Description

Technical Field

[0001] The utility model particularly relates to a high-yield Australian freshwater lobster breeding device. Background Art

[0002] Australian freshwater lobsters, native to Oceania, are a type of large freshwater shrimp introduced from Australia in recent years, including two species: red-clawed crayfish and toothed crayfish. For example, red-clawed crayfish have a faster growth rate, can reproduce and hatch naturally in fresh water, have a higher survival rate and stronger disease resistance; existing red-clawed crayfish are usually cultured in ponds, and the bottom and side walls of the ponds become the activity areas of red-clawed crayfish. However, due to the excessive growth rate of red-clawed crayfish, in order to ensure the quality of red-clawed crayfish culture, only a small number of them can be cultured in this activity area. If a high yield of red-clawed crayfish is to be obtained, the volume of the pond can only be expanded or the number of ponds can be increased, thereby increasing the cost of culture and management.

[0021] A high-yield Australian freshwater lobster farming device, referring to Figure 1-Figure 2 , including a breeding warehouse 2 for being placed in a pond 1, the breeding warehouse 2 is provided with an opening 3, the breeding warehouse 2 is provided with an active channel 4 connected to the pond 1, an eco-friendly grid is placed in the active channel 4, the eco-friendly grid is a honeycomb structure formed by a plurality of connecting members 51 connected to each other, and each connecting member 51 is provided with a crawling channel 52.

[0022] Furthermore, the connecting member 51 is arranged along the length direction of the breeding warehouse 2 and both ends of the crawling channel 52 are respectively located at the opening 3 of the breeding warehouse 2.

[0023] Furthermore, the longitudinal cross-section of the crawling channel 52 is a hexagonal structure.

[0024] Furthermore, the breeding warehouse 2 includes a first fixing frame 21 and a second fixing frame 22 connected to the first fixing frame 21 , and meshes 23 are provided on both the first fixing frame 21 and the second fixing frame 22 .

[0025] Furthermore, the longitudinal cross-section of the breeding warehouse 2 is a trapezoidal structure.

[0026] Furthermore, the mesh cloth 23 is made of nylon.

[0027] The working principle of the utility model is:

[0028] Taking red-clawed crayfish as an example, the red-clawed crayfish is put into the pond 1. Since the breeding warehouse 2 is placed in the pond 1 (the breeding warehouse can be fixed to the bottom of the pond by fasteners, or there is no connection between the breeding warehouse and the bottom of the pond), an active channel 4 is opened in the breeding warehouse 2, and an eco-simulation grid is placed in the active channel 4. As an embodiment 1, the eco-simulation grid can be a honeycomb structure formed by connecting multiple connectors 51, and each connector 51 is provided with a crawling channel 52; so the red-clawed crayfish put into the pond 1 can crawl into the active channel 4, crawl into the crawling channel 52 opened on the connector 51, and can also crawl to the top of the breeding warehouse 2. Therefore, the breeding device of the present application increases the activity area of ​​the red-clawed crayfish on the basis of the original breeding area of ​​the pond 1, and can increase the breeding amount and improve the yield while ensuring the breeding quality of the red-clawed crayfish; in addition, it is not necessary to increase the number of ponds 1 and expand the volume of the pond 1 to achieve high-yield output value, which reduces the breeding cost and is conducive to promotion and application.

[0029] On the basis of the above technical solution, in order to increase the activity area of ​​the red-clawed crayfish, the longitudinal cross-section of the crawling channel 52 is preferably set to a hexagon. The hexagon can increase the contact area between the crawling channel 52 and the red-clawed crayfish, and can also increase the fluidity of the air, making the red-clawed crayfish more adaptable to growth.

[0030] On the basis of the above technical solution, in order to enable the red-clawed crayfish to crawl stably on the surface of the breeding chamber 2, the breeding chamber 2 can be configured as a first fixed frame 21 and a second fixed frame 22, and meshes 23 are hung on the first fixed frame 21 and the second fixed frame 22 respectively. The setting of the meshes 23 can enable the red-clawed crayfish to crawl stably on the breeding chamber 2. As embodiment 1, the meshes 23 can be made of nylon.

[0031] On the basis of the above technical solution, regarding the setting of the eco-friendly grid, 6-8 layers of connectors 51 can be arranged in the vertical direction, and the number of connectors 51 in the horizontal direction can be increased or decreased according to the distance between the lower end of the first fixing frame 21 and the lower end of the second fixing frame 22.

[0032] Although the utility model is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications can be made to the utility model without departing from the principle and spirit of the utility model defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the utility model, but the scope of protection is limited by the content of the claims.
