Description

Fish reef for native fish protection

Field of the Invention [0002] The present invention relates to fish reefs, and more particularly, to an artificial fish reef for protecting native fishes from foreign fish species.

More specifically, the present invention relates to an artificial fish for protecting native fishes, which can protect native fishes from foreign fish species such as bass by providing a space in which native fishes can breathe, .

In general, artificial fish is an artificial structure that is installed in the sea to form habitat for various fish and shellfish and seaweed. It protects the fishery from the trawler with a great fishing ability and Kwon Hyeon-net and creates a shelter and spawning ground for various fishes and shellfish. Is used for the purpose of nurturing.

These artificial fishes are known as square artificial fishes, which form a frame of a hexahedron by using concrete or steel or waste vinyl resin, and hemispherical artificial fishes which form a passage through which fish can move in a hemispherical body. Retorts having various materials and structures are being developed.

There are a variety of techniques related to these artificial fishes including Patent Documents 1 and 2.

Patent Document 1 discloses a structure in which a plurality of logs and a plurality of logs each having a hollow square shape intersect with each other to form a hollow square body, And it is made up of stones to be filled. Since it is not toxic due to the use of natural materials, it does not pollute the sea water and the microorganisms are adhered well, so that it is possible to provide a very advantageous condition as a habitat environment of a fish,

Patent Document 2 discloses a unit module including a porous material formed as a bottom portion, an upper portion and a side portion and having an inner space, a porous material filled on the bottom portion, an artificial aqueduct provided in the inner space, and one or more openings formed on the upper and side portions. And a support member having one end connected to the first buoyancy member at the other end to the unit module and having an artificial ear splint.

Although these conventional artificial fishes can provide an environment favorable for fish to breed and breed, they are mostly used in the sea and there is no technique related to artificial fishes for protecting freshwater fish on land.

On the other hand, various kinds of foreign fish imported for edible or ornamental use are discharged to rivers and rivers, and various kinds of exotic fish breed in domestic rivers. Among such foreign fish species, especially for bass, And pyramid, which destroy the ecosystem, and native fishes are facing extinction crisis.

In order to reduce the number of bass, it is prohibited to release trapped bass. Techniques for capturing and eliminating these foreign linguistics species are being developed.

One of the methods of capturing foreign fish species is Patent Literature 3, which constitutes a gypsum for capturing a bass, which is submerged to the bottom of the water, and then artificially creates a minute vibration sound as if it were hit by the movement of a small fish using water or branches. This is about how to capture a bass or a blue gill by capturing a bass and taking a bass fishing gig, but this method uses human sense and has limitations in capture.

In addition, various efforts are being made to eradicate harmful foreign language species, such as the Korea Ecosystem Disruption Control Association, which aims to protect ecosystems, but the effect is still insufficient.

It is an object of the present invention to provide an artificial fish sanctuary for protecting native fishes from native fish species by allowing native fishes to escape and breed and habitat.

In more detail, the present invention is made up of a plurality of tubular nettings which gradually decrease in the width from the outside to the inside and gradually provide a space where native fishes can breathe, thereby protecting native fishes from foreign fish species such as Beth It is an object of the present invention to provide an artificial fish for fish protection.

In order to achieve the above-mentioned object, an artificial fish for domestic fish protection is related to a reptile for providing a space in which a native fish can hide from a carnivorous foreign fish species, A tubular network having a relatively small receiving space is provided inside a tubular network having a relatively large receiving space, and each tubular network is configured to have a small net surface .

One or more barbs may be formed between the nets of the tubular network to prevent intrusion of foreign species or escape of invading foreign species.

In the inner center of the fish reed, a multi-stage shelf for providing a resting place to the fish may be further provided. At least one shelf of the shelves is provided with a scattering groove, and scattering aggregates such as sand and gravel Can be filled.

As described above, according to the present invention, the artificial fishes for protecting native fishes are composed of a plurality of net-shaped nets which are oriented inward and gradually become smaller in width, thereby providing different spaces depending on the size of the native species, so that native species are hiding and protected from foreign species There is an effect that can be.

In addition, a shelf that can be used as a scattering space can be provided at the center of the inside of the fish catch so that egg can be protected from foreign fish or carnivorous species, thereby increasing the number of native fish species There is also.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

Like reference numerals are used for like elements in describing each drawing. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of artificial fish for native fish protection according to the present invention will be described in detail with reference to the accompanying drawings.

The artificial fishes for native fish protection according to the present invention are made up of a plurality of nets 11 to 1n made of nets and having different accommodating spaces.

That is, as shown in Figs. 1 to 3 and 5, a plurality of tubular nets 11 to 1n made of nets having different sizes from each other, (12, 13 ~ 1n). In other words, the net becomes gradually smaller from the outer tubular net 11 to the inner tubular net 1n, so that the inner tubular net 12-1n ), The smaller fish can get inside the innermost net (1n) to be able to breathe and be protected from larger fishes.

The artificial fish candle of the present invention can further form a barb 20 such that a fish entering the inside of the barb net or a fish externally from the inside can be caught and caught.

As shown in FIGS. 2 and 5, the barb 20 may be formed to face the inside of the net, or may be formed to face outside, though not shown.

Since the number of foreign fish species can be reduced as compared with the case where they are left intact, the number of native fishes eaten by foreign fish species can be reduced, The number can be relatively increased.

In addition, a multi-stage shelf 30 may be provided in the center of the artificial fish of the present invention to provide a rest to the fish.

The shelf 30 provides a more comfortable resting space for the fish. That is, since the nets 11 to 1n are made of mesh, the flow of water and sound can be transmitted inward, and sunlight can be introduced. Accordingly, even if the user hides inside the tubular nets 11 to 1n, he / she can not easily rest because he / she is exposed to external stimuli. Therefore, the shelf 30 is provided to provide a more comfortable resting space.

As shown in FIG. 4, the shelves 30 are installed in multiple stages, and the distances between the stages may be different from each other so that fish of various sizes can be used.

In addition, it is preferable that a scattering groove 30g is formed on the upper surface of the shelf 30 and the scattering aggregate capable of attaching a scattered column such as sand or gravel is filled.

The artificial fish for artificial fish protection according to the present invention is preferably made of a material resistant to corrosion by moisture. For example, synthetic resin or stainless steel may be used. As shown in FIG. 5, it is possible to fill the inner bottom with a weight 50 such as a stone to prevent it from being influenced by the flow of water, It may be fixed to the floor underwater by a fixing means.

In addition, normal fish are largely inhabited on the bottom of large fishes, and small fishes live in close proximity to water. If artificial fish candles are placed on the bottom of deep water, small fish can not use artificial fish candles. Therefore, it is necessary to float the artificial fishes near the surface of the water so that the small fishes inhabited near the water surface can live.

As shown in Fig. 6, a buoyancy body 60 such as an air bag or a buoy is provided on the top of the artificial fish candle as lifting means for floating the artificial fish candle near the water surface.

In this way, the artificial fish floating in the water by the buoyancy body 60 can be swept away by the flow of the water and float. Thus, the pull string 70 is connected to the lower part of the artificial fish string and the end of the pull string 70 is fixed to the bottom of the water, so that the artificial fish can be prevented from flowing by the water stream.

At this time, by making the length of the tow line connected to the lower part of the artificial fishes sufficiently long, the position of the artificial fishes can be automatically changed according to the variation of the water level of the artificial fishes, or the artificial fishes can be artificially adjusted And the like.

7, a camouflage material 80 such as an artificial aquatic plant is installed in a frame of a tubular network installed at the outermost of the tubular nettings 11 to 1n so that the artificial fishing can be harmonized with the natural environment So that the fish can naturally breathe, and the gastrointestinal product 80 is fixed to the frame by the engaging means so as not to be separated from the fish.
