The invention discloses a penaeus vannamei farming method combining bioflocculation technology and a multi-trophic-level integrated farming mode. The penaeus vannamei farming method combining the bioflocculation technology and the multi-trophic-level integrated farming mode includes the steps such as early-stage preparations of farming conditions, putting of penaeus vannamei and small-size fish, swamp cabbage planting, starch addition and feeding feedstuff management. According to the method, the multi-trophic-level integrated farming mode and the bioflocculation technology are innovatively applied to penaeus vannamei farming in a combining mode, namely, a multi-trophic-level integrated farming system composed of polyculture of the penaeus vannamei, the small-size fish and swamp cabbages. Starch is added in the farming system to serve as carbon source cultivation biological floccules. The levels of ammoniacal nitrogen and nitrous nitrogen in a water body are controlled through a bioflocculation action. Simultaneously, residual bait and excrement are utilized to form bacterium floccules which prawns and the small-size fish can ingest and utilize, and therefore the survival rate of the penaeus vannamei and the efficiency of feed utilization are improved. Relative to an ordinary single-farming mode, aspects of ecological benefits, economic benefits and farming effects in the farming system all achieve obvious effects.
