Description

Composite block for habitat of Serranidae and abalone and adherence of sea algae

The present invention relates to a complex block for the habitat of baridae fish and abalone and the algae epiphysis. More specifically, the upper surface is the attachment surface of Eckloniaceae, the upper small valley is the habitat of abalone, and the lower part is the habitat of fish of the family Baridae. It relates to a complex block for possible habitats of fish and abalones of the family Baridae and epiphysis of seaweeds.

Fishes of the family Baridae, such as scallops, sardines, and sardines, are coastal-settling fish species and have a high release effect. In the case of Jeju Island, it is continuously conducting a fry release business of bariridae fish, and it is expected to increase the income of fishermen. In 2020, 100,000 seeds were released to the fishing grounds around Jeju, including Javari (Dageumbari), Redbari, and Swordfish (Swordfish).

The characteristics of the fish of the family Baridae, such as the Jabari, Seongeo, and Hembari, are as follows.

First, they settle in one place due to coastal settlement.

Second, they live in rock caves, and the shape of the rock caves inhabiting them has certain characteristics.

Third, it is a nocturnal or daytime activity near its habitat, and is a carnivorous fish.

Fourth, it prefers an area where there is not a lot of algae, and inhabits a rocky burrow with a depth of 10m to 30m. They especially prefer shaded and hidden areas. Also, rock caves in soft rock areas with weak strength are preferred over hard hard rock.

On the other hand, more than 100 types of abalone are known around the world, and abalone, horse abalone, black abalone, rice cake clam, and rice cake clam are distributed along the coast of Korea. In particular, in Korea, abalone is an important aquaculture target species inhabiting the east and southwest seas, and artificial seedlings have been produced in earnest since 1976. Recently, abalone has been spotlighted as a new value-added variety, and local governments are favoring it as a popular variety with great added value as the most preferred target organism as part of a coastal resource creation project.

Abalone's habitat is between the crevices of rocks, and the characteristic of the crevices of the rocks is a V-shaped small valley.

In the prior patent, a slope is provided in Korean Patent No. 10-1104776, and it is made of a concrete material, a mixed material of concrete and stone powder, a mixed material of concrete, stone powder and shell powder nacre powder, or a natural stone stone ingot (stone) material. three-dimensional structure; a plurality of first form/hide parts formed in a tubular shape penetrating the front and rear parts of the three-dimensional structure and penetrating the inside of the three-dimensional structure; a plurality of second form/hide parts formed in a tubular shape penetrating one side part and the other side part of the three-dimensional structure and penetrating the inside of the three-dimensional structure; and at least one or more linear grooves formed on the lower surface of the three-dimensional structure, wherein the first form/hide part and the second form/hide part are arranged to cross each other at right angles, and the linear groove is the front part of the three-dimensional structure. It is made in a straight line shape continuously intersecting from one direction to the rear part direction, from one side part direction to the other side part direction, and the first form/hidden part has a size of 3 to 5 cm and a weight of 3 to where the front part or the rear part penetrates. Disclosed is a structure for habitat and hiding of sea creatures, characterized in that it includes a PE network circular penetrating cap that induces not to be lost to algae when releasing after accommodating 5 g of sea cucumber,

In Korean Patent No. 10-1327397, a plurality of first inflow passages are formed in a cylindrical shape, have a growth space inside, and form a vertical direction with respect to the inner center so that the inflow of seawater can be made, and the first inflow A first block body in which a plurality of second inflow passages formed in communication with the passage are arranged in a horizontal direction along an outer edge, and a radially arranged arrangement with respect to the inner center to support the lower end of the first block body and a plurality of second block bodies formed so that the first inlet passage and the second inlet passage and the third inlet passage are formed to communicate with each other so that the inflow and outflow circulation of seawater can be made in a horizontal direction. , The second block body is formed to protrude to the outside of the first block body, an artificial reef characterized in that the upper and side surfaces are formed in polygons having a plurality of curved surfaces is disclosed.

As described above, technologies for artificial reefs have been actively studied in the prior patents, but there are practically no artificial reefs having a structure suitable for the habitation of baridae fish and abalone by taking advantage of the habitat characteristics of baridae fish and abalone.

The present invention forms a plurality of V-shaped grooves in the form of small valleys in the upper part, and forms a passage in a bent form so that the inside cannot be seen in the lower part and an inner habitation part, so that the upper surface provides an attachment surface of E. The small valley provides a habitat for abalone, and the lower part provides a habitat for abalone, and a complex block for algae epiphysis and a mixed-use abalone that can be used simultaneously as a habitat for E. It is intended to provide

The complex block for the habitat of baridae fish and abalone and seaweed epiphysis of the present invention is a block body 10 of a concrete material in the form of a square or polygon,

A "V"-shaped upper inclined groove 20 that penetrates from one end to the other end in the upper portion of the block body 10 and is formed in a plurality of spaced apart from each other at regular intervals;

The complex block for the habitat of barlidae fish and abalone and seaweed epiphysis of the present invention has the following effects.

First, it has the effect of contributing to the resource recovery of baridae fish and abalone.

In Jeju Island, abalone seed pods and barley and fry are released as a resource recovery project. However, in order for the larvae and fry to survive after release, there must be an appropriate habitat at the release site. If released without such habitat, they serve as food for other fish species. Therefore, if the composite block of the present invention is installed and a discharge project is conducted around it, the resource recovery effect is increased.

Second, it has the effect of contributing to the healing of seaweed.

Sea urchins are the dominant species in the coastal green area, that is, the Baekhwa area, and sea urchins must be removed because they eat algae at random.

If the complex block of the present invention is installed in the green sea area and the dolphin release business is carried out to serve as a dolphin cave, the dolphin eats sea urchins and can be used for the purpose of creating a marine forest using natural enemies. Moreover, the upper end of the composite block of the present invention is in a form in which Ecklonia is easily attached.

Third, there is an effect that can be used for convergence purposes.

When the complex block of the present invention is installed, seaweeds such as Eckloniaceae are attached to the upper part, and shellfish such as abalone and pentagonal lobster live in the small valley at the upper part, and the lower part is not only bariidae fish, but also coastal settlements such as stone sea bream and bengedome. Adult fish live there. Therefore, since it provides a variety of habitats for marine animals and plants, there is an effect of restoring or enriching the marine ecosystem.

The inclination of the eaves wing 60 is a minimum of 10 degrees and a maximum of 70 degrees,

It is characterized in that the cylindrical through-hole (50) is formed to pass through.

The lower surface of the block body 10 is blocked or characterized in that it is formed by penetrating into the lower part of the inner template groove (40) to communicate with the inner groove (40).

It is characterized in that a plurality of the internal form grooves 40 are positioned inside the block body 10 to the left, right, or up and down.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

The present invention is to provide a multi-purpose block that can be used at the same time as an attachment surface of Ecklonia cava on the upper surface, a habitation of abalone in the upper valley, and a habitat of abalone in the lower part of the family Baridae. Igodiidae are completely carnivorous, so abalone and barlidae do not compete for food with each other, so they can share a habitat.

First, abalone and baridae fish prefer to live in areas with weak currents, so the habitats match.

Second, the depth of the habitat is about 10m, and it is a stone field, with sand around it and a lot of seaweed. They are nocturnal, hiding in their habitat during the day and active at night. They also spawn in their own habitat without moving far.

Third, fish and abalone in the family Baridae are in desperate need of resource recovery because they are produced in very small numbers in the wild.

Fourth, since they lead an independent life except during the spawning season, only a small number of individuals live in the habitat.

As shown in FIG. 1, the complex block for the habitat and algae epiphysis of abalone and abalone of the present invention produced using the characteristics of abalone and abalone is attached to the top, and seaweed such as Eckloniaceae is attached to the top, and The same shellfish inhabits in the upper valley, and the lower part is a block body 10, an upper inclined groove 20, a lower passage groove 30, and an internal habitat to provide a block for a mixed use where barley family fish can inhabit. It is composed of a groove (40) and a cylindrical through hole (50).

The block body 10 is made of concrete and is formed to have a rectangular or polygonal block shape, and the compressive strength of the concrete is made to have a high durability from 21 MPa to 40 MPa, so that it can be prevented from being easily damaged by a typhoon.

The block body 10 is a special concrete blended by mixing silica fume in the range of 3 to 10% by weight relative to the weight of cement as an admixture during manufacture so as to prevent contamination of the sea by inhibiting the elution of strong alkali (pH) of concrete. .

The upper inclined groove 20 has a "V" shape on the upper surface of the block body 10 to provide a habitat for abalone, penetrates from one end to the other end, and is formed with a plurality of spaced apart from each other at regular intervals.

Abalone generally inhabits between the crevices of rocks, and the characteristic of the crevices of the rocks is a V-shaped small valley. The valley must have a closed entrance.

The meaning that the entrance is closed means that, as shown in FIG. 2 , the entrance (B) should be deeper than 1 compared to the depth (H) (H/B), and the lower valley (C) should be a yaw. At least, the bottom (C) should not be more than 10cm.

If the entrance (B) is larger than the depth (H), abalone will never inhabit. This is because abalone inhabits by attaching to the sidewall of a small valley that is deeper (H) than the entrance (B). The reason is that if the depth (H) is deep, it can be concealed from the attack of natural enemies, and the influence of strong currents is small.

Even if the conch is turned over, it has a hard calcareous lid, which makes it easy to prevent fish attacks. However, abalone is easily attacked by fish such as stingrays because its vulnerable body is completely exposed when turned over. Therefore, if the habitat of abalone is V-shaped, it is selected as the habitat because it can easily return to its original position even if it is turned over.

Therefore, the upper inclined groove 20 is formed in a "V" shape taking advantage of the habitat characteristics of abalone, so that the influence of birds is less in the form of a small valley, and the abalone inhabits the side part of the upper inclined groove 20 easily. The upper inclined groove 20 may have a flat cross-section 200 with a predetermined width at the lower end or may be sharply formed in order to form a structure in which abalone easily inhabits.

As the upper inclined grooves 20 are formed at regular intervals, a flat protruding surface 100 is formed between each upper inclined groove 20 on the upper surface of the block body 10, so that Ecklonia, the food of abalone, can be easily attached. make it possible

As shown in Fig. 3 (Fig. 3A to Fig. 3D), the lower passage groove 30 is the block body 10 in order to serve as a passage through which barley fish can enter the internal habitat groove 40. Each of the plurality of sides from the lower side or the lower part is formed to a predetermined depth toward the inside, and one of the lower passage grooves 30 is most suitable so that no flow occurs therein, but up to four may be formed.

The lower passage groove 30 has a width and height of at least 10 cm to a maximum of 60 cm, and is formed in a square, round or oval shape so as to be suitable for entry and exit of barley and fish, and the inner end is bent at a certain angle toward the top or bottom. As to be formed, the shape of the lower passage groove 30 may be formed in various shapes such as a straight straight shape, a shape inclined toward the upper side, a shape inclined toward the bottom, etc. at the entrance side, and the end of the exit side generates a flow inside It is formed to be bent at a minimum of 30 degrees to a maximum of 150 degrees toward the upper or lower side so that the inner habitation groove 40 formed in the inside of the block body 10 is not visible from the inlet side, so that the inner habitat groove 40 is viewed at the entrance. make it impossible

The inner habitation groove 40 is formed in a circular or oval shape inside the block body 10 to provide a habitat for barley and fish, and the inner end of the lower passage groove 30 communicates with one side. .

The inner habitation groove 40 is formed with an inner diameter of at least 30cm to a maximum of 200cm in order to provide a space where adults of the family Baridae can sufficiently inhabit, and one or a maximum of 4 are formed in the inside of the block body 10. It may be formed, and when two or more internal grooves 40 are formed, they are each independently formed in the left, right or up, down or left, right, up, and down directions.

The inner template groove 40 is formed inside the block body 10, and the lower passage groove 30 communicating with the inner template groove 40 is formed by bending the end of the inner template connected to the lower passage groove 30. The groove 40 is provided in a structure similar to that of a rock cave for baridae fish, who prefer a burrow in a shady and dark bedrock, as a habitat, and there is no flow of algae inside, so it is very easy to use as a habitat for baridae fish am.

The inner habitat groove 40 can be formed so that the lower part penetrates to the lower surface of the block body 10, or the lower part of the internal format groove 40 is completely blocked so that the gap occurring at the bottom can be eliminated. have.

The cylindrical through-hole 50 is a configuration in which a plurality of cylindrical through-holes 50 are passed through the block body 10 in parallel in the horizontal direction. After inserting the pipe, it is configured for the purpose of easily transporting the block body 10 by connecting a rope to the steel pipe.

The cylindrical through-hole 50 is formed at a position that does not penetrate the internal habitual groove 40, and the steel pipe inserted into the cylindrical through-hole 50 usually has a diameter of about 4.5 cm. It is preferable to form a diameter of 5 to 6.5 cm.

On the other hand, as shown in Figs. 4 and 5 (Figs. 5A to 5D), the eaves wing 60 is formed in the direction in which the lower passage groove 30 is formed on the outside of the block body 10, The eaves wing 60 is a block body 10 on the upper side or a plurality of sides of the block body 10 in which the lower passage groove 30 is formed according to the inhabiting characteristics of baridae fish that prefer dark and shaded places. It extends from one side or a plurality of sides of the upper part to the height of the entrance of the lower passage groove 30 and is formed in a structure to conceal the lower passage groove 30, and as it moves away from the side of the block body 10 from the upper part to the lower part, It is formed to be inclined at a certain angle, the angle of inclination of the eaves wing 60 is formed in a range of at least 10 degrees to a maximum of 70 degrees, so that it is easy to conceal the entrance side of the lower passage groove 30 and block sunlight into the interior.

The eaves wing 60 is also formed through the cylindrical through-hole (50).

The complex block for the habitat of baridae fish and abalone and seaweed epiphysis configured as described above can be manufactured in various ways, but as a preferred example, a forced form is used for the outer form and the inner form for the formation of the inner habitation groove (40) It is desirable to manufacture the form by using a rubber-based tube or inflatable PVC to inject air when manufacturing the form, and then remove the internal form after pouring out the air after concrete pouring and curing is completed.

If we look at the natural marine ecosystem of Jeju, the habitats of baridae fish are various types of fish, and there are algae forests such as Gambaek and Mojabanae, and complex ecosystems are formed in stone fields and well-developed underwater fields. Therefore, the habitat of the Baridae fish of the present invention is also a habitat for shellfish such as abalone and pentagonidae, and it is necessary to provide a surface on which E. coccyx and mackerel can easily attach to it. Bariidae fish live in a space where seaweed can be attached more easily than can be used exclusively for barlidae fish, and it is a habitat for shellfish and where other fish species can nest well. In other words, the house is also a home, but the surrounding food environment must be abundant. For this reason, the complex block for the habitation of fish and abalone of the present invention is composed of a convergence space in which E. E.-abalone-fish can inhabit at the same time.

On the other hand, the present invention is configured to provide a habitat for abalone and baridae fish and an epiphysis of seaweed, but when installed in a coastal reef area, it can be used as a habitat for fish that live in a community such as stone bream or bengedome and run as a habitat for adult fish.

Depending on the surrounding environment of the location where the composite block of the present invention is installed, that is, the strength of birds, the number of rocks, the characteristics of food, etc., sea bream may inhabit in addition to fish of the family Baridae. Therefore, the composite block of the present invention can provide a habitat for fish of the family Baridae, but has a multi-purpose feature that can also provide a habitat for other fish species that have a burrow as a habitat.

And, as stone sea urchins are natural enemies, they can effectively control sea urchins that eat algae at random. Therefore, the wide upper space can be used as an attachment space for seaweeds, so it can be used as a structure for healing in the green area.

As described above, the present specification and drawings have been published for preferred embodiments of the present invention, and although specific terms are used, these are only used in a general sense to easily explain the technical content of the present invention and help the understanding of the present invention, It is not intended to limit the scope of the present invention. It will be apparent to those of ordinary skill in the art to which the present invention pertains that other modifications based on the technical spirit of the present invention can be implemented in addition to the embodiments disclosed herein.
