Description

{STRUCTURES FOR OYSTER FARMING}

The present invention relates to a virtual set-type oyster aquaculture structure, and more particularly to a virtual set oyster aquaculture which not only simplifies the assembling process of a structure but also significantly reduces the cost and time required for the closure and disassembly of the bastion network. Structure.

Among the aquatic life resources, Oyster is known as a complete food which is rich in various nutrients such as milk from the sea.

In Korea, oyster cultivation has a slight difference in the cultivation method to suit the characteristics of the marine environment and the difference of the tide level according to the region. Hereinafter, such conventional methods of producing a food product will be described.

One of the oldest methods of conventional cultivation methods, the so-called bottom-up style, is also known as a tidal dish, and cultivates oysters in the sea floor, which is several meters deep. At this time, the term "positive" refers to the growth of the oyster seedlings, which are young seeds, until harvesting. Such a sedimentation aquaculture method is a method in which a stone or shell used as an adherent substrate is introduced into the sea bed and adhered to the bottom of the sea bed. However, there is a disadvantage that the dialysis material may be buried or lost due to weathering, the purchase of the gypsum material is difficult, and the transportation of gypsum is difficult. In addition, there is a problem that economical efficiency is lowered because it is necessary to perform pre-dialysis and re-dialysis every year.

In addition, in the method of breeding the consecutive waxing ceremony, a plurality of knittings (rich) are held at regular intervals and inserted into an anchor line, and anchors connected to both ends of the anchoring line are inserted and fixed on the seabed. It is hung open at intervals so as to nurture seeds attached to the bottom of water. However, it is difficult to attach a large number of seedlings to the bottom of a single water stream, and labor-intensive work is required for mass production.

In addition, the raft aquaculture method is a method in which a plurality of transverses and interspecies are intersected with each other at an appropriate interval, and a rabbit (rich) is attached to the raft and floated on the water surface. And the shell was attached to the shell and cultured. However, since the raft harvesting method uses two-dimensionally connected rafts as floats, it is not suitable to be used in the growth of the frequent winds, and it is still labor intensive There is a problem requiring work.

As a result of the long-term accumulation of various wastes and excrements, the environment is deteriorated due to the long-term use of fisheries in limited waters and the production of oysters is decreased due to frequent diseases, and growth is slow There are many problems.

As a method of solving the problem of the conventional oyster cultivation method as described above, there is a virtual oyster cultivation method. The virtual oyster culture was developed to apply to the west coast tideland where the intertidal zone is relatively well developed. Unlike the water culture which is always kept submerged in the water, It is an eco-friendly way of farming.

Korean Patent No. 261,437 (a virtual set-type oyster aquaculture and method for producing one-oyster seeds and oysters for this purpose) developed by the applicant of the present invention by the prior art of a virtual oyster cultivation method, a registered patent No. 1,282,132 A set oyster aquaculture structure and its installation method for oyster cultivation).

1 is a perspective view showing a virtual set oyster culturing structure according to the prior art. 1, the conventional virtual set type oyster culturing structure comprises a support 110 formed continuously with a hollow cylindrical connection groove 111 spaced apart from each other by a predetermined distance, a support portion 110 bent downward from both sides of the support portion 110, A pedestal 100 for maintaining a predetermined distance between the bottom surface and the bottom surface of the pedestal 100 and a fixed part 130 for bending the end of the leg 120 and contacting the bottom surface, A plurality of hangers 200 slidably inserted into the hollow portion of the joining trough 111 at right angles to the joining trough 111 and a positive net 300 mounted on the hangers 200.

The virtual set type oyster augmenting structure according to the related art has an advantage that the manufacturing cost can be reduced by simplifying the assembling process of the structure by improving the fastening method of the base and the bar by the slide fastening method using the coupling groove.

Hereinafter, problems of the virtual set oyster culturing structure according to the prior art will be described. The conventional set-type oyster aquaculture structure according to the prior art is installed on a large scale in a coastal tidal flat farm when the assembly is completed on the land. At this time, four corners of the positive net are fastened to the strap 200 using corrosion-resistant coating wire to fix the positive net 300 to be put on the strap. However, in the conventional positive network connection method, positive networks can be lost due to waves and tidal currents. In the case of large-scale aquaculture facilities, it is necessary to repeatedly connect and disassemble the positive network, .

Normally, the work of fastening and dismantling the positive net is carried out about four times a year. And the working time is about 16 minutes per network. In this case, labor cost is high because one worker can work only about 15 nets during a day (based on a low water time of 4 hours) and there is a problem that a coated wire can not be rehabilitated once.

The following is the conversion of oyster farm site facilities. If 540 virtual sets are installed per 1ha, a total of 2,700 positive networks are required for 5 networks per set. In this case, the cost for the positive netting or dismantling work is 180 persons × 86,000 won / person = 15,480,000 won, and the coated wire 5,400m × 30 won / m = 270,000 won, totaling about 15,750,000 won.

That is, the conventional virtual set type oyster culturing structure has a problem in that it takes a lot of time and cost to fasten or dismantle the positive net.
