Description

Artificial reef of square type}

The present invention relates to an improved rectangular fish reef, and more particularly, by improving the conventional rectangular fish reef structure to prevent subsidence in soft ground, to provide a space for fish and shellfish to inhabit, and to protect fishery resources by creating a marine forest. It is about a square fish reef that can be nurtured.

In general, artificial reefs are composed of artificial structures to increase fishery resources in coastal waters, and are provided as a spawning or habitat for fish and shellfish, and are provided as shelters to protect fry and adult fish.

Such artificial reefs can be expected to increase the efficiency of fishing due to resource growth and fish groups, and to shorten the fishing time due to the proximity of fishing grounds. In particular, in the sea area where seaweed rusting (whitening phenomenon) has occurred, the effect of preventing seaweed rusting in coastal waters can be expected through transplantation and cultivation of seaweed.

Recently, useful seaweeds such as seaweed, kelp, rhubarb and other useful seaweeds that have been living on the coast have disappeared due to the transition of seaweeds due to the strong Kuroshio warm current, the Elliño phenomenon, and other environmental pollution. Due to the mass reproduction of lime coral algae, a lot of rusting (whitening phenomenon) that covers the bedrock is occurring.

Although the exact cause of this bleaching phenomenon has not yet been identified, it is cited as the cause of the increase in water temperature and inhibition of photosynthesis of algae due to the spread of Kuroshio turbulence and environmental changes. The bleaching phenomenon is rapidly spreading in the east coast and the coast of Jeju, and the coastal fisheries are deteriorating, and seaweeds such as seaweed and kelp are rapidly decreasing, and the habitat environment for useful shellfish and fish such as abalone and conch that feeds on seaweed is reduced. As it is worsening, fishing income in coastal waters is decreasing.

One of the ways to restore fishing grounds where bleaching has occurred is to install fish reefs, which are artificial structures.

Usually, artificial reefs are divided into coastal reefs installed within 15m of water depth and offshore reefs installed in 15-70m depth. Coastal reefs mainly target attached organisms such as shellfish and algae, and young fish such as fry. In fish reefs, as the algae collide with the reefs, dragons and eddies occur, and through this, nutrients accumulated on the sea floor are floated to the upper layer, thereby creating an environment in which various planktons can multiply, thereby enhancing the productivity of coastal fishing grounds.

There are various types of artificial reefs, and among them, square artificial reefs are representative.

A conventional rectangular artificial reef is disclosed in Korean Patent Registration No. 10-0787828.

The artificial reef has a structure in which the inside is hollow in the shape of a hexahedron and holes are formed on each side. These conventional artificial reefs have a small contact area with the bottom, so that they are easily settled in soft ground such as pearl or sand. In addition, there is a problem that it takes a lot of time to create a marine forest.

Hereinafter, an improved square fish reef according to a preferred embodiment of the present invention will be described in detail.

The improved square fish reef of the present invention is used for the habitat of fish and shellfish and for the composition of marine forests.

1 to 3, the improved square reef 10 of the present invention includes a hexahedral body 20 with an empty inside, an opening 25 formed on each side of the body 20, and the body 20 ) Is provided with protrusions formed by protruding at regular intervals on the slopes excluding the front and rear surfaces.

The body 20 is formed of concrete and has a hexahedral structure with an empty inside. Since the interior of the main body 20 is empty, it provides a space in which fish and shellfish can inhabit or hide.

In the illustrated example, the main body 20 is a hexahedron having a rectangular shape. Openings 25 are formed on the six surfaces of the main body 20, respectively. That is, the main body 20 has an opening 25 formed on each surface. The opening 25 may be formed in an octagonal shape or a square shape. In the illustrated example, the opening 25 is formed in an octagonal shape. The octagonal opening 25 can increase the area without reducing the strength of the edge portion of the main body 20.

The opening 25 is formed in the same size in the center of each side. The body 20 penetrates through the openings 25 in the front-rear direction, the left-right direction, and the vertical direction. Accordingly, fish and shellfish can freely enter and exit the inside and outside of the body 20 in any direction through the opening 25. In addition, the distribution of seawater is made smoothly through the openings 25.

The body 20 is formed with a protrusion. The protrusions are provided on the slopes excluding the front and rear surfaces of the main body 20, that is, on the left and right surfaces, and on the upper and lower surfaces.

The protrusion includes a plurality of protruding jaws 31 and 35. Each of the protruding jaws 31 and 35 is formed to protrude outward from the main body 20. The protruding jaws 31 and 35 allow the main body 20 to greatly enlarge the contact area with the underwater floor. When the floor is installed on a soft ground such as pearl or sand, it is possible to effectively prevent the subsidence of the main body 20 by distributing the load of the main body 20 widely. It makes it easy to settle in place and secures stability due to increased ground friction.

The protruding jaws 31 and 35 may be divided into corner protruding jaws 31 and square protruding jaws 35 according to their positions.

The corner protruding protrusion 31 is located at the edge of the slope of the main body 20. In the illustrated example, corner protrusions 31 are formed at four corners where the slopes of the main body 20 contact each other. The corner protruding protrusions 31 are formed long back and forth from the front to the rear of the main body 20. These corner protruding jaws 31 serve to reinforce the corner portions of the main body 20. Meanwhile, as shown in FIG. 10, the corner protruding protrusions 32 may be formed side by side adjacent to the corners with the corners interposed therebetween.

Referring back to FIGS. 1 to 3, the rectangular protruding jaws 35 are formed between the corner protruding jaws 31. Square protruding jaws 35 are formed on each slope of the body 20 with the opening 25 therebetween.

In the illustrated example, two square protruding jaws 35 are formed to face each other by being positioned in front and rear with the opening 25 interposed therebetween. One side of these square protruding jaws 35 is located in contact with the opening 25. Each of the rectangular protruding jaws 35 has a trapezoidal shape whose cross section gradually narrows as it progresses toward the end.

Since a recessed space is formed between the square protruding jaws 35, it is easy to incubate shellfish such as abalone and conch. The recessed space between the square protruding jaws 35 may also be used as a collection space in which organic substances settled in seawater are collected. Organic substances floating in seawater by the ocean current collide with the main body 20 and the organic substances are collected into the empty space between the square protruding jaws 35. When organic matter accumulates, planktons that live by eating organic matter are gathered, and fish and shellfish, which are the top predators of plankton, naturally gather into the square fish reef (10), providing a food supply for many fish and shellfish.

As described above, the present invention can provide a space in which fish and shellfish can inhabit or hide at the same time while preventing subsidence in soft ground by improving the conventional rectangular fish reef structure.
