Horizontal flow shellfish culture system by utilizing shrimp culture tail water

Abstract

The invention discloses a horizontal flow shellfish culture system by utilizing shrimp culture tail water. The system comprises a fish purification pond with fishes cultivated and a horizontal flow shellfish culture pond with shellfishes cultivated which are communicated sequentially, wherein a water inlet passage for introducing shrimp culture tail water is arranged on the fish purification pond;and a first valve group is arranged at the part where the horizontal flow shellfish culture pond and the fish purification pond are communicated. As the fish purification pond for introducing the shrimp culture tail water and the horizontal flow shellfish culture pond communicated with the fish purification pond are built, the fishes in the fish purification pond can remove suspended substances in the culture tail water, the nutrient-enriched tail water after one-time purification flows into the shellfish culture pond again, the tail water which finally flows out can meet the standards of pollution-free discharge or recycling, and by cultivating the shellfishes in the horizontal flow shellfish culture pond, considerable economic benefits can be acquired.

Description

technical field [0001] The invention relates to the technical field of aquaculture systems, in particular to a horizontal flow shellfish culture system utilizing tail water from prawn culture. Background technique [0002] Shrimp factory farming has the characteristics of short time, convenient management and high yield, and has a large profit margin. It has developed rapidly in recent years. In order to maximize the benefits, high-density, high-feeding farming methods are usually adopted in industrialized shrimp farming. This model has brought a series of problems, such as the generation of sewage enriched in nutrients such as nitrogen and phosphorus, which not only causes the breeding environment In addition, the sewage discharged into the coastal waters along with surface runoff has also led to the deterioration of the water quality in the local sea area and the destruction of the ecological balance. [0003] But on the other hand, the tail water of industrialized shrimp...
