Description

Sea turtles {artificial reef for sea cucumber}

The present invention relates to a sea cucumber reptile, and more particularly, to a sea cucumber reef fish that can provide a safe space for sea cucumbers by installing fishing reeds utilizing coal ash and steel making slag in the sea, .

As the demand for marine products such as sea cucumbers is greatly increased, the income of fishermen is greatly increasing. Interest in health and wellness is increasing in the echinacea, and sea cucumber is the best stamina food like sea ginseng in Korea and China. Popularity is increasing day by day. Especially, sea cucumbers are the fish products preferred by Chinese people.

However, in recent years, due to the strong winds of Kuroshio currents, the El Niño phenomenon, and the environmental pollution of trains, the seaweeds that have been inhabited by the existing coasts, such as seaweed, kelp and rhubarb, have disappeared. (Algae whitening), in which the coral algae propagate in large quantities and cover the rock.

These bleaching phenomena have yet to identify the exact cause, but they are attributed to the spread of Kuroshio turbulence and the rise in water temperature due to environmental changes and the inhibition of photosynthesis of seaweeds. The whitening phenomenon is spreading rapidly on the east coast and the Jeju coast, and the coastal fisheries are being devastated. The seaweeds such as seaweed, sea tangle and so on are drastically decreased, and the habitat environment of sea creatures such as sea cucumbers, abalone, Fishery income is declining.

The whitening phenomenon is spreading rapidly in the East Sea coast, and the coastal aquaculture is devastated and the seaweeds such as seaweed and kelp are rapidly destroyed, which has a considerable influence on the marine ecosystem including the change of the food chain structure and various fish spawning and habitat It is true. In the waters where the whitening phenomenon occurs, not only depletion of marine resources but also eutrophication is promoted, and it is known that natural healing is impossible without artificially restoring them.

Artificial fish, which is an artificial structure, is installed in the sea to restore the degraded sea environment and to create fisheries resources.

Artificial fishes are artificial structures for increasing fisheries resources in coastal waters, and they serve as shelters or habitats for sea creatures and as a sanctuary to protect fishes and fishes.

Such artificial fishes can be expected to have an effect of increasing the efficiency of fishing by the resource multiplication and fishery communities, and can be expected to shorten the fishing time due to the proximity of the fishing grounds. In particular, it is expected that the effect of preventing seawater from coastal waters can be expected by transplantation and cultivation of seaweeds in the sea area where the shrubs occur.

However, the artificial fish which has been developed so far is focused on the composition of sea crab and the protection and habitat of fish and shellfish, as in the Korean Patent No. 0988360, and it is in desperate need to develop artificial fishes suited to the characteristics of sea cucumbers.

It is an object of the present invention to provide a sea cucumber fishing net that can protect and create coastal fisheries resources by providing a safe space for sea cucumbers to be installed in the sea.

1 to 3, a circular sea creeass reed 10 according to an embodiment of the present invention includes a main body 20, a hiding space 21, a concealing member 40, a supporting chin 25 An upper flow path 30, and a lower flow path 35. The lower flow path 35 is formed by a plurality of through-

The main body 20 is formed of a concrete material and forms a skeleton of the sea cucumber fish catch. Particularly, it is preferable to add steel-making slag and fly ash to the concrete composition for manufacturing the main body. By recycling steel slag and fly ash from industrial waste, it is possible to provide eco-friendly sea turtles. In particular, the iron content in steelmaking slag has the effect of preventing whitening and promoting the growth of marine life. In addition, coal fly ash is lower in weight than ordinary aggregates, and it can alleviate erosion of fishing reefs in tidal flats and sand layers.

The main body 20 may be formed in various shapes. In the illustrated example, the body 20 is circular, but may alternatively be hexagonal or octagonal, as shown in Figs. 4 and 7. It is needless to say that the body can be made of a square.

The main body 20 is formed so that its bottom surface is flat so as to be easily seated on the seabed. The main body 20 is formed to have a wide width and a low height. The main body 20 is advantageous in that its center of gravity is low so that it can be easily guided since it has a sense of stability. Preferably, the surface of the body 20 may have a porous structure for easy dissemination of seaweeds. Although not shown, one or more pulling hooks for pulling may be provided on the top or side surface of the main body 20.

The hiding space 21 is located at the center of the main body 20. The cover space 21 is formed through the lower portion of the main body 20 at the lower portion thereof. Since the upper portion of the covering space 21 is sealed by the covering member 40, it provides a safe hiding place for the sea cucumber. It is of course also possible to provide shelter for benthos or shellfish.

A cover member 40 is coupled to the main body 20 to prevent the upper portion of the cover space 21 from being exposed to the outside. The cover member (40) has a structure that is coupled to the upper portion of the main body (20) to cover the cover space (21).

The concealing member 40 is composed of a plate-shaped panel portion 41 and a long hole 45 formed in the panel portion 41.

The circular panel portion 41 is formed larger than the diameter of the shielding space portion 21. And the long sheets 45 are formed so as to penetrate the panel portion 41 up and down. The seawater can circulate smoothly through the field study (45). It is preferable that the gutters 45 are formed long before, after, or laterally so as to block large predators from entering the sinking space 21. The long sheets 45 may be formed of one or more than two sheets in the panel portion 41. [

A supporting jaw 25 is provided on the main body 20 so that the edge of the panel portion 41 can be engaged with the main body 20 when the cover member 40 is coupled to the upper portion of the main body 20. [ The supporting jaw 25 is formed on the upper portion of the covering space 21.

An upper flow passage 30 and a lower flow passage 35 are formed in the main body 20 so that the sea compartment can communicate with the outside of the main body 20 by allowing the sea caves to pass therethrough.

The upper flow path (30) is formed on the upper surface of the main body (20). The upper flow path (30) is formed as a depressed groove downward from the upper surface of the main body (20). The depth of the upper flow path (30) is 1/3 to 1/2 of the height of the main body (20). In the illustrated example, the cross section of the upper flow passageway 30 is formed in a U-shape. The inlet of the upper flow path (30) is located on the side of the main body (20).

A plurality of upper flow passages 30 are formed. In the illustrated example, three upper flow passages 30 are formed, which are arranged at regular intervals of 120 degrees.

The upper flow path (30) forms a trapping space in which organic substances precipitated on the concave depression structure are trapped. Organic substances floating in the seawater collide with the main body 20, and organic substances are collected in the upper flow path 30. The organic material accumulated in the upper flow path 30 collects the microorganisms and provides the food supply source of the sea cucumber.

The lower flow path (35) is formed on the bottom surface of the main body (20). The lower flow path (35) is formed as a depressed groove upward from the bottom surface of the main body (20). The depth of the bottom of the lower flow path 35 is 1/3 to 1/2 of the height of the main body. In the illustrated example, the cross section of the lower flow path 35 is formed in the ∩ shape.

A plurality of lower flow passages 35 are formed. In the illustrated example, three lower flow passages 35 are formed, which are arranged at equal intervals of 120 degrees. Due to the nature of the sea crawl that crawls on the floor, the lower channel (35) mainly serves as a passage for sea cucumbers.

The lower flow path (35) is staggered with the upper flow path (30). That is, one lower flow passage 35 is located between the two upper flow passages 30. 2, the upper flow path 30 and the lower flow path 35 are arranged in a shape facing the center of the main body 20, that is, radially. By this radial structure, the cover space 21 and the outside of the main body 20 are easily connected through a plurality of paths.

When the circular sea cucumber reptile of the present invention described above is installed in the sea, the sea cucumber can enter the cloaked space 21 through the lower flow path 35, so that the sea cucumber can hide and sleep in the daytime. In the nighttime, the food can be safely fed to the main body (20) by eating mainly corrosive substances, microorganisms and suspended organisms in the water.
