Problems solved by technology

[0004] However, due to the high density of industrial cultured Penaeus vannamei, there are many disadvantages in the sewage discharge through the traditional artificial siphon method. A large amount of feces, residual bait, metabolites, etc. sink to the bottom of the pond. It is also a carrier for the mass reproduction of pathogenic microorganisms

Embodiment Construction

[0032] A recoil blowdown method for indoor factory culture of Penaeus vannamei,

[0033] (1) Recoil sewage facilities

[0034] Breeding pond: The breeding workshop usually adopts a plastic greenhouse or a glass steel tile greenhouse to seal the roof, and the area of ​​the breeding pond mouth is generally 5m 2 -30m 2 , the water depth is 1.2m-1.5m, the pool mouth is too large or too small, the effect is not good, the pool mouth is round the best, followed by the square shape, and the rectangular shape is relatively poor.

[0035] Pool wall and pool bottom: Pool wall and pool bottom: The four corners of the vertical pool wall should not be at right angles, and should be made into arcs with cement, which not only prevents dead corners of residual dirt, but also avoids possible mechanical damage to prawns; The sewage outlet at the bottom of the pool is preferably located in the middle, and the slope of the four bottom corners and four bottom edges of the pool bottom and the sewa...

Abstract

An indoor Litopenaeus Vannamei factory cultivation back flushing pollution discharge method comprises the following steps: making an arc shape between pool walls and the pool bottom, arranging the slope between pool bottom four corners and four bottom edges and drain exits as 1%-3%, and keeping the pool bottom and pool walls to be smooth; setting isolation nets of different numbers on the drain exits, and placing and fixing micro tubes, nano tubes or exhaust stone bonds on the pool bottom four corners and bottom edges; placing drifting exhaust stones in the drain exits; scientifically designing pool opening slope and discharge micro tubes, exhaust stones or nano tubes, determining standard aeration quantity, and using water decomposition principle and active force and reaction force principle to push water for pollution discharge. The method is simple and convenient, saves labor and cost, is fully coverable in discharge effect, leaves no blank area in the pool, and thorough and clean in pollution discharge; basically no deposit can reappear in the culture water in pollution discharge, and the discharge process is carried out step by step with no radical operations, thus causing no stress reaction on the Litopenaeus Vannamei, and causing no machinery damages.

Description

technical field [0001] The invention relates to an aquaculture technology, in particular to a recoil type sewage discharge method for indoor factory culture of Penaeus vannamei. 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 a...
