Description

Fish reef for nurturing chionoecetes opilios}

The present invention relates to crab carcasses, and more specifically, by providing a structure capable of protecting and nurturing crabs in the waters where crabs are densely populated, by artificially protecting and nurturing the crab resources that are decreasing every year It relates to the crab carcasses that can promote the activation and luxury of.

In general, the crab is a crustacean belonging to the water crab and the crab genus. In the 1800s, many reports from various parts of the world were reported, but now they are classified into 5 species.

Also, in general, the marine environment generally lives at a deep depth where the marine environment is stable, and its distribution is limited to areas where there is little change in salinity at water temperatures of 1 to 5 degrees or less.

In other words, crab is widely distributed in the cold water region of the northern hemisphere, and is mainly distributed in the North American continental side of Korea's East Sea, Okhotsk Sea, Bering Sea, North Pacific Ocean, and North Atlantic Ocean.

In addition, in the case of Korea, the inhabitants mainly inhabit the sea depths of 200 to 500m, but the habitat depth becomes shallower toward the north, and inhabit the coast of several meters in the Bering Sea and the North Atlantic Ocean.

Among them, the red crab (Chionoecetes opillio) is distributed in the depth of distribution between 500 ~ 2,000m, which is deeper than the normal crab, and the main habitat temperature is known as 0.1 ~ 0.3 degrees.

In addition, the ecology of the crab lives in a group, and at the time of group formation, it is first distributed in the form of a mat of one or two layers, and after a while, a tomb shape having a diameter of 1 to 2 m and a height of 0.5 to 1 m is formed. Herds of tomb-shaped crabs are arranged at intervals of 1 to 2 m to form a group. At this time, the area of the entire population is generally about 2.2 ha, the number of the population is estimated to be about 100,000.

Here, one pile is formed of hundreds of individuals, and males move to the surroundings and mate with females that hatch external eggs to hatch the crabs. In this case, the number of males is only 1 to 10% of the number of females. In general, the hatching of the crab hatches in the seabed of 500 ~ 2,000m depth, and the larvae become plankton for 3 months, then transform into chige and enter into the sea life. .

In this case, the first spawning immediately after the adult is called adult spawning is called spawning, and in the East Sea, the spawning is carried out in summer from June to August, and the second and subsequent spawning are hard spawning, which are known to be carried out over the winter months from February to March. .

In addition, the crab that enters the sea life grows repeatedly while molting, and the female grows to adulthood at the 11th molting age after 10 molting, whereas males do not molt after that, whereas males continue to molt after that. Because of this, it is known that females and males have different sizes.

In addition, when the molting age approaches, new shells are formed under the old shells. These individuals are called double shells, and female double shells appear in spring and summer, and male double shells appear in autumn. Since there is no commodity value, it is set as taboo.

More specifically, the molting is done by separating the abdomen, called the two breastplate, from where the abdomen is contacted, and with the new individual coming out of it.

Moreover, the prey organisms of crabs are very diverse, including algae, crustaceans (shrimp, crabs, copepods, and crustaceans) and molluscs, and their predatory life consists mainly of benthic fish.

On the east coast of Korea, many benthic fishes, such as rubber crab 2-5 cm in length, are found in the contents of the crab, which are presumed to be the main predators of the crab, but their influence on resources is unclear. In addition, although adult formulations are estimated to reach a considerable amount, quantitative analysis has not yet been made.

However, in recent years, as the resources have generally decreased, there has been an increase in fishing competition among industries surrounding crab fishing, and there are more cases of illegal fishing of snow crabs. There are many cases of dumping at sea.

In particular, the crab is very important for the long-term growth crab, but currently no management measures are taken.

In other words, since the management of the crab fishery where the crab is mainly inhabited is not managed at present, the crab and even the crab are overfished by the indiscriminate overfishing of Chinese fishing boats and the fishing net of fishing nets. As the population gradually decreases, even the depletion of resources is a concern.

Therefore, in order to solve these problems, it is also necessary to provide a space for herds to live in the habitat of the crab, to prevent the overfishing of the crab by the fishing net and to damage the fishing net of the fishing net. It is desirable to install nursery reefs made to prevent them.

An example of the prior art for such nursery reefs is, for example, "multi-purpose artificial reef using a top-shaped reef block" as disclosed in Korean Patent Registration No. 10-1014848 (registered Feb. 08, 2011).

More specifically, the above-mentioned "multipurpose artificial reefs using a top-shaped reef block" of Patent No. 10-1014848, the conventional artificial reefs are actually because of its simple internal structure and narrow internal space, the breeding and life of fish In order to solve the problem that was not suitable for the fish, there is an internal structure that can secure enough internal space for fish to live and breed, but it is suitable for shellfish and algae, It is to provide an artificial reef.

To this end, the above-mentioned Patent No. 10-1014848 is an artificial reef that is dropped into water and becomes a vegetation space of aquatic organisms, and in the space partitioned with a frame, a plurality of top-shaped reef blocks connected integrally with each other are arranged Comprising a block inclined panel and a reef block bottom panel, and a pair of the reef block inclined panel is installed to be inclined to face each other on the bottom of the reef block bottom panel, the top type reef block, its size from the bottom up The tapered portion has a tapered shape so as to be narrower, and a pillar portion formed integrally in a rod shape on the upper surface of the tapered portion, and a connection portion is formed at the side of the tapered portion, so that the top-shaped reef block is parallel to the plane. In the state arranged in plural number so that the plurality is connected to each other integrally, The frame is an artificial reef, characterized in that combined with the top type reef block to surround the outer periphery of the plurality of top type reef block connected integrally to each other to form a reef block inclined panel and a reef block bottom panel Doing.

However, the above-mentioned "multipurpose artificial reef using a top-shaped reef block" of Patent No. 10-1014848 is configured to be suitable for living and breeding fish, and does not provide an environment suitable for the growth of snow crabs as described above. .

In addition, as another example of the prior art for artificial reefs, there is, for example, "triangular shellfish artificial reefs" as disclosed in Korean Patent No. 10-0913808 (registered on August 18, 2009).

More specifically, the "triangular shellfish artificial reef" of the Patent No. 10-0913808 described above, the conventional shell, algae artificial reef for the most water is installed in shallow shallow water because it is easily conducted or fell due to waves or algae There were many cases of defection, lack of functional and structural aspects of the reefs for the culture of shellfish, and the structure of seaweeds and kelp floating in the sea or seaweed caught in sea It is to solve the problems of the prior art that did not have this easy structure.

To this end, the above-mentioned Patent No. 10-0913808, in the artificial reefs submerged on the sea bottom, the reef body is formed of a pyramidal tetrahedron of triangular pyramidal or square pyramid shape, and the circumferential direction of the lower end of the reef body It consists of a plurality of pillars are integrally installed with the main body along the triangular shape, forming the wall of each of the reef body main body formed in the center of the unit bulkhead in order to provide shade to the inner space of the reef Disclosed is a triangular algae artificial reef, characterized in that the intermediate triangular opening to be formed, and a pair of bottom triangular openings formed at the lower end of the unit partition wall.

However, the "triangular shellfish artificial reef" of the Patent No. 10-0913808 is also configured to be suitable for the growth of shellfish, and is not intended to provide an environment suitable for the growth of snow crabs as described above.

In addition, as another example of the prior art for artificial reefs, there is, for example, a "large equilateral triangular pyramid artificial reef" as disclosed in Korean Patent Registration No. 10-0890281 (2009.03.17. 2009 registered).

More specifically, the "Large forward triangular pyramid artificial reef" of the above-mentioned Patent No. 10-0890281, the conventional equilateral triangular pyramid artificial reef, the triangular pyramid auxiliary plate is installed on the vertex portion of the regular triangular pyramid skeleton and the appearance of the shadow and As the appearance due to the unevenness is prominent, the fish can be effectively confined to the corresponding area, but such shadows and unevenness do not exist in the central part of the equilateral triangular pyramid skeleton, which occupies a large part of the reefs. As a standard, it is intended to solve the drawback that the visual inducement effect and the facility effect due to fish overfishing are somewhat reduced, and sufficient shading for hiding of young aquatic organisms such as fry is not provided.

To this end, the registered Patent No. 10-0890281 is an artificial reef that is manufactured in an equilateral triangular pyramid shape based on an equilateral triangular pyramid frame that is a skeleton of an equilateral triangular pyramid shape, the side and bottom of the artificial reef by the equilateral triangular pyramid frame An inverted triangular frame is installed to be intersected with an equilateral triangular pyramid frame in an interior of a tetrahedron formed over a portion, and the inner space of the artificial reef is four triangular pyramid-shaped outer reef spaces by the equilateral triangular pyramid frame and the inverted triangular frame. It is divided into one inner forging space, and each of the outer reef space is inserted into a triangular pyramid-shaped reef block for each vertex portion is connected to each frame and installed integrally, a plurality of each reef block Flow passages are formed through the insertion direction of the reef blocks, and along the edges of the respective reef blocks. It discloses a large positive triangular Artificial Reef characterized in that the stepped edge is formed to be projected from only eocho block.

However, the "large equilateral triangular pyramid artificial reef" of the above-mentioned Patent No. 10-0890281, like the conventional artificial reefs described above, is made only for the purpose of collecting fish, and provides an environment suitable for the growth and protection of the crab It was not intended.

As described above, in the past, various kinds of reefs have been provided, but no dedicated reefs have been provided that are suitable for the growth and protection of snow crabs.

In other words, in order to improve the habitat environment of crabs, protect and nurture crabs and crabs, we have developed a crab nursery dedicated to the crab and install them in the main habitat of crabs to provide a growing space for snow crabs. It is desirable to provide private crayfish weeds that can be protected from overfishing to prevent overfishing or overfishing, and to prevent population declines to protect and nurture resources and ultimately contribute to the income increase of fishermen. As a result, there is no dedicated ground that can satisfy all such demands.

The present invention aims to solve the problems of the prior art as described above, and therefore, an object of the present invention is to provide a structure that can protect and nurture crabs in a dwelling area where crabs are densely populated, thereby reducing the amount of snow crabs that are decreasing every year. By artificially protecting and fostering fisheries, it aims to promote industrialization and luxuryization through the establishment of systematic production systems and systematic management of large crabs, and to provide crayfish that can contribute to increase fishery income by improving productivity.

In addition, another object of the present invention, by gathering the grown snow crab in a square-shaped house-shaped structure, to protect the snow crab from the net fishing or natural enemies, the interior of the structure can be used as a spawning ground and breeding ground of snow crab It is usually intended to provide nursery fish.

In order to achieve the object as described above, according to the present invention, in the crab carcasses to provide a space for the growth of the crab is installed in the habitat of the crab, form a house-like structure for the care of the crab Nursery fish frame having a space; A plurality of water holes formed on side and top of an outer wall of the nursery reef frame to facilitate the flow of seawater within the nursery reef frame; And crab nursery is provided, characterized in that it comprises a plurality of entrances formed on the lower side of the nursery reef frame to facilitate access of the crab.

Here, each of the through-holes, characterized in that the net is installed to smooth the flow of the seawater inside the nursery reef frame, and at the same time to protect the external natural enemies and pirates from entering.

In addition, the crab nursery reefs, characterized in that it further comprises a connecting ring formed on the upper end of the nursery reef frame to facilitate the transportation and installation of the crab nursery.

In addition, the crab nursery reefs, and further comprises at least one pillar formed to support the nursery reef frame, each hook to facilitate the transport and installation of the crab nursery reefs on top of each pillar Characterized in that is installed.

Furthermore, the nursery reef frame is characterized in that it further comprises a feed container is installed to put the food for the collection of the crab.

In addition, the nursery fish frame is characterized in that it is formed to have a bottom surface.

In addition, the nursery fish frame, the upper portion is characterized in that the upper end is formed in a tetrahedral shape cut.

Further, the nursery reef frame is characterized in that it is formed of concrete or cement.

As described above, according to the present invention, by collecting the crab in a square-shaped house-shaped structure to protect the crab from the net fishing or natural enemies, the interior of the structure can be used as a spawning ground and breeding ground of the crab By so doing, it is possible to provide the crab nursery fish suitably configured to protect and nurture the crab.

Therefore, according to the present invention, by putting the crab carcasses as described above into the waters where the crabs are densely populated, artificially protect and nurture the resources of the crab that are decreasing every year, and build a base system that enables continuous production of crabs and systematic management It is possible to improve productivity and luxury through industrial activation, which can contribute to increase in fishery income.

In addition, according to the present invention, by installing the crab carcasses configured as described above, to protect the crab and crab currently threatened with extinction due to overfishing, and through the investigation and monitoring of the crab resources and environment, ecology and production You can usually manage your resources.
