technical field

The invention relates to a flowing water aquaculture system, specifically a back-suction flowing water aquaculture system arranged on the surface of a water body. Aquatic animals are cultured in high density in the aquaculture system, and the power system for promoting water body exchange is located at the back end of the flowing water aquaculture system, reducing The impact of relatively rapid water on aquaculture organisms is conducive to the collection of feces and residual bait produced by aquaculture itself, and to avoid the pollution of aquaculture to water bodies.

Background technique

With the continuous increase of pond breeding density, a large amount of feces and residual bait pollute the pond water body, and untreated farming sewage is discharged into rivers and lakes, becoming a source of pollution for very scarce water resources. Reducing non-point source pollution from aquaculture has become an important topic in front of the majority of aquatic science and technology workers. At present, my country is mainly through the construction and facility of the circulating aquaculture system, the introduction of water treatment technology, and the construction of an artificial wetland system to reduce the pollution of the tail water of the aquaculture.

This technical solution can partly solve the problems of concentrated running water high-density breeding and feces collection, reduce the dependence of aquaculture on the external water environment, reduce the damage of aquaculture to the environment, greatly reduce or even avoid the pollution of aquaculture water from the tail water of aquaculture, and realize feeding. The zero-emission of breeding can better guarantee the quality and safety of aquatic products, and at the same time improve the production and efficiency of farming. However, because the water-based aquaculture system is equipped with a power device at the front end, it is a forward-push flow-water aquaculture system, resulting in a relatively rapid and concentrated water flow that stimulates the aquaculture organisms in the aquaculture container, which has a great impact, especially the aquaculture organisms are frequently topped with water and scratches.
