Device for culturing Patinopecten yessoensis

Abstract

The invention relates to a device for culturing Patinopecten yessoensis, which comprises a first net. The device is characterized in that the device also comprises a plurality of second nets and a frame; the first net is tightened up and smoothly fixed in the frame; the second nets are sewn and fixed on a body of the first net respectively and form a plurality of net bags mutually spaced in turn with the first net; and one side of each net bag is provided with an openable bag mouth. The device has the advantages that the device is simple in structure, easy to manufacture and low in cost, effectively prevents the mutual collision and occlusion among scallops from causing injury to shells and soft tissues, greatly improves survival rate, reduces production management operation, lowers labor intensity, has strong wind-wave resisting capability, is applicable to environment conditions with rapid flow and high waves in deepwater areas, and is favorable for further enlarging culture range.

Description

technical field [0001] The invention relates to the cultivation of scallops, in particular to a cultivation device for Ezo scallops. Background technique [0002] Patinopecten yessoensis belongs to the phylum Molluscs, Phallobranches, Scallopidae, and the genus Patinopecten yessoensis. It has the advantages of fast growth, large size, delicious taste, and high nutritional value. It is an important economic shellfish. Ezo scallops are a low-temperature species native to the coasts of Japan and Russia. Introduced into China in the 1980s, it began to be cultured in Liaoning, Hebei, Shandong and other northern coastal areas in the northern part of the Yellow Sea, and soon became one of the main species of shellfish cultured. [0003] At present, the cultivation of scallops mainly includes bottom sowing cultivation and sea floating raft suspension cultivation. [0004] Bottom sowing culture is to choose sandy mud bottom fishing grounds to remove harmful organisms. According to ...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome in the prior art the cultivation of scallop scallops that are not resistant to wind and waves is easy to cause losses, the cost of pocket net cultivation is relatively high, the operation is relatively complicated, and it is easy to attach miscellaneous shellfish and algae to affect the exchange of water bodies, and the survival rate of lantern net cage cultivation is low. Inverting the cage to reduce the culture density will increase the workload and the demand for culture equipment and the inversion of the cage will have a negative impact on the scallop. The invention provides a culture device for the Ezo scallop. The culture device for the Ezo scallop not only has a structure Simple, low cost, easy to manufacture, and smooth water body, high survival rate of Ezo scallop, high breeding efficiency, low labor intensity of workers
