[0019] In order to make the present application clearer, the present application will be further described in conjunction with the drawings.

[0020] In the following description, the example details are given in order to provide a more in-depth understanding of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. It should be understood that the described specific embodiments are only used to explain the present application, and are not used to limit the present application.

[0021] It should be understood that when the terms "comprise" and / or "include" are used in the specification, it indicates the presence of the described features, whole, steps, operations, elements or components, but does not exclude the presence or addition of one or more other features, whole, steps, operations, elements, components or combinations thereof.

[0022] Please refer to Figures 1-5 The present application is a kind of artificial breeding nest structure for small crayfish breeding in sandy soil in northwest arid area, comprising a plurality of breeding devices stacked to form the artificial breeding nest, the breeding device comprises breeding pipe 1 and breeding net 2, the breeding pipe 1 is provided with opening for small crayfish to enter and exit at both ends, and is provided with strip-shaped through hole 4 and a plurality of flow-through holes 3 in the length direction of breeding pipe 1;At least two breeding pipes 1 are arranged oppositely, the breeding net 2 is respectively threaded through the strip-shaped through hole 4 of two breeding pipes 1 at both ends, and the breeding net 2 and the breeding pipe 1 are fixed by PP strap;The splicing between the breeding devices of the present application is not limited to longitudinal stacking, but also can be expanded in horizontal direction, two breeding pipes 1 can be fixed and connected by threading the flow-through holes 3 on two adjacent breeding pipes 1 with PP strap, which can better adapt to the bottom topography and increase the production rate of small crayfish breeding.

[0023] In this embodiment, since there are more sandy soil in the water body in the northwest arid region, and the small crayfish needs a good water environment to breed in the breeding pipe 1, the utility model sets the flow hole 3 on the breeding pipe 1, and the flow hole 3 is arranged at intervals of 5 cm along the length direction of the breeding pipe 1, and the diameter of the flow hole 3 is 5 mm. The water in the pipe can flow normally through the flow hole 3 with a diameter of 5 mm. The flow hole with too large diameter can cause foreign matters in the water to enter the breeding pipe, and the flow hole with too small diameter can affect the flow of the water. Therefore, the diameter of 5 mm is selected to affect the small crayfish in the pipe and ensure the flow of the water, so that the water in the breeding pipe 1 is continuously updated and flows, the dissolved oxygen content in the pipe is improved, and the excrement or foreign matters discharged by the small crayfish are taken away by the flowing water, thereby creating a more suitable growth environment for the small crayfish.

[0024] In this embodiment, the breeding net 2 is a non-toxic and harmless laminated net piece woven by a machine. The width of the net piece is 30 mm, the length is 100 mm, and the mesh diameter is 0.05 mm. Since the water quality environment in the northwest region is poor, most of the sand is fine, and the diameter of the sand is generally 1 mm to 0.05 mm. The mesh size of the ordinary breeding net 2 is larger than that of the sand. In the flowing water, the sand can pass through the mesh of the breeding net 2 and slowly accumulate and cover the shrimp eggs dropped by the small crayfish, so that the shrimp eggs cannot be hatched smoothly, thereby causing certain economic losses to the breeders. Therefore, the mesh diameter of the breeding net 2 is configured as 0.05 mm to isolate most of the sand from passing through, so as to ensure that the shrimp eggs can be hatched normally.

[0025] The breeding net 2 and the breeding pipe 1 are bound and fixed by the PP binding belt. The PP binding belt can connect and fix different breeding devices and adjust the distance interval between the different breeding devices, thereby ensuring the stability and consistency of the breeding nest.

[0026] In this embodiment, in order to make the environment of the breeding device more suitable for the small crayfish breeding, the breeding device is provided with the baffle 5 on both sides. The baffle 5 can prevent the small crayfish eggs from escaping, and can also increase the light-proof property and the heat preservation property of the breeding device, so that the small crayfish can stably inhabit in the breeding device.

[0027] The advantage of the utility model lies in that:

[0028] 1. The breeding device can be spliced in the longitudinal or transverse direction, and is suitable for the water bottom topography.

[0029] 2. The breeding device adopts the light-proof PVC pipe material, has good light-proof property, and is provided with the flow hole on the breeding pipe to increase the flow property of the breeding device, so that the dissolved oxygen content of the water in the pipe can meet the breathing and breeding of the small crayfish.

[0030] 3. The utility model discloses a breeding net can collect crayfish's roe, prevent crayfish from escaping at the same time.

[0031] 4. The utility model discloses increase the survival rate and the breeding speed of crayfish's young shrimp, further improve the production economic benefits of crayfish in the northwest arid region.

[0032] The above disclosed is only a few specific embodiments of the utility model, but the utility model is not limited to this, any change of the person skilled in the art can think of falling into the protection scope of the utility model.
