Intensive high-density circulating aquaculture system of penaeus vannamei

Abstract

The invention discloses an intensive high-density circulating aquaculture system of penaeus vannamei. The aquaculture system comprises an aquaculture tank, a sediment tank, a micro-filter tank, a floatation tank, a water lifting tank, a biofilter, an emergency reserve tank and a sterilization and aeration tank in the water flowing direction. The aquaculture system uses technologies in the fields of physics, chemistry, biology and the like, adopts a PLC automatic control technology and a microbiological treatment technology, and takes measures such as physical mechanical filtration, protein separation, biological membrane treatment, sterilization and aeration on aquaculture water, so that cyclic utilization of 95% or above of the whole aquaculture water body is basically achieved, it is basically achieved that the aquaculture water body can be recycled and controlled and the whole aquaculture process is green, environmentally friendly, healthy and safe, and the intensive high-density circulating aquaculture system of penaeus vannamei provides exploration and demonstration for achievement of circular economy and sustainably developed fishery engineering with modern facilities.

Description

technical field [0001] The invention belongs to the technical field of aquatic product cultivation, and in particular relates to an intensive high-density circulating aquaculture system of Penaeus vannamei. Background technique [0002] Penaeus vannamei, also known as white-limbed shrimp and white-legged shrimp, is one of the three largest shrimp species in the world with the highest aquaculture output. Adults can be up to 24cm long, with a thin carapace. The normal body color is light blue-gray, and there are no markings on the whole body. Penaeus vannamei has a thin shell and fat body, delicious meat and rich nutrition. It is an extremely popular seafood in the market. Internationally, China's shrimp export has also formed a scale advantage. With the improvement of people's living standards and the further development of logistics, the market area of ​​Penaeus vannamei will continue to expand and its potential will be further stimulated. [0003] The traditional vannamei...

Problems solved by technology

However, the biggest disadvantage of extensive farming in earthen ponds is that the bottom of the pond is easy to accumulate breeding waste, which becomes a nutrient for the proliferation of pathogens. The disease of Penaeus vannamei is difficult to control, and the risk of breeding is high. Generally, it is not suitable for high-density farming.
