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

Abstract

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.

Description

technical field [0001] The invention relates to an aquaculture device connected with a nano aeration pipe and a PVC pipe, in particular to an outdoor culture device of Penaeus vannamei connected with a nano aeration pipe and a PVC pipe. Background technique [0002] Penaeus vannamei, also known as Litopenaeus vannamei, is one of the three high-quality and high-yielding shrimp cultured species recognized in the world today. Penaeus vannamei has the characteristics of wide temperature, wide salinity, suitable for high-density farming, and good product sales. This shrimp species has been rapidly promoted worldwide and has become a hot spot in the world aquaculture industry. Both seawater and freshwater aquaculture have achieved remarkable benefits, and their aquaculture area, output, and benefits have far exceeded other aquaculture species. However, under high-density breeding conditions, it is easy to cause hypoxia at the bottom of the water body, and insoluble organic matter...

Problems solved by technology

However, due to the gap in the production process of the current nano-aeration tube, it is mainly reflected in the service life and effective aeration volume, and its price also varies greatly.

At present, the price of domestically produced nano-aeration tubes is generally 1.5-10 yuan / m. The main feature is that the price is acceptable to the majority of farmers, but the service life is too short and the replacement is more frequent. The imported high-end nano-aeration tubes , it has a longer service life, but most of the prices are above 50 yuan / m, or even more than 100 yuan per meter, which adds a large cost burden to the majority of farmers on the inflatable device. At the same time, the current nano-aeration Uneven tube aeration is not conducive to the large-scale and sustainable development of Penaeus vannamei aquaculture
