Various attempts have been made to recover coral colonies and to grow new coral colonies from the viewpoints of protecting a beautiful natural environment in tropical sea areas, securing a place for breeding and growing marine life, and the like. These are transplantation methods in which coral pieces are directly or indirectly transplanted and adhered to a large substrate placed on the sea floor (for example, see Japanese Unexamined Patent Publication No.
No. 3,209,532, Japanese Patent Application Laid-Open No. 2-135033). In addition, as another method, a coral is attached to a shelf on a buoyant body floating on the sea surface, and the coral is fixed thereto, or a rope or the like is suspended from the buoyant body, and a coral piece is fixed to the buoyant body to proliferate. Transplanting coral to the sea floor (for example, Japanese Patent Application Laid-Open No. H11-3262).

Become. However, if corals can be grown by aquaculture, not natural corals,
It is possible to collect ornamental corals without destroying the natural environment. From such a viewpoint, a coral culturing method for obtaining corals by culturing has been proposed in, for example, the above-mentioned Japanese Patent Application Laid-Open No. 6-303875.
In that case, the obtained coral must be clearly distinguished from natural ones.

題点がある。In the case of the above-mentioned conventional transplantation method, there are many problems such as being deposited on the sea bottom and being eroded by sand and being eaten by the sea starfish. On the other hand, the hanging aquaculture method occupies the sea surface with a buoyant body on the sea surface, it can be used only on the sea surface with high calmness to prevent the buoyant body from flowing out due to typhoons, etc. That it is necessary to secure a certain depth of water or more in order to hang, it is necessary to take sufficient spacing between the hanging ropes to prevent damage to the coral that hangs due to waves, etc.
It is difficult to move between underwater and onshore breeding aquarium,
The coral has ropes and other artificial materials, which make it difficult to see in the land breeding aquarium.Furthermore, if the rope attached to the coral is removed, it is difficult to distinguish it from natural products, and the equipment becomes larger. There are problems such as high equipment costs.

It can be used, has no occupants on the sea surface, is less susceptible to typhoons, is less susceptible to sand accumulation and the damage of sea starfish, and can cultivate corals well with inexpensive facilities. It is an object of the present invention to provide a coral cultivation method and a coral cultivation method capable of obtaining corals that can be easily moved and that can be applied to ornamental use as self-cultured corals for easy distinction from natural products. is there.

The top of the joint pipe 7 is exposed in the substrate receiving member 8-1, and the substrate receiving member 8 is fixed at the top.
-1 to support the artificial substrate 1 inserted therein. Further, the substrate receiving member 8-2 of the fixing device 6-2 has a pair of cut pieces 9 formed on opposite surfaces of the substrate receiving member 8-1, and bends them inwardly by 90 °. do it,
The artificial substrate 1 is supported. The substrate receiving member 8-3 of the fixing device 6-3 has a small-diameter cylindrical portion 10 that fits into the joint pipe 7 at the lower portion, and a large-diameter cylindrical substrate receiving portion 11 at the upper portion. As shown in the figure, the cylindrical substrate receiving portion 11 has four grooves 12 formed at 90 ° intervals in the vertical direction, and receives the four corners of the artificial substrate 1 at the bottom of the grooves. As described above, three different forms of the substrate receiving member have been described. However, the substrate receiving member of the present invention is not limited to the above shape, and any shape can be used as long as the artificial substrate 1 can be detachably fitted and held. Further, in the present embodiment, the joint pipe of the fixing device 6 is fitted to the reinforcing steel pile erected on the sea floor. However, the joint pipe of the fixing device 6 is formed in a pile shape, and the fixing device 6 is directly connected to the sea floor. And may be installed upright.

It grows naturally attached to artificial substrates. In particular, in the present invention,
Since it is a culture that is made by attaching coral pieces to an artificial substrate that is formed small and can be easily moved, it can be freely moved between a breeding aquarium installed on land and an underwater fixing device installed in the sea, for example After cultivation in the sea for a predetermined period of time, when the plants have grown, they can be transferred to a land breeding aquarium and displayed for cultivation. In addition, since aquaculture in the sea is installed on the substrate receiver provided at the top of the pile, it is located above the sea floor, so it may be affected by the sea starling moving on the sea bottom and red soil etc. It can grow well without it. In addition, unlike the conventional hanging coral culture, a buoyant body is not installed on the sea surface to occupy the sea surface, and is not easily affected by waves. In addition, aquaculture can be performed in shallow waters and sandy areas.

Can be In commercialization, the commercial value can be further enhanced by appropriately selecting the shape and material of the artificial substrate. In addition, if the corals cultured as described above are fixed and grown on the seabed together with the artificial substrate, a beautiful coral colony can be formed in the sea, which can enhance the underwater landscape and improve the marine life. Can provide environment.

徴を有している。FIG. 5 shows another embodiment of the coral cultivation apparatus of the present invention. In this embodiment, the form of the artificial substrate is the same as that of the above embodiment, but the structure of the underwater fixing device that supports the artificial substrate in the sea is different. In the above-described embodiment, the artificial substrate is held for each pile erected in the sea, but in the present embodiment, a shelf supported by the pile is provided in the sea, and a plurality of artificial substrates are provided on the shelf. I try to hold. In the figure, reference numeral 20 denotes an underwater fixing device, which has a frame body 24 provided with a receiving member such as an appropriate mesh net 23 on a lower surface of a lattice frame 22 having a size larger than at least the artificial substrate 1 as shown in the drawing. , Legs (pile) provided at four corners 2
1 and supported. Therefore, in this embodiment, since the entire underwater fixing device is assembled on land and merely installed on the seabed, the operation is very simple. In that case, the upper surface of the artificial substrate 1 is at least 30 cm from the sea bottom.
By arranging them so as to be located at a distance as described above, it is possible to prevent the corals in the culture from being damaged by the sea starfish, red soil, sand, and the like. Although the underwater fixing device 26 shown in FIG. 6 shows an example in which the grid of the frame in the underwater fixing device shown in FIG. 5 is enlarged, the shape of the frame is not limited to these. As described above, this embodiment also has a feature that the artificial substrate can be detachably set to the underwater fixing device installed on the sea floor.

とができる。As described above, according to the present invention, it is possible to effectively utilize a shallow sea area where a buoyant body cannot be installed or a sandy area which has been regarded as unsuitable for coral cultivation. Less susceptible to typhoons and the like, and less susceptible to sedimentation of sand and starfish, enabling good cultivation of corals, easy movement of corals, and easy differentiation from natural products As for self-cultured corals, corals that can be applied for ornamental use can be obtained. In addition, the aquaculture equipment does not require a large-sized equipment, can be inexpensive, and requires less work in the sea, making the work easier. In addition, the cultured corals can contribute to the growth of coral colonies by a relatively simple method by transplanting them to the seabed.
