Problems solved by technology

The current intensive recirculating aquaculture system mainly uses microfiltration to remove the former and biofiltration to remove the latter. This treatment method is used by the flow method, but it also shows limitations to the effectiveness of the system.
First of all, it occupies a certain proportion of the production environment; second, the efficiency of purification treatment fluctuates significantly; third, it needs to consume energy, equipment and manual maintenance and control

Abstract

The invention relates to the technical field of aquatic product aquaculture, in particular to an algal facies water prawn and shell connection circulating aquaculture system. The system comprises a shell aquaculture pond in the center, a prawn aquaculture pond in an annular structure surrounding the shell aquaculture pond, and an external water treatment device, wherein a water level of the shell aquaculture pond is higher than a water level of the prawn aquaculture pond; the shell aquaculture pond is provided with an overflow water outlet leading into the prawn aquaculture pond; the prawn aquaculture pond is internally provided with a drainage port; the drainage port is connected with the water treatment device by a pipeline; and the water treatment device is connected with a shell pond water distribution pipe arranged in the shell aquaculture pond by a pipeline. The system has the characteristics of low cost, low energy consumption, automatic purification, high yield and the like, can replace open intensive prawn aquaculture, totally-closed circulating water prawn aquaculture and shell pond aquaculture, and is widely applied to the industry of intensive aquaculture.

Description

technical field [0001] The invention relates to the technical field of aquatic product cultivation, and in particular to an algae phase water system shrimp and shell conjoined circulating aquaculture system. Background technique [0002] At present, most of the pond culture methods of seawater prawns and shellfish are open. In the process of open aquaculture, the residual bait, feces and microorganisms bred by exogenous nutrients are directly discharged through the behavior of changing water, and a large number of inorganic and organic nutrients such as ammonia nitrogen, phosphate, dissolved organic carbon and organic particles It directly enters the environment in the exchange of water bodies, which will cause the deterioration of the environment of the entire aquaculture water area, and then lead to a series of major problems that limit the sustainable development of aquaculture, such as water pollution, disease breeding, hygiene and safety of aquatic products. [0003] P...
