Description

[0001] STRUCTURE FOR BREEDING INFILTRATIVE SHELLFISH [0002]

The present invention relates to a shell-positive structure for culturing an invasive shellfish, and more particularly, to a shell-positive construct constructed to easily acquire an invasive shellfish while providing an excellent growth environment for an invasive shellfish at a low water depth will be.

Shellfishes are classified into sessile shellfish that adhere to the attachment matrix in the water depending on the ecological characteristics of the shellfish, and burrower shellfish that invade the sea floor. There is a low-level invasive variety inhabiting in the insecticidal layer about 10 to 50 m in depth in the invasive shellfish. An example is elephant shellfish. Elephant shells are deeply submerged in the low water depths, buried deep inside the sand, and expose long water pipes to the sand surface. In the past, elephant shellfish were released to the coastal fisheries and cultivated and harvested. There was no suitable harvesting tool, and the diver entered the deep sea, sprayed water with a high-pressure sprayer, and collected sand. However, such a conventional art has a problem that it is very difficult to harvest an infested individual because of the concern of loss of an individual due to loss of an effluent.

Currently, extraction of elephant shellfish using a high pressure sprayer has been prohibited because of destroying the submarine ecosystem, and elephant shellfish are not currently circulated and are difficult to cultivate and harvest. Also, there is no prior art for transplanting and harvesting elephant shellfish in large quantities. Patent No. 10-2016-0052113, which is related to a shell positive structure, is not installed at low water depth, nor can it provide an environment suitable for an elephant shell living in sand. Also, it is not a structure that can easily collect elephant shells grown in the sand. Therefore, it is necessary to construct a structure capable of culturing and collecting shellfish growing in sand at low water depth.

It will be apparent to those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. something to do.

1, a shell-and-shell structure 1 according to an embodiment of the present invention includes a main body 10, a weight member 20, a sieve 30, a pile 40, and a buoy 50 .

The main body 10 is a plate-like artificial structure produced to provide an environment in which shellfish grow. The main body 10 has a hollow 101 formed in a vertical or horizontal direction to receive a stream of water or sand, And a shell receiving portion 103 which is recessed into the shell receiving portion 103. In this specification, the vertical direction is a direction perpendicular to the sea bed surface, and the horizontal direction means a direction parallel to the sea floor. The body 10 has a porous structure in which a hollow 101 is perforated vertically or horizontally, through which seawater or sand is allowed to enter and exit. The body 10 is preferably formed of a lightweight material that floats in water, and can be molded, for example, from a plastic material. Plastic is light and easy to manufacture because of its excellent moldability, low manufacturing cost, and easy transportation and installation. It also has excellent corrosion resistance and is suitable for underwater environment where the body is installed. In the present specification, only the case where the main body 10 is installed on the sea floor is mentioned, but it is needless to say that, in addition to seawater, it can be installed in fresh water to breed freshwater intruding shellfish.

The hollow (101) may be manufactured in various shapes and sizes to allow water or sand particles to enter and exit the body. For example, 0.5 to 5 cm in diameter.

Referring to FIG. 2, a shell-like receptacle 103 according to an embodiment of the present invention includes a plurality of through holes 1031 formed on a side surface thereof and a nonwoven fabric 1033 formed on a bottom surface thereof. The shellfish receiving section 103 provides a living space in which shellfish can settle and live. The shell receptacle portion 103 may be formed in a cylindrical shape having an empty interior. The diameter of the shell receptacle 103 may be suitably adjusted according to the type of shellfish, the flow of water, and the like. Preferably, however, the elephant shell may have a diameter of 15 to 25 cm. If the diameter of the shell receptacle portion 103 is too small, the growth of the shellfish can be restricted. If the shell receptacle portion 103 is too large in diameter, the space inhabited by the shellfish can easily be destroyed by the external environment. The shell receiving portion 103 may be disposed at the edge of the main body 10 for the sake of the stability of the main body 10 itself. The shellfish receiving portion 103 may protrude upward and be formed at a position higher than the portion other than the shellfish receiving portion 103 of the main body. It is preferable that the height of the shellfish receiving portion 103 is at least 30 cm or more so as to accommodate the large shellfish.

The sand is introduced through the through hole 1031 formed in the side surface of the shellfish receiving portion 103 and filled with a predetermined height, thereby establishing the growth environment of the shellfish. When the sand is accumulated at a certain height inside the shell holding part 103, the shellfish can dug on the sand or sand to settle and settle. It is needless to say that the number of shellfish accommodating portions 103 can be appropriately adjusted according to the number of individuals to be reared. Further, since the water flows into the through hole 1031, it is possible to purify contaminants and prevent oxidation of a low quality.

Preferably, a permeable material is attached to the bottom surface of the shellfish housing portion 103 to prevent the sand introduced into the shellfish housing portion 103 from being lost. For example, a nonwoven fabric 1033 having fine pores of 50 to 100 mu m can be used. In addition, the muller can use a jena canal or the like, and the cloth may be attached to the bottom of the shell receiving portion 103.

The main body may be composed of only the hollow 101 and the shell receiving portion 103 as described above but it is preferable that the handle 105, the small hole 107 and the leg 109 are further provided in terms of convenience of installation and stability .

The pores 107 may be formed in various sizes according to the size of the pile 40 inserted into the pores 107,

The handle 105 is formed on the side surface of the main body 10 and is easy to carry the main body 10 and can fasten the main body 10 to the other main body 10 to create a plurality of breeding environments. The plurality of main bodies 10 can be fastened according to the area to be breeded. The shape of the handle 105 is not particularly limited as long as the handle 105 can be fastened to the handle 105 of the other body 10. Referring to FIG. 4, a plurality of main bodies 10 are fastened to form a large breeding space. It is possible to form the shell-positive structure 1 having a desired size by a simple method in which the tabs 105 having the inverted structure are simply fitted to each other.

The legs 109 extend in the bottom direction from the lower portion of the main body 10 and are inserted into the soft ground easily because the end portions thereof are sharp and easy to level even on uneven bottoms. The legs 109 are firmly seated on the sand bottom and the body 10 is fixed.

When the shell-like structure 1 is submerged on the seabed in such a manner that the weight member 20 is coupled to the main body 10, it is particularly advantageous for the prospec- tion of the submerged shellfish 3 living in the lower layer. The weight member 20 may have sufficient weight to settle down on the sea bed 5, for example, a concrete layer laid on the lower surface of the main body. The weight member 20 can dig into the ground by its own load and settle on the floor. The main body 10 settled on the bottom 5 and fixed to the floor can be stably cultured while minimizing the influence of algae or water and protecting the infiltrating shellfishes 3 from external impacts.

Referring to FIG. 3, there is schematically shown an environment in which a molten metal 30 is located inside a shellfish receiving portion 103 and an intruding shellfish 3 actually lives in the net 30 in the sea floor. In each of the sifting mills 30, the shells of the infestation shellfish 3 are implanted. The screen 30 is formed with a frame for imparting a shape to the screen 30, and the entire surface or the surface except for the top surface is made of a mesh, so that water circulation between the inside and outside is free. The sand particles flowing into the sieve 30 through the shell storage portion 103 flow into the sieve 30 and accumulate. In this state, when a part of the sieve net 30 is buried in the sand layer, the catch of the infested shellfish 3 contained in the sieve 30 is fixed and grows in the sand layer. According to the present invention, since the shellfish is cultivated in the filter net 30, when the user removes the filter net 30 from the body 10, the shellfish in the filter net 30 can be immediately caught, Can be easily separated by hooking the grooves (301) so that shellfish can be easily collected. The filter net 30 may be formed of a mesh to permit the entry and exit of seawater and sand, and may be formed of a flexible material, for example, a PVC or a PE material.

The pile 40 may be further assembled with the main body 10 and the pile 40 may be inserted into the pores 107 formed through the one surface and the other surface of the main body 10, to be. The pile 40 may be made of a steel pile so that the main body 10 is stably fixed to the bottom of the seabed.

The buoy 50 may be made of a variety of materials, such as styrofoam or plastic filled with air, which can generate buoyancy. The buoy 50 may be connected to the body 10 via a sling or the like. The user can easily grasp the position of the positive structure as the buoy 50 connected to the body 10 marks the position of the body 10 at the sea level.

The shell-positive structure 1 according to an embodiment of the present invention may be further combined with a protective net having a circumference and a width that can cover the main body 10. The protective net can protect the body 10 from pirate creatures such as octopus and starfish. The protective net may be made of various shapes and materials to allow the entry and exit of seawater or sand.

5 and 6 illustrate a shell-and-shell structure 1 implemented as an embodiment of the present invention and installed on the sea floor. A pallet made of a commercially available plastic material was prepared as a main body 10, and three piles were piled up and down to form one structure. The parts to be pinched were bundled with a cable tie to minimize movement of the pallet. The height of the shell receiving portion 103 formed at the edge of the palette and the center thereof is about 30 cm. A plurality of bricks are joined as a weight member 20 on the floor. Referring to FIG. 6, a net for protection is formed by wrapping the entire pallet with a net, and a cloth for preventing sand loss is attached to the bottom surface of the bottommost pallet.

According to the shell-positive structure (1) according to the embodiment of the present invention as described above, it is possible to cultivate the shellfish in a large amount in a simple manner, which can be cultured in the sand bed (5) It is possible to protect the shellfish from living things. Also, the screen 30 can be separated, and the user can easily separate the screen 30 by using the collecting hook 7, thereby consuming less time and labor. As the water and the sand are passed through the hollow 101 and the shell receptacle 103 of the main body 10, an excellent growth environment in which the shellfish can settle and live in the main body 10 is established. The body 10 is formed of a light material and is easy to manufacture and transport, and can be combined with the weight member 20 to be settled on the seabed so that it is particularly advantageous for positively infiltrating shellfish living in a low level.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. It is to be understood that the invention may be variously modified and changed.
