Closed type zero-emission industrialized tilapia culture method

The invention relates to a closed type zero-emission industrialized tilapia culture method. The closed type zero-emission industrialized tilapia culture method comprises the following steps: regulating the pH value, total alkalinity and total hardness of a culture water body to required ranges before fry stocking, culturing a denitrification type biological floccules, then carrying out stocking, and carrying out management. The tilapia cultured by using the method provided by the invention grows well; meanwhile, the closed type zero-emission industrialized tilapia culture method provided by the invention avoids culture problems like poor water color, long-term excessiveness of ammonia nitrogen and nitrite, high level or intense change of a pH value, blue-green algae propagation, widespreadparasites, long-term turbidity of a water body, serious pollution and frequent diseases and pests caused by unbalance between carbon and nitrogen. 本发明涉及种封闭式零排放工厂化罗非鱼养殖方法，在放苗前先将养殖水体pH、总碱度、总硬度调至要求范围，再培育出脱氮型生物絮团，然后放苗并进行管理，经该方法养
