[0002] Sea cucumbers have important ecological functions such as cleaning the ocean substrate and biological agitation, and therefore play an important role in the marine ecosystem. my country's waters originally had abundant sea cucumber resources, but due to factors such as overfishing, wild sea cucumber resources are becoming increasingly depleted. In my country's South China Sea, sea cucumbers are extremely important for the material cycle of coral reef ecosystems, the periodic cycle of calcium carbonate, and the pH balance of seawater. Overfishing has also destroyed the ecosystem. Therefore, there is an urgent need to adopt artificial measures to restore sea cucumber resources. The current method of restoring sea cucumber resources mainly uses indoor artificial breeding of sea cucumber seedlings and re-proliferation and release.

A plurality of parallel crossbeams are arranged at intervals on the upper and lower surfaces of the square frame, and a plurality of attachment plates are fixed at intervals between the corresponding crossbeams on the upper and lower surfaces of the square frame. Fixed piles extending from the four vertical sides of the square frame are arranged at the four corners of the bottom surface of the square frame, four steel chains are fixed at the four corners of the top surface of the square frame, and are cross-linked at the ends.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] The utility model is further described below in conjunction with the accompanying drawings:

[0025] like Figure 1-Figure 5 As shown, the in-situ induced spawning device for sea cucumbers comprises a frame 1, wherein a plurality of horizontal bars 101 are inserted on the upper and lower surfaces of the frame 1, and an attachment plate 102 is fixedly connected between two corresponding horizontal bars 101, and the attachment plate 102 is made of polyethylene material, which is convenient for the sea cucumbers to climb and attach without being cut, and meshes 2 are bound to the six surfaces of the frame 1 by rolling belts, and the meshes 2 can ensure the continuous stimulation of seawater flow to the sea cucumbers, increase the amount of spawning females, and also allow the fertilized eggs to spread out quickly, and a fixed pile 3 is arranged at the bottom of the frame 1, and a spiral protrusion is welded on the outer wall of the fixed pile 3, so that the fixed pile 3 gradually descends while rotating;

[0026] A marking mechanism 4 is provided on the top of the frame 1. The marking mechanism 4 includes a steel wire rope 401 fixed on the top of the frame 1. A plastic rope 402 is connected to the intersection of the steel wire rope 401. A floating ball 403 is fixedly connected to the other end of the plastic rope 402. After the labor-inducing device is placed on the seabed, the floating ball 403 will float on the water surface, making it easy to quickly find the location of the labor-inducing device after labor-inducing.

[0027] An auxiliary mechanism 5 for driving the fixed pile 3 to rotate is provided on the top of the frame 1. The auxiliary mechanism 5 includes a rotating shaft 501 rotatably connected to the four corners of the top of the frame 1. A plurality of fan blades 502 are welded to the rotating shaft 501. The bottom of the rotating shaft 501 extends out of the frame 1 and is welded to the fixed pile 3. When the inducing device descends, the fan blades 502 will drive the rotating shaft 501 to rotate the fixed pile 3 under the action of the impact force of the water flow, thereby reducing the resistance between the fixed pile 3 and the seabed sand and gravel, prompting the fixed pile 3 to drill deeper into the seabed, and improving the fixing effect of the fixed pile 3.

[0028] Working principle: In the utility model, firstly, the wild ginseng is caught and transported to the base for temporary rearing for 1 day. On the afternoon of the day of induced labor, the seawater in the temporary rearing pool is drained, and the ginseng is dried in the shade for 1 hour in a conventional manner. Then, the mesh 2 on the side of the frame 1 is opened, and the shade-dried ginseng is evenly loaded into the in-situ induced labor device. The mesh 2 is quickly re-tied with a rolling belt, and the induced labor device is transported to the spawning site in the natural sea area by ship. The steel wire rope 401 and the plastic rope 402 are lifted, and the induced labor device is steadily placed on the seabed. When the induced labor device descends, the fan blade 502 will drive the rotating shaft 501 to drive the fixed pile 3 to rotate under the action of the impact force of the water flow, reduce the resistance between the fixed pile 3 and the seabed sand and gravel, and prompt the fixed pile 3 to drill deeper into the seabed, thereby improving the fixing effect of the fixed pile 3. Then, the ginseng is allowed to spawn naturally under the stimulation of the flowing water of natural seawater. After the ginseng is induced to spawn in situ for 3 days, the induced labor device is found through the float 403, the induced labor device is lifted, and the ginseng is returned to the sea, or taken back to the breeding base for continued breeding.

[0029] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
