Description

Oyster Shell Reef {Artificial reef including oyster shell}

The present invention relates to an oyster shell reef, and more particularly, to an environmentally friendly artificial reef made to contribute to the protection and development of fish, especially fry, using oyster shells that cause coastal environmental pollution.

In general, artificial reefs are artificial structures that are installed on the coast or near the sea in order to secure marine resources for coastal fisheries, to provide spawning and habitat for marine life, and to provide shelter for fry. It has been conceived from the rule of thumb that if a ground structure is dropped into the sea, it can raise a lot of catches. In recent years, it has been transformed into various shapes such as those designed as hexahedral, cylindrical, and uneven structures in order to create a more efficient habitat for fish. come.

In addition, a variety of materials used to make artificial reefs, such as concrete, waste tires, steel, etc., each material has the following advantages and disadvantages in use. In the case of concrete, the structural stability is excellent, but there is a problem in that the concrete itself is toxic and it cannot be manufactured in various structures.In the case of waste tires, there is an advantage of recycling waste resources. It is insufficient to achieve the purpose of the reefs due to the high risk of movement and conduction.In the case of steel, it is possible to make a complicated reef, but the effect is alleviated by the removal of adherent organisms attached to iron oxide due to corrosion, etc. The disadvantage is short life.

The inventors have sought to recycle oyster shells, which are being disposed of hundreds of thousands of tonnes a year, in order to develop materials that can effectively achieve the objectives of fish. Currently, domestic oyster farms have a total area of 8,265 ha and oyster shells generated only in Geoje and Tongyeong areas of the south coast exceed 300,000 tons per year, but only some of them are recycled as oyster farms, gimpoza and fertilizers. It is becoming. Oyster shells that are buried or dumped on the shore by small fishermen due to excessive waste disposal costs have caused huge economic losses such as causing coastal pollution and causing red tide, which is the main cause of damage to the marine environment. It is urgently required.

Oyster shells contain a large amount of trace elements that help the growth of marine life such as calcium and magnesium, making them suitable for artificial reefs, and recycling them can remove coastal pollutants and reduce enormous fish waste disposal costs. It can also contribute to increasing income. Therefore, the development of artificial reefs using oyster shell is very timely and will meet the practical needs.

The present invention has been proposed to meet this need. By using a forced beam and a metal mesh, a oyster shell storage body having a predetermined shape is manufactured and densely mounted in the inside of the housing, thereby utilizing the oyster shell more effectively. Its purpose is to provide environmentally friendly oyster shell artificial reefs that are constructed and reproduced.

1 (a) is a basic oyster shell reservoir 10 according to the present invention and Figure 1 (b) is a double oyster shell reservoir (17). The basic oyster shell storage body 10 is provided with a storage frame 14 of a hexahedron in which a plurality of vertical forced beams 11 and horizontal forced beams 12 are connected and provided with a predetermined storage location 13 therein. The storage point 13 is densely packed with oyster shells (not shown), and the metal mesh 15 is attached to the circumference of the storage frame 14 to prevent the oyster shells from escaping from the storage portion 13. Meanwhile, the double oyster shell reservoir 17 is formed by connecting two basic oyster shell reservoirs 10 at predetermined intervals by a connecting forced beam 16, and viewed together with the basic oyster shell reservoir 10. It becomes the basic composition of the oyster shell fishery according to the design.

Oyster shells contain various elements necessary for the growth of aquatic organisms, and they are not only able to supply them continuously, but also have good utility in restoring marine ecosystems and creating fishery resources as they are beneficial to the growth of seaweeds as environmentally friendly materials. This oyster shell is recycled through the following process. First, the oyster shells collected at the dump are washed to remove foreign substances attached to the surface. This is because foreign matter such as does not help the growth of aquatic life. The washed oyster shells can be used after a long day (more than 1 month) sunlight drying and maturing in the yard, or the cleanly cleaned oyster shells can be used immediately.

On the other hand, as the metal mesh 15, an expanded metal produced by cutting a portion of the metal plate and extending horizontally to have a continuous mesh shape of diamond or rectangular shape is mainly used. In addition to the function of preventing the escape of the oyster shell, the metal mesh 15 is provided with a substrate in which a mesh shape is continuously formed so that algae can be easily formed. It allows you to fake it. In addition, since the metal mesh 15 is spot-welded to the forced beam, the bonding force is weak, so that the metal mesh 15 is separated, and thus the oyster shell filled in the storage frame 14 also falls to the bottom of the seabed. Therefore, if the oyster shell is installed on the bottom of the nisin or sani, the oyster shell that has fallen to the bottom of the sea is decomposed to bring about an effect of improving the lipids. The use effect of the metal net 15 is maintained for more than 10 years after the reef drop, and even after both the metal net 15 and the oyster shell fall off the oyster shell in accordance with the present invention can continue to function as a general forced reef .

The basic oyster shell reservoir 10 and the double oyster shell reservoir 17 configured as described above are used in combination with a predetermined shape.
