Abstract

PROBLEM TO BE SOLVED: To provide a method capable of multiplying corals by a simple and reliable method. SOLUTION: This is a method of multiplying corals 3, in which iron or a material containing iron is hammered into the seabed 1 or is adhered or weighted with a stone or the like and fixed. Specifically, as the iron or iron-containing material, nails, male screws, bolts, reinforcing bars, iron piles or iron wire nets are used and driven into the seabed 1 or screwed or bonded to rocks or bedrock of the seabed 1. Fix with stones or stones or rocks. If the coral 3 is easily attracted by exposing the iron part of the above material, the coral 3 can surely propagate. To expose the iron part, grind it with a grinder, scratch it with a blade, or make a score with a gold saw. It is also possible to construct artificial fishing reefs by submerging an iron three-dimensional structure on the seabed. [Selection diagram] Figure 1

Description

The present invention relates to a method for multiplying corals by a simple and reliable method.

As a conventional coral breeding method, a young coral artificially grown by IKES or the like was fixed to a rock on the seabed and transplanted, and the young coral after the transplant was grown to expect formation of a coral reef. Therefore, the conventional coral breeding method requires a great deal of cost, such as raising young corals and transporting the raised young corals to the transplantation site as they are. Also, transplanted corals often die.

On the other hand, as in Patent Document 1, in order to develop a fish reef suitable for coral reef sea areas and having a high effect of increasing fish production, it is an artificial fishing reef suitable for coral reef sea areas, such as a planar opening or the inside that forms a three-dimensional structure. Discloses a structure in which a net made of steel, resin, or chemical fiber is provided, and a reef-building coral is identified in this net by a wire or the like to be a part of an artificial fishing reef.

However, although a configuration using a steel net as disclosed in Patent Document 1 is disclosed, there is no description that corals can be propagated using this steel net. Probably because even if it is made of steel, it is galvanized or stainless steel is used to prevent it from rusting in seawater.

INDUSTRIAL APPLICABILITY The present invention focuses on the natural formation of small-scale coral reefs on many rebars driven into the seabed used for the purpose of fixing nets etc. seeded with Mozuku in the seabed in the seabed mozuku culture. It has been developed. There is a function of attracting some coral eggs and larvae to iron (Fe), which is the material of the reinforcing bar, because it is a coincidence that almost no coral can be confirmed in the rocks around the small coral reef formed in this reinforcing bar. I'm guessing.
The technical problem of the present invention is to pay attention to such a problem, and when an iron material such as a reinforcing bar is driven into the seabed and fixed to the seabed, the coral can be attracted and proliferate.

The technical problem of the present invention is solved by the following means.
According to claim 1, iron or a material containing iron is prepared, and at least a part of the surface of the main body is subjected to a processing for exposing the iron portion, and the material is driven into the seabed or is adhered or heavy with a stone or the like. It is a coral breeding method, characterized in that the coral is attracted by the surface having the iron portion exposed, and the coral is directly attached to the raw material .

Claim 2 uses a nail, a male screw, a bolt, a reinforcing bar, an iron pile, or an iron wire mesh as the iron or iron-containing material, and sinks or drives into the seabed, or screws or bonds to rocks or bedrock on the seabed. The method for multiplying coral according to claim 1, wherein the method is to fix the weight by fixing it with a stone or a stone or a rock.

As in claim 1, since iron or a material containing iron is driven into the seabed or is fixed or fixed by weighting with stones or rocks, the material is not washed away and stays at a certain position, and The coral eggs and larvae are attracted by the ingredients of, and the corals multiply and become coral reefs. Moreover, the coral breeding method of the present invention does not require a complicated process as in the past. Further, as in claim 1, since the coral is easily attracted by exposing the iron part by polishing or scratching the material, fertilized eggs and larvae of the coral are attracted to the exposed iron part, and reliably and effectively. Are attracted to and multiply.

As in claim 2 , as the iron or iron-containing material, nails, male screws, bolts, reinforcing bars, iron piles or iron wire nets are used to sink or drive into the seabed or screw into rocks or bedrock of the seabed. Since it is fixed with glue or glue or with a weight such as stones or rocks, it can be easily realized with ordinary commercial products, and can be reliably realized at low cost.

It is a front view showing the 1st example of the coral breeding method by the present invention. It is a front view which shows the 2nd Example of the coral propagation method by this invention. It is a front view which shows the 3rd Example of the coral propagation method by this invention. It is a front view which shows the 4th Example of the coral propagation method by this invention.

Next, an embodiment will be described as to how the method for multiplying corals according to the present invention is actually embodied. FIG. 1 is a front view showing a first embodiment of a coral breeding method according to the present invention. As shown in FIG. 1, nails, reinforcing bars, iron bars 2 such as iron piles are driven into the seabed 1 and fixed. The upper end 2e of the iron rod 2 has an exposed iron portion during cutting and polishing. Over time, coral eggs and larvae are attracted to the iron portion and grow, and as shown in FIG. 1, a large number of corals 3... Are grown on the upper end 2e of the iron rod 2.

Although FIG. 1 is an example, as shown in FIG. 2, when the cut portion of the upper end 3e of the iron rod 2 fixed to the seabed 1 is exposed and the side surface 2s near the upper end is ground by a grinder or the like to expose the coral, Eggs and larvae are attracted to grow and become corals 3 and 3. When the side surface of the iron rod 3 is polished or ground, or the iron portion is exposed by selecting a location with an iron saw or chisel and scratching it, the coral 3... Attaches to the desired side surface 2s of the iron rod 2 and grows. .

When the side surface of the iron rod 3 is scratched at a plurality of locations to expose the iron portion, the corals 3... Can be attached and grown at a plurality of locations on the side surface 2s of the iron rod 2 as shown in FIG. Therefore, by selecting the place where the coral 3 on the side surface 2s of the iron bar 2 attaches and grows to control the place where the coral attaches and grows, it is beautifully finished. it can. In addition, the coral in the vicinity may adhere to and grow on the side surface 2s of the iron rod 2.

As an iron material fixed to the seabed, there is also a method of fixing iron powder or shavings generated by cutting or cutting iron to cement or gypsum and hardening the mixture to the seabed. Especially in iron powder and shavings, the iron part is well exposed like the cut surface of the reinforcing bar, so it is easy to attract coral. The same effect can be expected if iron powder or shavings are kneaded into an adhesive agent and directly adhered to rocks on the seabed to be hardened and fixed.

Coral spawns on a full moon night every May to June, but it is also possible to float an iron wire net near the surface of the sea so that fertilized eggs and larvae are attracted to the iron and sink it to the seabed after a while. Is. In order to float the wire net on the surface of the sea, a floating body made of styrofoam or a floating body may be tied up and separated at the time of sinking to the sea bottom, so that a coral colony can be formed and the coral colony that has died due to the whitening phenomenon can be expected to be regenerated. In order to expose the iron part, it is preferable that the wire mesh is scratched on the concrete surface by dragging both the front side and the back side.

As described above, iron material or iron-containing material is placed in the aquarium pumping seawater or the aquarium breeding coral in the area where coral eggs and larvae are likely to live, and coral is added to the iron component. Since it attracts and attaches and grows, corals can be easily and surely propagated, and it can be used for ornamental purposes without collecting natural corals, which are originally prohibited by law.
