Description

Artificial fish for shrimp {artificial fish reef for lobster}

TECHNICAL FIELD The present invention relates to artificial fish flies, and more particularly, to an artificial fish flounder for shrimp that serves as a habitat and spawning ground for shrimp.

More particularly, the present invention relates to a shrimp artificial fish that can provide a vegetation environment in accordance with the habitat characteristics of dark caves and valleys, and can be moved and installed in accordance with the habitat environment preferred by the shrimp.

The reef is the base of the undersea, and it is a place where fish gather to become a good fishing ground.

These reptiles are formed naturally, but the naturally formed reptiles are limited in their location, and a lot of aquaculture has been done in recent years. In the case of aquaculture, The fish is called artificial fish.

Artificial fish is an artificial fishery that collects various benthos and swimming animals by putting artificial facilities on the sea floor. Artificial fish is made by putting blocks, stones and old fishes on the sea floor and becoming a habitat for fisheries.

The pilot project for artificial fish in Korea was first conducted in 1971 for the purpose of increasing the production of aquatic products. Since then, the artificial fish test has been conducted for several years, and since it has a good track record, it has turned into a full-scale business and is expanding its scale every year.

The installation of artificial fish is installed with national and local budgets, and the water depth of the facility is 10 ~ 40m. The types of artificial fishes are divided according to the function, but they are divided according to the materials used in general. In addition to the cement structure, the material of the artificial fish candle is made of various materials such as balm filled with talc or earth, wood, cored bar, Cement structures are mainly used, and there are cube-shaped, cylinder-shaped, hemispherical, and assembled-type according to their shapes.

The cube is a hollow cube made of pillars of each shape with a thickness of 25 cm. One size is 2m in length, height and height. The size of the cube-shaped fish catch was small, which was 1m or 1.5m in length on one side. In 1983, the length of one side was changed to 2m in length.

Cylindrical reefs are hollow cylinders with a diameter and height of 1.8 m each. It has been in use since 1983, but it is more mobile in the sea floor than other shapes of reeds. Hemispherical reefs have been used since 1983 in the shape of a hollow half-sphere with a diameter of 2 m and a height of 1.3 m, but it is often buried in a sediment after installation.

The assembled type fishing reef is Jumbo type with the bottom side of 6.5m and 5.0m in length and 5.7m in height. It has been installed since 1984, and because it is large, it is less likely to be buried during transport or submersion compared to other shapes of reeds.

The purpose of such an artificial fish 's facility is to create new sheep growth and to establish fishing grounds. Fishing reefs can also help to inhibit the fishing of certain fisheries. In other words, it is difficult to catch small unauthorized trawler traps or trawl fishing (pulling nets), which are unrecorded fishing offshore fisheries.

The effect after the artificial fish planting was 185% in the place where the artificial fish plant was not installed since 1971 for three years. Therefore, it can be seen that the effect as a fishery field is great in addition to the utilization value in the case of utilizing the fish as the growth rate.

Various artificial fishes have been developed depending on the fish species to be cultured, for example, Patent Documents 1 to 4.

On the other hand, there are more than 90 species of shrimp inhabited near the coast of Korea. In the East Sea, there are Shrimp, Shrimp, Shrimp, Seabream and Daehe in the South Sea and the West Sea.

Chicken prawns and pearl prawns live in Jejudo area. Their characteristics are large and taste good, but their production is very low.

Chicken prawns live in the deep sea coastal reef area of the Pacific coast, and the chicken prairie living in the coast of Jeju island lives in sandy shore with reefs around.

Also, octopus habitat is a reef area, and the locus of the chicken prawn is the sandy area near the reef area, so octopus is the greatest natural enemy of the chicken prairie.

The habitat of Jeju chicken prairies living in the coast of Jeju Island is caves and valleys at the bottom of the sea floor, and they feed on benthic organisms due to eating omnivorousness.

On the other hand, in case of Jeju Island, Jeju chicken prawns are disappearing due to indiscriminate oversampling, illegal harvesting by scuba diver and destruction of habitat by construction industry such as harbor development, coastal landfill, and power plant hot water.

The present invention can provide an optimal environment for shrimp.

1 to 5, a shrimp artificial fish candle according to the present invention for providing a space for scattering and forming a shrimp, A plurality of pillars 20 are provided in the lower part of the lower surface structural member to form a cub or adult living space 10 between the members 10, This serves as a natural cave to protect the shrimp and allow the adult shrimp to provide an active space.

The surface structure member 10 is formed of a sloped plate that is inclined with respect to the ground or both ends thereof facing the ground surface. At least two or more of the sloped surfaces are spaced apart at appropriate intervals to form vegetation spaces 10s, 10b Is formed.

As shown in FIG. 5, the vegetation spaces 10s and 10b may be formed as one or two or more as shown in FIG. 1 to FIG. 4, wherein the vegetation space is divided into a plurality of It can be different.

Among the vegetation spaces 10s and 10b, the vegetation space 10s is a space where the shrimp grows, and the vegetation space 10b is a space where the adult shrimp grows.

Of course, the vegetation spaces 10s and 10b function not only in the space where the cubs and adults of the shrimp grow, but also in protecting them from enemies such as octopuses.

As described above, the vegetation spaces 10s and 10b formed by laminating a plurality of surface structural members play the same role as a cave, and the inside is kept dark, which is an environment that the shrimp likes.

The column 20 prevents the surface structure member of the lowermost one of the surface structural members from being buried in the sand or mud, and serves to fix the artificial root in the ground.

The column 20 is preferably manufactured at various heights in consideration of the environment in which the artificial fish candle is installed. That is, when the depth of the sand or mound is deep, the height of the column is made large so that the lowermost structural member is spaced apart from the ground by a predetermined distance.

The artificial fish as described above is made of reinforced concrete, so that it is not pushed or conveyed even at a high flow rate due to a large wave as the weight is increased.

Further, as shown in the drawing, the surface structural member 10 is preferably formed to be inclined downward toward both ends of the center, and the angle between the both ends and the horizon line is 0 to 60 degrees and the thickness is 10 to 40 cm desirable.

It is preferable that the surface structural members are installed such that the angle between the horizontal structural members and the horizon line is increased from the lower surface to the upper surface.

When the thickness of the surface structural member is less than 10 cm, it is difficult to fix the position because the artificial fish is light because it floats on the wave. When the surface structural member is 40 cm or more, it is too heavy to carry and install, and the material cost is too much.

When the inclination of the surface structural member 10 is out of the above range, that is, when both ends are lifted up, the sunlight from above flows into the vegetation space, and the vegetation space is bright, and the shrimp becomes reluctant, If both ends are too far down, they may be buried in the middle of the day.

In addition, a scattering net 30 in which a filling material 32 is filled in the inside of the housing 31 of the capillary or tubular shape may be additionally provided in any one of the above-mentioned habitats 10s and 10b to serve as a spawning ground for shrimp.

The housing 31 constituting the scattering net 30 is made of iron or a fiber or a rope or a PVC pipe and the filler 32 is made of a seashell, a shell, a shell, an abalone shell, a wood slice, Lt; / RTI >

In addition, it is preferable that a groove 12 is formed on the upper surface of the surface structure member provided at the uppermost one of the surface structural members 10 to widen the attachment area of seaweed spores or to install a rope with seaweeds attached thereto.

That is, as shown in FIGS. 4 and 5, a groove 12 such as a turtle or the like is formed on the upper surface of the uppermost surface structural member, and the groove may be any one of grid, circle and ellipse, It serves as a roughened surface or an uneven surface where seaweeds can easily be attached.

The space between the grooves is the passage of the sea turtles, abalone, and sea cucumbers.

It is preferable that the surface structure member provided at the uppermost one of the surface structural members further has the bending cleavage portion 11 so that both ends in the longitudinal direction are bent downward to enclose the end portion of the lower surface structural member.

As described above, the shrimp likes a dark place, and the vegetation space is covered by the surface structural members, so that the shading can be darkened, but the light shielding portion 11 is formed to lower the illuminance, .

In addition, since the artificial fish weights of the present invention are heavy, it is preferable to use a towing apparatus when transporting or installing the artificial fish weights. At this time, one or more towing rings 13 are provided at the upper portion so as to be towed by a towing apparatus.

The artificial fish candle of the present invention constructed as described above can be formed by various methods. However, it is preferable that the artificial fish candle can be made by pouring concrete after placing the artificial fish candle in the drawing at 90 ^o , When casting, it is preferable to use fluid concrete to fill the concrete densely.

After curing is completed, it is stored or installed in the correct position as shown in Figs. 1 to 5.

That is, it can be made by curing and demolding after making concrete by using steel, wood or plastic, by placing reinforcing bars in formwork, by putting concrete (usually concrete, fluid concrete or alkaline neutral special concrete) have.

The artificial fish of the present invention not only plays the role of an artificial cave but also prevents the scuba diver from overfishing.
