The present invention relates to forced reefs, and in particular, oyster shells (shells) or natural stones are arranged in multiple stages within the reefs to provide nursery for fry, spawning grounds for fish, and expansion of the habitat space of shellfish. Shell Dialysis Forced Reefs.

Recently, the company has been promoting sea ranching for offshore fisheries, and as part of the project, the artificial reef business has been continuously implemented. Artificial reefs (人工魚礁) is to build a meat house in the sea.

In other words, artificial reefs are artificial structures for increasing fishery resources in coastal waters, and are provided as a place for spawning or habitating fish and shellfish, and as a hiding place for protecting and nurturing young fish. Therefore, in the sea where artificial reefs are placed, phytoplankton and phytoplankton are concentrated, as well as fish refuges and spawning places are formed, forming a new fishing ground, and the catch rate is more than doubled.

These artificial reefs are divided into coastal reefs installed in water shallower than 20 m and offshore reefs installed at a depth of 20 to 50 m. Coastal reefs include attached organisms such as shellfish and algae, and larvae. Mainly aimed at younger fish, and offshore reefs are known as algae hitting the reefs, causing turbulent flows and vortices, and moving the nutrients accumulated on the sea floor to the upper part, resulting in a large breed of plankton. It will increase the productivity of coastal fisheries by creating an environment that enables them to do so.

As the material for making the artificial reefs, concrete, waste tires, steel, etc. may be used. In the case of concrete reefs, the structural stability is excellent, but considering the weight, etc., it is unsuitable for manufacturing high-rise reefs, and its structure is inevitably manufactured in a hemispherical shape or a box shape. Rather, the phenomena are causing pollution.

In the case of the reefs using waste tires, only the aspect of recycling is considered, and the shape itself is difficult to be deformed, which does not satisfy the proper function of the reefs.

As a result, compared to concrete, it is possible to form a complex internal space, which is relatively light, and a lot of forced reefs (鋼製 魚 礁) that provide a structure suitable for fish breeding is being produced as well as research on it.

Forced reefs are stronger than conventional concrete reefs, so that a small amount of material is required to make the same space volume, which can be enlarged, and the reefs can be installed on weak grounds.

In particular, iron ions eluted from the surface of forced reefs are essential nutrients of phytoplankton, and iron ions are continuously supplied from forced reefs to provide a good environment for the growth of seaweeds, which is more effective for fish nesting than conventional concrete reefs. There is.

The forced reef is mainly assembled to a certain shape of the section steel, by forming a plurality of sections in a square or polygon by fastening the frame is stacked in multiple stages to produce a jungle-like (JUNGLE GYM) similar form. . This steel can not only be manufactured in a variety of structures, but also lighter than the weight of concrete, it is easy to move to the place after shipment, and dissolves in marine water due to ionization of the water quality due to corrosion of steel over time There is an advantage.

However, in the form of such conventional forced reefs, the rich nutrients sinking to the sea bottom are introduced into the reefs, or the shading effect and the solubility effect and the adhesion surface are not maximized, so there is a limitation in providing a hiding place.

In addition, the conventional forced reef has a problem that the habitat space of living creatures, ie benthos (benthos) living in the water, such as shellfish, reptiles and insect larvae.

Accordingly, the development of forced reefs having a structure that can solve the above problems has emerged urgently.

The present invention was conceived in view of the problems and necessity of the prior art, the object of the present invention is to place the oyster shells or natural stones placed as a by-product after the production of oysters in the inside of the reefs, the nursery of the fry and the spawning ground of the fry It is to provide oyster shell dialysis forced reefs that can expand the habitat of birds.

Another object of the present invention is to provide a oyster shell dialysis forced reef that can expand the habitat space of benthic living in the water tank (Soy) by the use of the oyster shell and natural stone.

Another object of the present invention is to provide a oyster shell dialysis forced reef that can expand the habitat and hiding place of the fish by implementing the upwelling and shading effect in the reef.

The above object of the present invention is to provide a spawning or habitat for fish and shellfish in the reefs, the main body having a cube shape with an open upper surface; A plurality of frame members attached along a circumference of the fish body and having a trapezoidal shape; Panel members installed in a plurality of equal intervals along the horizontal direction of the frame member; A reinforcing member installed perpendicular to the panel member along a longitudinal direction of the frame member; Fish spawning and fry nursery means stored in the receiving portion between the panel member and the reinforcing member; And divided into equal intervals through a plurality of partition lines provided up and down and left and right, it is achieved by a oyster shell dialysis forced reef comprising a cover member connected to the upper end of the fish body.

Preferably the fish spawning and fry care means in this invention, it is characterized in that the oyster shell or natural stone.

In addition, the fish spawning and fry nursery means in this invention is characterized in that it is not installed adjacent to each other in the vertical or horizontal direction.

In addition, the forced reef in this invention, it characterized in that it has a square pyramid shape as a whole.

In addition, the fish spawning and fry nursery means in this invention, it is characterized in that it is deposited through the diaphragm in the receiving portion.

As shown in FIGS. 1 and 3, the fish body 11 has a cube shape with only an upper surface open, so that various kinds of fish can enter and exit the fish body 11 and form shellfish. This is possible.

The frame member 12, which is composed of a steel frame structural steel, is attached along the circumference of the fish body main body 11, as shown in FIGS. 1 to 3, and has a trapezoidal shape as viewed from the front, and a right triangle as viewed from the side. It has a shape.

In the present invention, four frame members 12 are attached along the circumference of the reef body 11 so that the overall shape of the forced reef 10 has a square pyramid shape. Accordingly, since the shape of the forced reef 10 has a stable structure, conduction of the forced reef 10 by external force is prevented in the water.

As shown in FIG. 1, the panel member 13 has a right triangle shape and is fixed at a plurality of equal intervals along the inner horizontal direction of the frame member 12, and the vertical direction of the frame member 12 is adjusted. Accordingly, the rectangular reinforcement member 14 is fixedly installed to be orthogonal to the panel member 13.

Accordingly, an accommodating part 15 of a predetermined space is formed between the panel member 13 and the reinforcing member 14, and the fish spawning and fry nursery illustrated in FIGS. 1 to 3 in the accommodating part 15 are formed. The means 16 are loaded through the diaphragm 17.

At this time, the fish spawning and cheering means 16 may be composed of oyster shell or natural stone. The oyster shell is generated as a by-product after the production of oysters, it is usually piled on the beach to damage the landscape and become a factor of environmental pollution such as odor.

In the present invention, by installing the oyster shell in the form of a box inside the frame member 10 to reduce the environmental pollution of the beach and to recycle resources, it is also possible to use natural stones in addition to the oyster shell.

In addition, since the oyster shell having a curved shape and the natural stone having various shapes are alternately stacked at a predetermined interval inside the frame member 12, the oyster shell and the natural stone portion in the forage 10 The shadowing effect and the uplifting effect are increased, and the oyster shell and natural stone make it possible to increase the attachment area for benthic creatures living in the cutlery, such as insect larvae, to increase the habitat space of the benthic creatures.

The fish spawning and fry nursery means 16 is preferably installed so as not to be adjacent to each other at a predetermined interval in the vertical direction or left and right directions. Accordingly, it is possible for the various fish and the fry to be spawned and nursed without interfering with each other in the respective storage units 15.

Meanwhile, as illustrated in FIGS. 1 and 2, a square cover member 18 is connected to an upper end of the frame member 12. At this time, the cover member 18 is partitioned at equal intervals through a plurality of partition lines 18a provided up, down, left and right, and an opening 18b having a rhombic shape is formed on the inner surface of the cover member 18.

Accordingly, various kinds of fish and fry can freely enter and exit the inside of the fish body 11 through the opening 18b. In addition, at the corners of the cover member 18, an isosceles triangle shaped iron sealing portion 18c serving as a sort of shielding plate is provided.
