Whiteleg shrimp high-density non-water-replacement breeding method based on nitrobacterium cenobium water quality control

The invention discloses a whiteleg shrimp high-density non-water-replacement breeding method based on nitrobacterium cenobium water quality control. The method includes the following steps of firstly, preparing a breeding pond; secondly, disinfecting the breeding pond and culturing probiotics; thirdly, stocking shrimp larvae; fourthly, putting in feed; fifthly, monitoring and managing the water quality of the breeding pond; sixthly, conducting harvesting. According to the method, by reasonably controlling organic carbon source input, scientifically applying beneficial bacterium preparations such as nitrobacterium, bacillus, lactic acid bacteria and photosynthetic bacteria, culturing the microorganism cenobium, namely the nitrobacterium cenobium, with nitrobacterium as the advantage in an oriented mode in the breeding water environment and meanwhile reasonably controlling the concentration of nitrobacterium cenobium and conducting in-situ biological purification on ammonia nitrogen and nitrite, closed type safe and efficient breeding of whiteleg shrimps is achieved.
