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

[0029] A water cycle sewage discharge method for indoor factory farming of Penaeus vannamei,

[0030] (1) Recoil sewage facilities

[0031] Breeding pond: The breeding workshop is covered with a plastic greenhouse or a glass-reinforced plastic tile greenhouse, with an opening area of ​​80m 2 -200m 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, the square shape is second, and the rectangular shape is relatively inferior.

[0032] Pool wall and pool bottom: Pool wall and pool bottom: The four corners of the vertical pool wall should not be at right angles. Cement should be used to make it into an arc shape, which not only prevents dead corners of residual dirt, but also avoids possible mechanical damage to the shrimp; The sewage outlet at the bottom of the pond is best located in the middle, and the slope of the four bottom corners and sides of the pond and the sewage outlet is 1%-2%; if the sewage o...

Abstract

An indoor factory farming Litopenaeus Vannamei water circulation pollution discharge method is provided; the connecting portion between the pool wall and pool bottom is in an arc shape; four bottom corners and four bottom edges of the pool bottom form 1-3% slope with pollution discharge ports, and the pool bottom and the pool wall are smooth; the pollution discharge ports are provided with isolation nets of different number; micropipe oxygenation is arranged on the pool bottom; when the culture pool is filled with water, four water wheels are placed on four corners of the culture pool opening water surface; before pollution discharge, the micropipe oxygenation is partially closed or fully closed, and the water wheels placed on pool opening water surface four corners are opened, so the water circulation can generate eddy currents so as to circulate the pool bottom deposits around the pollution discharge ports, thus discharging the pool bottom deposits outside the pool through the pollution discharge ports. The method is simple and convenient, can save labor and cost; pollution discharge effect can fully cover the pool without leaving blind points, thus thoroughly discharging deposits; basically no deposit can be re-circulated into the culture water in the pollution discharge process; the pollution discharge process is carried out step by step, no stress reaction can be caused on the Litopenaeus Vannamei, and no machinery damage can be caused.

Description

Technical field [0001] The invention relates to an aquaculture technology, in particular to a water cycle sewage discharge method for indoor factory farming of Penaeus vannamei. Background technique [0002] Penaeus vannamei belongs to the arthropod phylum, crustacea, Penaeus spp., with thin shell and fat, fresh and tender meat, and high meat yield. Penaeus vannamei is one of the three high-yield shrimp species in the world today. The high-quality Penaeus vannamei has a fast growth rate, It has the characteristics of wide temperature adaptability and strong disease resistance. It is suitable for artificial high-density farming. After desalination, it can be farmed in fresh water. At present, the sales of vannamei prawns in domestic and foreign markets are huge, and they are very popular with citizens. However, in recent years, with the adoption of various traditional farming models, the disease of vannamei shrimp has become more and more serious. The outbreak and prevalence of va...
