Parent shellfish breeding device for shellfish germplasm resource proliferation

Abstract

The invention relates to the technical field of shellfish culture, and discloses a parent shellfish breeding device for shellfish germplasm resource proliferation. The device comprises a connecting plate, a mesh cage body is arranged at the top of the connecting plate, a parent shellfish groove is arranged on the inner wall of the bottom of the mesh cage body, and a base structure in direct contact with the seabed is arranged below the connecting plate. The base structure and the connecting plate are connected together through a supporting structure. The parent shellfish breeding device has the characteristics that the parent shellfish is not easy to lose, the fertilization rate of the shellfish fry is high, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of shellfish culture, in particular to a shellfish breeding device for multiplication of shellfish germplasm resources. Background technique [0002] Shellfish multiplication and release refers to the value-added method of fishery resources that after shellfish are artificially cultivated, the cultivated seed is released into natural waters where shellfish resources have declined, so that the natural population of shellfish can be restored. [0003] At present, in the prior art, shellfish culture rafts or hanging cages are mostly used for artificial cultivation of shellfish. The shellfish culture raft is specifically a flexible structure frame formed by combining ropes and connected by ropes. , the frame of the flexible structure is positioned on the driven pile, and then the rope attached to the cultured target shellfish seed is suspended on the raft frame, so as to carry out artificial breeding; the hangin...

[0003] At present, in the prior art, shellfish culture rafts or hanging cages are mostly used for artificial cultivation of shellfish. The shellfish culture raft is specifically a flexible structure frame formed by combining ropes and connected by ropes. , the frame of the flexible structure is positioned on the driven pile, and then the rope attached to the cultured target shellfish seed is suspended on the raft frame, so as to carry out artificial breeding; the hanging cage is directly fixed by the rope. hang in the water, and then isolate a plurality of breeding cavities through partitions in the net clothes, and put shellfish seedlings in the breeding cavities to carry out artificial breeding; these two structures in the prior art are fixed On the sea surface, it is greatly affected by natural disasters such as typhoons, and due to the technical limitations of artificial breeding, the genetic diversity of cultured shellfish is low, and the recovery effect on natural marine shellfish resources is not obvious; Structure, such as Chinese patent announcement is a utility model patent of CN211832407U, it discloses a kind of modular intensive shellfish culture cage, this culture cage is to directly sink into the seabed for cultivation, not only can avoid the influence of typhoon, It can also avoid the impact of some environmental mutations on the sea surface on the shellfish; but the breeding cage is directly in contact with the seabed, and because the water flow on the seabed is relatively poor, it may make it difficult for the fertilized eggs of the shellfish broodstock to spread, thereby Affect the speed of natural population formation of shellfish. At the same time, being too close to the seabed will affect the survival rate of non-buried shellfish seedlings in culture cages.
