Example Embodiment

[0026] The invention aims to solve the problems of high mortality, low recovery rate, and high cost of harvesting methods due to the existing methods of cultivating Yezo scallops that are either too much affected by the environment or restricted by the substrate conditions. The submarine cage culture device, a method similar to bottom sowing cage culture, puts scallops in a "cage" formed by netting. The specific technical solutions are as follows:

[0027] A submarine cage culture device for Ezo scallops, comprising a net, a support frame, a sealing tube, the support frame is placed in the net and connected to the net to support the net, the sealing tube is used to seal the net, and the support frame adds a net The three-dimensional height is conducive to the mouth-opening of shellfish.

[0028] The subsea cage culture device of the present invention can not only avoid the problem of raft-type culture being affected by surface water temperature fluctuations and high temperature in...

Abstract

The invention discloses a seabed cage-breeding device for comb shells and solves the problems that in the prior art, the breeding type is easily affected by environment, so that the death rate of the comb shells is high and the profit is low. The technical scheme of the invention is that: the seabed cage-breeding device comprises a netting, a support frame and a mouth-closing tube, wherein the support frame is arranged in the netting and connected with the netting to support the netting, and the mouth-closing tube is used for closing the mouth of the netting. The invention designs the novel seabed cage-breeding device; by adopting the seabed cage-breeding method, not only the problem that the raft breeding is affected by the surface temperature fluctuation and high water temperature in summer is solved, but also the problem of low recapture rate existing in the bottom sowing enhancement breeding method is also solved, the survival rate of scallops is high and the breeding density of young comb shells can be self-controlled according to actual conditions.

Description

technical field [0001] The invention belongs to the technical field of scallop cultivation, in particular to a seabed cage cultivation device for Ezo scallop. Background technique [0002] Patinopecten yessoensis is a cold-water shellfish with the advantages of large size, fast growth and high economic benefits. Since it was introduced into my country in the 1980s, after years of technical research and research, breakthroughs have been made in artificial breeding and breeding technology, and it has been cultivated on a large scale in Liaoning, Shandong and other places in my country, bringing huge economic benefits. and social benefits. At present, the aquaculture output of scallops in the North Yellow Sea has reached 150,000 tons per year. [0003] The current culture methods of scallops mainly include two types: raft culture and bottom sowing multiplication. Due to the influence of water temperature fluctuations and high temperature in summer, raft farming has a high mor...
