Circulating water device for prawn breeding

Abstract

The invention discloses a circulating water device for prawn breeding. The device includes a prawn culture pond, a waterproof layer, an ozone outflow opening, an oxygen generator, a circulating oxygen-increasing pipe, a culture-pond middle plate, and a sludge outflow opening. The circulating oxygen-increasing pipe is installed at the upper part of an oxygen-increasing disc, the culture-pond middleplate is installed at the upper part of the circulating oxygen-increasing pipe, the sludge outflow opening is installed at the upper part of the culture-pond middle plate, an ozone generator is installed at the lower part of the sludge outflow opening, a separation plate is installed at the lower part of the ozone generator, an aeration tank is installed at the lower part of the separation plate,an aeration disc is installed at the lower part of the aeration tank, and a separation-plate opening valve is installed at the lower part of the aeration disc. The beneficial effect is that the use of an air flow to complete water circulation in the culture pond can effectively increase the survival rate of prawns and ensure the economic benefit of the farmer.

Description

technical field [0001] The invention relates to the field of prawn farming equipment, in particular to a circulating water device for prawn farming. Background technique [0002] Penaeus vannamei belongs to Arthropoda, Crustacea, Penaeus genus, thin shell and fat body, fresh and tender meat, high meat yield; Penaeus vannamei is one of the three high-yielding shrimp species in the world today, high-quality Penaeus vannamei has fast growth, Wide temperature adaptability, strong disease resistance, etc., are suitable for artificial high-density breeding, and can be cultured in fresh water after desalination. At present, the sales volume of Penaeus vannamei is huge in domestic and foreign markets, and it is very popular among the public. However, in recent years, with various traditional farming models, the diseases of Penaeus vannamei have become more and more serious. The outbreak and prevalence of various shrimp diseases, mainly stealing disease and white spot disease, have b...

Problems solved by technology

[0003] However, due to the high density of industrial farming of Penaeus vannamei, there are many disadvantages in the traditional artificial siphon sewage discharge, a large amount of feces, residual bait, metabolites, etc. sink to the bottom of the pond, and it is easy to cause the death of the shrimp during the water circulation
