As shown in fig. 1 to 5, the high-density beach green crab culture device comprises a culture fish raft 1 arranged in a beach area, netting 2 for embedding beaches are arranged around the culture fish raft 1, a plurality of culture areas 3 are arranged inside the culture fish raft 1, at least one crab nest 4 is arranged in each culture area 3, and one green crab is arranged in each crab nest 4. The net clothes embedded into the mud flat are arranged around the cultured fish steaks, so that the escape of the blue crabs can be prevented.

In this embodiment, breed fish raft 1 and include fish raft frame 5 of rectangle form, the side all around of fish raft frame 5 all is connected with the netting 2, and fish raft frame 5's inside is fixed with violently indulges crisscross horizontal bracing piece 6 and longitudinal support pole 7, and fish raft frame 5's inside separates into a plurality of breed districts 3 via violently indulging bracing piece 6 and longitudinal support pole 7, and adjacent breed district each other does not communicate. Preferably, the plurality of culture areas are distributed in a matrix.

In this embodiment, the side edges around the fish raft frame 5 and the transverse support rods are provided with floating balls 8.

In this embodiment, all be connected with spud pile rope 9 in the top angle department all around of breeding fish raft 1, the spud pile rope is used for being connected with the peripheral fixed building of breeding the fish raft to it is fixed to breed the fish raft entirely.

In this embodiment, the crab nest 4 includes a hollow and cuboid crab nest body 10, the left end of the crab nest body 10 is provided with a crab inlet bundling opening 11, the right end of the crab nest body is provided with a crab outlet bundling opening 12, the crab inlet bundling opening 11 and the crab outlet bundling opening 12 are both in a cone shape with a large left end opening diameter and a small right end opening diameter, and by adopting the cone-shaped structure, when green crabs enter the crab nest body from the crab inlet bundling opening, green crabs cannot escape from the crab inlet bundling opening, and external green crabs cannot enter the crab nest body from the crab outlet bundling opening. By adopting the structure of the closing port, the closing device is convenient to close a flat linear port and is convenient to open and close. It should be noted that the crab inlet and crab outlet are both of the same structure as the closing openings at the two ends of the existing underground cage, and are of a net structure, and the structure thereof is not repeated here.

In the embodiment, a crab nest inlet 13 for installing a crab incoming port 11 is formed in the upper end of the left side face of the crab nest body 10, a support plate 14 for supporting the crab incoming port 11 is arranged at the lower end of the crab nest inlet 13, a sliding plate 15 for facilitating green crabs to slide downwards is arranged on the right side of the support plate 14, the sliding plate 15 is fixed on the side wall of the crab nest body 10, the sliding plate 15 is in an inclined shape with a high left end and a low right end, a support frame 16 and a seesaw 17 are arranged below the sliding plate 15, the upper end of the support frame 16 is hinged to the left side of the middle of the seesaw 17 through a hinge shaft which is longitudinally arranged, and the seesaw can swing up and down around the hinge shaft; the upper part of the left end of the seesaw 17 is vertically provided with a blocking plate 18, the upper end of the blocking plate 18 extends into a gap between the support plate 14 and the sliding plate 15, the bottom of the blocking plate 18 is provided with a support roller 19, the support roller 19 is in contact with the top surface of the left end of the seesaw 17, when green crabs slide to the right end of the seesaw 17 from the sliding plate 15, the seesaw 17 pushes the blocking plate 18 to vertically move upwards and shield the crab inlet bundling port 11, so that other green crabs cannot enter the crab nest body 10, and the green crabs can safely molt in the crab nests. And the green crabs can leave the crab nest from the crab collecting opening after being molted. In the period of no molting, the blue crabs can also hide in the crab nests for inhabitation. The crab nest is arranged in the cultured fish steak, so that serious loss of the blue crabs caused by shell-molting time residue can be effectively prevented, and the successful high-density culture of the blue crabs is ensured.

In this embodiment, a crab fetching opening 20 is formed in the top of the crab nest body 10, a manager can fetch the green crabs in the crab nest through the crab fetching opening, a sealing cover 21 is hinged to the right end of the crab fetching opening 20, and the left end of the sealing cover is connected with the top of the crab nest body through a hasp lock.

In this embodiment, the netting is a flaky net structure, and the netting around the cultured fish steak can be connected into a whole. It should be noted that the length of the netting is required to exceed the length of the climax, the length-width ratio cultivation float valves are respectively 0.5 m longer, a crab nest is placed in the range contained by the netting, and the crab nest is a structure which can not be entered by other green crabs after a single green crab enters, so that the green crabs can safely molt under the high-density cultivation mode.

In the embodiment, the cultured fish steaks are arranged on the beach, the netting around the cultured fish steaks directly extends to the beach and is buried more than 1 m deep into the beach to prevent the green crabs from escaping, the cultured fish steaks are bound and fixed through fixing pile ropes at the top corners of the periphery, crab nests are arranged in the culture areas of the cultured fish steaks, then the green crabs are put in, the best green crabs are put in more than 100 g, and the density is less than 10 green crabs per square meter of the beach. The daily bait is low-value shellfish and fresh trash fish, etc., the bait amount is about 10% of crab weight when the water temperature is above 20 ℃, and the bait amount is reduced appropriately when the water temperature is 15-20 ℃. Keep alive below 15 ℃, and feed once every several days. Due to the existence of the cultured fish steaks, managers can walk above the mudflats more conveniently to carry out operations such as feeding, catching and the like.

If the utility model discloses or relates to parts or structures which are fixedly connected to each other, the fixedly connected parts can be understood as follows, unless otherwise stated: a detachable fixed connection (for example using bolts or screws) is also understood as: non-detachable fixed connections (e.g. riveting, welding), but of course, fixed connections to each other may also be replaced by one-piece structures (e.g. manufactured integrally using a casting process) (unless it is obviously impossible to use an integral forming process).

In addition, terms used in any technical solutions disclosed in the present invention to indicate positional relationships or shapes include approximate, similar or approximate states or shapes unless otherwise stated.

Any part provided by the utility model can be assembled by a plurality of independent components or can be manufactured by an integral forming process.
