution, multiple diseases and the like of the water body due to carbon-nitrogen imbalancecan be prevented and treated by using the biofloc medium regularly.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a biological flocculation culture medium. Background technique [0002] Bio-floc technology (BFT) is based on the activated sludge technology in urban sewage treatment, by artificially adding organic carbon substances (such as molasses, glucose, etc.) Increase the number of heterotrophic bacteria in the water body, use microorganisms to assimilate inorganic nitrogen, convert ammonia nitrogen and other nitrogen-containing compounds in the water body into bacterial proteins, and form biological flocs that can be directly ingested by filter-feeding breeding objects, which can solve the problem of spoilage in aquaculture water. It is a technology that eliminates the problem of crumbs and feed retention, realizes the reuse of bait, purifies water quality, reduces the amount of water exchange, saves feed, improves the survival rate of breeding objects, and increases pro...
