Description

Technical Field

[0001] The utility model relates to the technical field of marine aquaculture, in particular to a roughing device for polyculture of rough sea cucumber seedlings in an outdoor pond. Background Art

[0002] The rough sea cucumber belongs to the genus Holothuroidea of ​​the family Holothuroidae. It is commonly known as sand cucumber and white ginseng. It generally lives on the edge of reefs and on sandy bottoms with fast tides and abundant seaweed.

[0003] Currently, indoor breeding technology for rough sea cucumbers has matured. Reports have also been published on the use of indoor cement tanks for the cultivation of small-sized juvenile sea cucumbers. Some researchers have also successfully experimented with larger sea cucumber seedlings in mudflat enclosures. However, research on outdoor coarsening, pond culture, and outdoor polyculture is limited. Indoor coarsening often involves high densities, and improper feeding can easily deteriorate water quality, leading to disease and death of sea cucumber seedlings, necessitating frequent bottom cleaning and pond emptying. Compared to indoor coarsening in cement tanks, outdoor coarsening offers advantages: less labor; full utilization of sunlight promotes the growth of benthic diatoms, allowing sea cucumber seedlings to consume a richer diet and obtain sufficient and diverse nutrition in a natural outdoor environment; and the large water volume of outdoor ponds offers a certain degree of self-purification, with a rich bacterial flora and a stable ecological environment, making it easier for sea cucumber seedlings to maintain health and reduce disease. Disadvantages: Small sea cucumber seedlings are easily preyed on by larger aquatic animals in natural environments; and sea cucumber seedlings prefer to avoid light, requiring shelter or burrowing into the sand.

[0004] Therefore, providing a device or equipment that can enable small-sized ginseng seedlings to play their advantages and avoid their disadvantages during the thickening stage is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] The present invention aims to solve at least one of the above-mentioned technical problems in the prior art to a certain extent. It provides a pond thickening device for small-sized sea cucumber seedlings, which protects the small-sized sea cucumber seedlings from predators while allowing them to obtain abundant food in the ecological environment of a large water body, thereby increasing their growth rate and ensuring their healthy development.

[0006] To this end, one object of the present invention is to provide a roughing device for polyculture of rough sea cucumber seedlings in outdoor ponds, comprising a frame, a cage and a flexible mesh;

[0007] The frame is a rectangular parallelepiped structure composed of hollow tubes; the cage is fixed inside the frame, and the size of the cage matches the size of the frame;

[0008] There are a plurality of flexible mesh sheets, and the plurality of flexible mesh sheets are irregularly arranged inside the mesh box;

[0009] The area of ​​the flexible mesh is equal to or greater than the area of ​​any cross section of the cage;

[0010] The frame is provided with a plurality of limiting ropes, and any hollow tube of the frame is provided with at least one limiting rope;

[0011] The frame is provided with a plurality of counterweight blocks, and at least one counterweight block is provided at any top corner of the frame.

[0012] Furthermore, the specifications of the frame and the cage are both 1m×1m×1m.

[0013] Furthermore, the area of ​​the flexible mesh is 1-2m 2 .

[0014] Furthermore, the frame is composed of PVC pipes, and the joints thereof are connected by PVC elbows or PVC tees.

[0015] Furthermore, the mesh box and the flexible mesh are both made of nylon.

[0016] The PVC pipe makes the entire frame have a certain buoyancy in the water, and the entire roughing device can be suspended in the upper part of the water layer to obtain sufficient light and promote the growth of benthic diatoms. In order to prevent the frame from floating too high, counterweights of different weights can be set to control the suspension height of the entire roughing device.

[0017] Furthermore, the net box is provided with a plurality of holes, the aperture of which ranges from the aperture of a 20-80 mesh screen;

[0018] The flexible mesh is provided with a plurality of holes, the aperture of which ranges from the aperture of an 80-250 mesh screen.

[0019] Furthermore, it also includes at least one zipper switch;

[0020] The zipper switch is arranged in the middle of any one side of the net box, and at most one zipper switch is arranged on any one side of the net box.

[0021] Furthermore, the zipper length of the zipper switch is 60-100 cm, and the zipper is made entirely of plastic.

[0022] Furthermore, the other end of the limiting rope on the frame is connected to the bank of the pond, and only one limiting rope on the hollow tube is connected to the bank of the pond.

[0023] In the scheme of the present invention, the flexible mesh can be folded in disorder and then placed in the cage when in use. It will spread out under the buoyancy of water, increase the activity space of the ginseng seedlings, provide shielding for the ginseng seedlings, and build a partial weak light environment. The marking device of the present invention needs to be completely immersed in water when in use, and can be turned over regularly so that all sides of the cage can obtain light, promote the growth of benthic diatoms, and provide more food for the ginseng seedlings. The frame provided by the present invention mainly plays a supporting role, so that the breeding space in the cage can be expanded, and at the same time, it provides convenience for turning the cage during use; the cage can isolate enemies, protect small-sized ginseng seedlings from harm, and greatly improve the survival rate; the mesh is placed in the cage to increase the activity space of the ginseng seedlings, increase the growth area of ​​benthic algae, and provide more food for the ginseng seedlings.

[0024] The beneficial effects of the present invention are as follows: the thickening equipment provided by the present invention is easy to move and flip, has a simple structure, is easy to make, and can be recycled. The thickening equipment of the present invention can be used in large water bodies, and the water quality of large water bodies is stable, which can reduce the incidence of sea cucumber seedlings. The thickening equipment of the present invention can not only use outdoor light to promote the growth of benthic algae, provide more abundant food for sea cucumbers, and increase the growth rate, but also use the built-in mesh to construct a low-light area and build a habitat suitable for sea cucumber seedlings. At the same time, the thickening equipment of the present invention enables sea cucumber seedlings to be co-cultured with other aquatic products (such as Babylonia square-spotted, Starworm, etc.), and the body length of rough sea cucumbers can grow from 0.1cm to 0.3cm to 3cm in the thickening equipment, and the survival rate of rough sea cucumber seedlings is guaranteed.
