Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to an assembleable device for laying eggs, hatching and breeding snakeheads. Background Art

[0002] The incubation of Channa argus is generally semi-artificial. After induced spawning, the male and female fish are paired one-to-one and placed in a cage to spawn naturally. Traditional spawning and hatching cages are mostly made of wood, iron, and steel. In recent years, foam boxes are mostly used for the breeding of Channa argus, which are not only costly but also not durable, and cannot be disassembled at will, so they cannot be flexibly applied to spawning and hatching ponds of different sizes. In addition, they occupy a large area when idle, wasting space resources. In order to solve the above technical problems, those skilled in the art have made the following efforts. For example, a Chinese patent, the authorization announcement number is CN206576068U, which discloses a cage structure for freshwater fish farming, wherein a buoy is fixed to the outside of the rectangular frame by a fixing ring, a bolting ring and a partition fixing device are welded on the inner side wall of the rectangular frame, a nylon rope is bolted to the bolting ring, and the nylon rope is sewn to the edge of the bag mouth of the nylon mesh bag. However, the floating fixing method adopted in the above scheme is not suitable for the spawning, hatching and breeding process of Channa argus, and this cage structure is not conducive to expansion due to the interference of the buoy at the top. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide an assembleable device for laying eggs, hatching and breeding snakeheads.

[0004] The technical solution adopted by the utility model is as follows:

[0005] An assemblable spawning, hatching and breeding device for snakehead fish comprises a plurality of breeding cage units, wherein:

[0006] Each aquaculture cage unit is in the shape of a cuboid / cube, including a bottom frame, a cage, a top cover and a zipper; the bottom frame is a hollow tubular structure filled with sand and gravel for counterweight, the cage is a tubular structure sewn with 40-60 mesh mesh, zippers are arranged around the top edge of the cage, and the top cover is fixed on the top of the cage by the zipper;

[0007] Adjacent aquaculture cage units are assembled by zippers, and four end points of the assembled aquaculture cage units are provided with clamping joints, through which nylon ropes pass to suspend and fix the aquaculture cage units.

[0008] This technical solution modularizes the aquaculture cage units by improving their structure, making the aquaculture process more flexible and efficient. Specifically, the aquaculture cage units are used as basic modules, and each unit has an independent bottom frame, cage, top cover and zipper, which is easy to manufacture, transport and assemble. The bottom frame adopts a hollow tubular structure and is filled with sand and gravel to increase the weight and stability of the device and prevent the influence of external forces such as wind and waves on the aquaculture environment; 40-60 mesh mesh is used to sew the cage to ensure that the eggs and fry of black snakehead can be safely hatched and grown, while preventing small predators from entering; the zipper allows the top cover and the cage to be opened and closed quickly, which is easy to manage and maintain; the card joints and nylon ropes allow the aquaculture cage units to be easily assembled and hung.

[0009] In addition, the above-mentioned assemblable snakehead spawning, hatching and breeding device according to the utility model may also have the following additional technical features:

[0010] According to an embodiment of the utility model, the mesh of the net cage has a mesh number of 40-60 during spawning and hatching, and is replaced according to the size of the fry during breeding.

[0011] The technical solution adjusts the mesh size of the net cage to meet the needs of the black snakehead at different growth stages, and ensures that the black snakehead grows in a suitable environment during the spawning, hatching and breeding stages, thereby improving the breeding efficiency.

[0012] According to an embodiment of the utility model, the bottom frame is composed of four PVC pipes, and the PVC pipes are filled with sand and gravel to avoid gaps, so as to prevent the bottom frame from floating up and the cage from drifting with the water flow.

[0013] This technical solution adopts PVC pipe as the structural material of the bottom frame and fills it with sand and gravel to ensure that the cage can be stably sunk into the water and prevent the cage from drifting with the water flow, thereby providing a stable spawning and hatching environment for the black snakehead.

[0014] According to an embodiment of the utility model, the side length of the PVC tube of the net box is consistent with the side length of the bottom of the net box, and when the net box is placed, the mesh cloth is stretched out to form a rectangular bottom frame.

[0015] The PVC pipe side length of the bottom frame described in the technical solution is consistent with the side length of the bottom of the net box, and is directly placed at the bottom of the net box, which not only simplifies the installation process but also enhances the stability and durability of the net box.

[0016] According to an embodiment of the utility model, the clamping joints at the four end points of the aquaculture cage unit are metal rings.

[0017] The technical solution increases the durability and stability of the clamping joints by using metal rings as clamping joints at the end points of the aquaculture cage units, making the aquaculture cage units more secure and reliable when suspended and fixed.

[0018] According to an embodiment of the utility model, the aquaculture cage unit is assembled along at least one direction of four sides by means of a zipper.

[0019] The aquaculture cage units of the technical solution are assembled along at least one direction of the four sides by zippers, providing multiple assembly methods, such as three to four can be arranged in a straight line as a group, or four can be arranged in a well shape as a group, etc. Multiple assembly methods enable the device to be flexibly configured according to different aquaculture needs and site conditions.
