Prawn aquaculture pond

Abstract

The invention relates to the technical field of aquaculture, in particular to a prawn aquaculture pond. The prawn aquaculture pond comprises an aquaculture pond and a sedimentation tank, an inclined sewage collection plate and a collection tank are arranged at the bottom of the aquaculture pond, and a water pumping pipe is arranged at the horizontal lowest position of the collection tank. More than two conical sedimentation plates are peripherally connected to the horizontal section of the side wall of the sedimentation tank, a shell is provided with a cyclic water outlet above the uppermost sedimentation plates in the shell, and the cyclic water outlet is connected with the aquaculture pond through a pipeline. The center of the bottom wall is provided with a sewage outlet which is connected with a sewage outlet pipeline. The prawn aquaculture pond has advantages that by the sedimentation tank for cyclic purification of water in the aquaculture pond, cyclic treatment of aquaculture wastewater is completed so as to realize environment friendliness in aquaculture, and aquaculture yield can be increased; by an aquaculture system, water replacement amount is greatly decreased, water source and electric energy are saved, and accordingly aquaculture cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a prawn culture pond. Background technique [0002] Industrial shrimp farming is to use modern industrial means to control the ecological environment in the pond, create an optimal living and growth condition for prawns, promote the smooth growth of prawns, and improve the yield and quality per unit area under high-density intensive stocking conditions , and strive for higher economic benefits. Specifically, in the indoor cement pool or plastic pool with thermal insulation and light control, the water temperature is controlled at the optimum temperature for the cultured organisms through solar energy or other thermal energy; The breathing needs of the breeding objects can improve the water quality conditions in the pool; through appropriate water changes, harmful substances in the water can be removed, and beneficial substances can be supplied and supplemented to maintain go...

AI Technical Summary

Problems solved by technology

However, the existing shrimp ponds take a long time to change water, less water changes, the water quality in the shrimp ponds is poor, and the survival rate of prawns is low. If new water is frequently injected, or the amount of water exchanged increases, the water temperature in the pond will change significantly. Especially in the winter season, the survival rate of prawns is reduced, which reduces the production of prawns, resulting in low enthusiasm for shrimp farming, and the slow development of shrimp farming cannot meet the consumer demand of the market.
