To the problem that above-mentioned prior art exists, the utility model provides a pond three-layer protection system is bred to high-efficient river crab seed. Through the construction of the three-layer protection system, the pond ridge collapse and escape caused by the digging of the crab seedlings are avoided, the recapture rate is improved, the system is also convenient to maintain, and workers can easily patrol and catch the pond.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a three-layer protection system of a high-efficiency river crab fry culture pond sequentially comprises a hard cement plate slope protection outer layer, a thick PE film escape-proof middle layer and a bolting silk net escape-proof inner layer from outside to inside, wherein the hard cement plate slope protection outer layer extends from a pond ridge to the inside of the pond. Hard cement board slopes are laid at the edges of the pond ridges to prevent crab seedlings from escaping and digging holes; the lower edge of the slope of the cement board is covered by soil, and a mesh layer for skid resistance is laid on the surface of the slope; the thick PE film anti-escape middle layer is vertically erected on the mesh layer, the bolting silk net anti-escape filtering inner layer is vertically erected in the pond, and in order to ensure that the thick PE film anti-escape middle layer and the bolting silk net anti-escape filtering inner layer are vertically fixed, the system further comprises a reinforcing device.

Furthermore, the reinforcing device comprises a steel pipe which is vertically erected and a steel wire rope for transverse stretching and fixing.

Preferably, the slope of the outer layer of the cement board slope protection is 1: 2, the culture pond can be adjusted to be fine according to the actual situation of the culture pond.

The bolting silk net is preferably 80 meshes, is designed by considering the size of the river crab seedling, and can be adjusted according to the variety of the culture product.

The slope edge of the cement board is covered by soil, and the surface of the cement board is paved with an anti-slip mesh layer to prevent weeds from growing and facilitate the walking and nursing of workers. A shallow water channel with the width of about 50 centimeters is reserved between the thick PE film escape-proof middle layer and the bolting silk net escape-proof inner layer so as to enlarge the moving range of the inner layer for escaping the crab seedlings and ensure the supply of water source and bait.

Furthermore, the thick PE film anti-escape middle layer is composed of thickened PE white plastic cloth, and the net cloth layer is composed of double-layer green net sheets.

The beneficial effects of the technical scheme are mainly embodied in the following aspects:

1. through setting up three-layer protection system, can prevent that the crab seedling of fast maturity from digging into a hole and flee away and the seedling from the bed mud to prevent enemy such as water mouse, frog from invading and swallowing the seedling, reduce the crab seedling and dig into in winter, be convenient for concentrate and catch, increase the overall promotion rate of recapture rate about 10%, promoted the economic benefits of breed.

2. The three-layer protection system can also reduce the loss of bait, enhances the feeding efficiency of the young seedlings, and leaves a shallow water channel between the thick PE film escape-proof middle layer and the bolting silk net escape-proof inner layer, thereby providing a larger range of activity for escaping the crab seedlings from the inner layer and ensuring the supply of water sources and bait.

3. The outer layer of the slope protection of the hard cement board avoids the phenomena of water leakage of the culture pond and collapse of the pond ridge caused by digging holes by crab seedlings. The screen cloth layer has the antiskid effect, does benefit to the tricycle and goes and personnel walk and patrol the pond, patrols the pond, sleet weather work provides convenience for raiser night. The slope surface protective layer material is durable in use and long in service time, avoids the growth of weeds on the slope surface of the culture pond, does not need to use a herbicide, increases guarantee for food safety, and reduces labor and saves herbicide expenditure.

4. The utility model discloses an installation structure is simple firm and clean and tidy beautiful, thoroughly changes the dirty and disorderly face of traditional breed pond, the cleanness of being convenient for is arranged. Still have economical and practical's advantage, cost is with low costs, long service life, the bank protection is effectual, bank protection easy operation, and the practicality is strong, can promote on a large scale.

5. The thick PE white plastic film selected for use has the characteristic of high wear resistance, the double-layer green net sheet can better protect the PE white plastic cloth and has stronger anti-skidding function, the thick PE white plastic cloth and the double-layer green net sheet can be integrated with the surrounding environment, and river crabs can not be frightened while the appearance is attractive.
