Application method of synthetic microbial community inoculant for aquaculture

The invention discloses a use method of a synthetic microbial community microbial inoculum for aquaculture, and relates to the technical field of aquaculture, bacillus subtilis is used for consuming oxygen to provide a micro-aerobic environment for lactic acid bacteria, the lactic acid bacteria grow to produce lactic acid, a strict anaerobic environment and a lactic acid substrate are provided for the growth of clostridium butyricum, and the growth of clostridium butyricum is promoted. Clostridium butyricum generates short-chain fatty acid butyric acid, inhibits reproduction of bacteria and parasites, nourishes and repairs intestinal cells, inhibits pathogenic bacteria, and adjusts animal immunity and inflammatory response; the clostridium butyricum and the lactic acid bacteria not only have the intestinal probiotic function, but also can be subjected to anaerobic propagation in bottom mud of a water body, inhibit propagation of pathogenic bacteria in the water body, decompose pond sludge, residual feed, excr
