Description

TECHNICAL FIELD

[0001] The utility model relates to crab device technical field, especially a pond crab device. BACKGROUND

[0002] In the crab breeding industry, parent grading boxes play an important role. Through the grading box, breeders can select large, healthy, and mature parent crabs for breeding. This ensures the quality of the offspring and improves overall breeding efficiency. Breeders may need to separate the male and female crabs for separate management. Grading boxes can help separate male and female crabs for more precise control of the breeding process. By placing parent crabs in a grading box, breeders can better control the breeding season and ensure that the crab larvae hatch at the best time, thereby improving survival rates.

[0003] The perimeter of the parent grading box is usually composed of a fence made of stainless steel, plastic, or other corrosion-resistant materials. The mesh size of the fence needs to be designed according to the species and size of the crabs being bred to ensure that the crabs cannot escape while allowing water exchange and observation by the breeder. The bottom of the parent grading box is usually made of a solid material to withstand the weight and movement of the crabs and possible maintenance operations. It can be a solid plate made of metal or plastic to prevent the crabs from digging into the bottom or to provide a stable standing surface. However, using a solid plate results in a large amount of sediment on the solid plate, while a meshed bottom facilitates water circulation and reduces sediment at the bottom, but cannot provide a stable standing surface for the crabs.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Examples, such as Figures 1 to 5 As shown, this utility model proposes a pond crab farming device, including a rectangular mesh fence 1 formed by overlapping each other. The mesh fence 1 is fixed in the pond and suspended inside the pond. Multiple floats 101 are fixedly installed on both sides of the mesh fence 1, with the floats 101 located in the middle of the mesh fence 1. The buoyancy of the floats allows the mesh fence 1 to float in the water. A certain gap is left between the bottom of the mesh fence 1 and the pond bottom 6. A walkway 7 for people to walk on is provided inside the pond, located above the mesh fence 1. The pond is located outside the mesh fence 1 and is used for planting aquatic plants.

[0025] Multiple underwater cameras 4 are installed around the mesh fence 1, with floats 401 fixed to each camera. The floats 401 suspend the underwater cameras 4 above the water level 5. Installing multiple underwater cameras 4 around the mesh fence 1 inside the pond is an effective monitoring and management method. The underwater cameras 4 are not directly connected to the mesh fence 1 and can be used to observe crab behavior, growth status, and monitor the environment of the parent grading tanks. This facilitates observation of crab activity patterns, mating behavior, and feeding habits. It also allows for regular checks of crab size and health, enabling timely adjustments to feeding and management measures, and monitoring of environmental factors such as water quality and light to ensure suitable aquaculture conditions. The underwater cameras 4 are connected to a data transmission cable, which needs to be long enough to connect to monitoring equipment on shore.

[0026] The underwater camera 4 allows for observation of the crabs' living habits and facilitates research and visits.

[0027] The embodiment further comprises a detachable bottom plate 2 installed at the bottom of the grid fence 1, the detachable bottom plate 2 comprises a mesh support 201 and a plurality of sealing plates 203 located below the mesh support 201, the sealing plates 203 fill the gaps on the mesh support 201.
