Litopenaeus vannamei outdoor culture device with aeration nanotubes connected with PVC (polyvinyl chloride) tubes

The invention discloses a litopenaeus vannamei outdoor culture device with aeration nanotubes connected with PVC (polyvinyl chloride) tubes. The litopenaeus vannamei outdoor culture device comprises a culture pond, a water inlet tube and a water outlet tube. A drain outlet is formed in the center of the bottom of the culture pond and is connected with the outlet tube. The litopenaeus vannamei outdoor culture device is characterized in that at least two layers of communicated PVC tube coils are arranged at the inner bottom of the culture pond, are outwardly uniformly distributed around the drain outlet and are elongated or circular; a plurality of communicated aeration nanotubes are uniformly distributed on the PVC tube coils at intervals in a connected manner and are communicated with the PVC tube coils, and the PVC tube coils are connected with roots blowers. The litopenaeus vannamei outdoor culture device has the advantages that the device is simple in structure and low in input cost, the concentration of underwater dissolved oxygen of the litopenaeus vannamei pond can be effectively increased, the water quality can be improved, diseases can be reduced, bottom fatal diseases can be effectively prevented, the culture density and the survival rate can be increased, and the purpose of high and stable yield can be achieved.
