Pond water self-circulation system and method for prawn intensive culture pond

Abstract

The invention discloses a pond water self-circulation system and method for a prawn intensive culture pond. The system comprises a discharge pipe whereby the pond and the bottom center of a discharge well are communicated. A pond water self-circulation device is further disposed in the pond and comprises an inflation pump, a forked pipe, an air pipe and a floating soft foam plate; the lower end of the forked pipe which is vertically arranged is communicated with the discharge pipe; the upper end of the forked pipe is connected with the floating soft foam plate; the floating soft foam plate is provided with a through hole corresponding to an upper opening of the forked pipe; the inflation pump is mounted on the edge of the pond; one end of the air pipe is connected with an air outlet of the inflation pump; the other end of the air pipe penetrates the through hole and is disposed in the opening of the forked pipe; a lead weight and an air stone are fixed to the end of the air pipe; the inflation pump is started for inflating, and pond water can be circulated. The pond water self-circulation system and method has the advantages that upper and lower water in the prawn intensive culture pond is circulated by means of air stripping, the quality of the pond water is effectively kept stable, bottom pollution of the pond water is reduced, diseases are reduced, culture success rate is increased, and use value is high.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a pond water self-circulation system and method for intensive prawn cultivation ponds. Background technique [0002] Shrimp aquaculture is the pillar industry of marine aquaculture in my country, and the development of prawns is rapid, but diseases have become the most important restrictive factors of my country's prawn aquaculture industry. Since the outbreak of shrimp virus diseases in Fujian and eastern Guangdong in 1992, especially white spot syndrome (white spot syndrome, WSS), since it became popular in the whole country in 1993, WSS has become the most serious disease in the shrimp farming industry. During the three years from 1993 to 1995, the incidence of WSS in shrimp culture ponds in my country was over 90%, and the mortality rate of shrimp in affected shrimp ponds was close to 100%. However, the epidemiological and molecular biological detection techniques for shrimp virus...

AI Technical Summary

Problems solved by technology

However, since there is no buffering effect of the soil, and the waterwheel type aeration mode is adopted, the center of the mulch pond is likely to form a suspended sewage area, which is prone to diseases

Existing shrimp intensive ponds usually only rely on aerators to drive the surface water circulation of the pond, while the bottom water of the pond is difficult to participate in the circulation, and the water quality at the bottom of the pond is still very poor, and other methods are needed to purify the bottom water quality
