Abstract

PROBLEM TO BE SOLVED: To establish a method for transplanting a variety of coral communities for each of a whole community by a human-powered operation using neither a large carrying vessel, such as a salvage barge and a tugboat, nor a heavy machine.SOLUTION: The transplanting method is for transplanting a collected coral community 2 only by collecting a coral colony in a collection origin as the whole of a coral community, transporting it to a transplanting destination in a condition of being put on a bottom plate 3 of a basket B for transplantation, and lowering the basket B for transplantation to the bottom of sea with the bottom plate 3 removed. Without using an adhesive or the like after the transplantation, a natural fixation to the base is achieved utilizing a characteristic that coral colonies support each other, a fusion characteristic of a coral colony, a characteristic of taking a root to a base, a characteristic that a lower part of a coral colony is buried and stabilized at the bottom of sea, and the like.

Description

The present invention relates to a method for transplanting coral communities living on the seabed to other locations along with coral communities.

In recent years, coral reefs have been depleted due to the bleaching phenomenon caused by rising seawater temperature, damage caused by sea urchins, land development, etc., and coral reefs need to be preserved and regenerated. For this reason, coral transplantation is being promoted for the purpose of nature restoration and conservation. Currently, patents relating to coral transplantation are divided into Patent Documents 1 to 10 for the purpose of transplanting coral colonies, and Patent Document 11 to Patent Document 14 transplanting together the rocks on which coral colonies grow.

In Patent Documents 1 to 10 described above, since coral colonies are transplanted one by one, it is practically difficult to transplant coral communities on a large scale because it requires time and cost. In addition, since Patent Documents 11 to 14 are methods for transplanting the entire basement such as bedrock, heavy machinery and large transport vessels (base boats, tugboats) are required, which is costly and increases turbidity in the surrounding waters, coral reefs There are problems such as the inability to transplant many branch coral communities. Therefore, with the current coral transplantation method, there is no method for transplanting various coral communities, including coral communities that do not adhere to the base, as well as large groups, and large-scale transplantation can be performed relatively easily without using heavy machinery and large ships. The problem is that there is no way.
The technical problem of the present invention is to pay attention to such problems, and use various man-made coral communities, including coral communities that do not have habitats, by manpower, without using heavy machinery or large transport vessels (trucks, tugs). The goal is to realize a transplantable method for each community.

The first aspect of the present invention is to collect a coral community as a source of collection, transport it to a transplant destination in a state of being placed on a bottom plate of a transplantation cage, remove the bottom plate of the transplantation cage, and transplant the collected coral community Is the method.
After transplanting, without using adhesives, etc., natural coral colonies support each other, coral colony fusion characteristics, characteristics to settle on the base, coral colony submerged in the seabed and stable, etc. It is intended to adhere to.

According to a second aspect of the present invention, there is provided the coral community transplanting method according to the first aspect of the present invention, wherein the coral colony is transported in a state of being submerged in the sea so that the coral colony does not come into contact with air. Therefore, it is necessary to increase the weight of the transplantation ridge so that it sinks in the sea, to add weight, or to devise so that the transplantation ridge will sink into the sea with the weight of the collected coral colony.

[Claim 3] A coral transplantation kite which is suspended in a float, a kite or a boat and is transferred in a state of being submerged in the sea, and has a structure in which the bottom plate is pulled out sideways. It is a jar. Note that the bottom plate can be removed by a method other than the method of pulling out horizontally.

As in claim 1, the coral communities from which they are collected are collected together with the coral communities, and are transported to the transplant destination by a small ship or human power in a state where they are placed on the bottom plate of the transplantation paddle. Various coral communities, including coral communities that do not have heavy habitats, can be transplanted without using heavy machinery. In addition, the bottom plate of the transplantation jar is removed and the collected coral communities are transplanted all at once, so that it can be transplanted easily without using an adhesive or the like.

According to the second aspect, since the transplanting jar is transferred in the state of being submerged in the sea so that the coral colonies do not contact with the air, the coral colonies can be prevented from being weakened by contacting with the air.

According to the transplantation kite of claim 3, since the transplantation kite is suspended in a float, a kite or a boat and transferred in a state of being submerged in the sea, not only can the coral colony be prevented from being weakened by contact with air, Since the bottom plate is pulled out sideways, many coral colonies can be transplanted at once, the effects of turbidity can be suppressed as much as possible, and stress on the coral colonies can be reduced. Moreover, transplantation can be easily carried out by using the natural characteristics of the coral colony, etc., without using an adhesive or the like, and encouraging survival.

It is a perspective view which shows the state currently transported in the state which suspended the transplantation cage | basket in the cage | basket and was sunk in the sea. It is a principal part perspective view of the transplantation wrinkle which shows the state which pulled out the baseplate. It is a perspective view which shows a mode that the extract | collected coral colony is mounted on the baseplate of the transplantation cage. It is a perspective view which shows the state which pulled out the baseplate of the cage | basket for transplanting and transplanted the coral colony.

Next, an embodiment will be described in detail how the coral community transplanting method according to the present invention is actually embodied. FIG. 1 is a perspective view of a transplanting cage B for transporting and transplanting coral communities. A fence 1 forming a net-like container surrounds the coral colonies 2 so as not to fall off. In addition, it has a bottom plate 3 that closes the bottom of the fence 1. A pair of U-shaped guide grooves g1 and g2 provided in the lower part of the fence 1 are arranged to face each other so that the bottom plate 3 can slide horizontally as shown in FIG. Is done. h is a handle for sliding the bottom plate 3.
The transplanting ridge B is suspended by the ridge 4 with a wire, a rope, a single pipe pipe 5 or the like and is sunk in the sea W and is transferred by the boat 6. The anchor 4 is composed of a plurality of floats f, for example, and is connected to one string of the boat 6 so as to be towed by the boat 6. It should be noted that if the transplanting rod B is suspended at the bottom of the boat 6, the boat 6 serves as a kite.

In order to transplant coral communities using this transplantation spider B, a diver collects a submarine coral colony using a chisel, hammer, chisel, etc., and the diver 7 is small as shown in FIG. Carry it into the transplanting cage B with the scissors and place it on the bottom plate 3.
It is important that the collected coral colonies do not disrupt their community structure. The structure of the coral community is maintained due to the characteristics of the coral communities that fuse together, the characteristics that the coral communities support each other, the characteristics that are established on the base, and the like. The coral transplanting method of the present invention utilizes this natural property, and the strength of the coral community can be increased by using these properties without using an underwater bond.

The transplanting dredger B containing the coral colony 2 is suspended by an air lift, a buoy, a boat 6 or dredger 4, a catamaran or the like, and is towed by the transport boat 6 while being submerged so as not to be exposed on the sea surface. . Thus, since the transplanting basket B can be transported to the transplant destination, the structure of the coral community is not destroyed, and the coral can be transported without applying a load.
If the sea current is fast or transported over a long distance, transport efficiency is improved by attaching a draining means to the front part of the transplanting cage B.
When arriving at the transplant destination, the coral community that has been transported is lowered to the seabed together with the dredger B for transplantation. Thereafter, when the bottom plate 3 of the transplantation ridge B is pulled out as shown in FIG. 2 and then the transplantation ridge B and the bottom plate 3 are pulled upward, the coral community 2 is transplanted as shown in FIG.

Depending on the location, such as where the waves are susceptible to waves or reef slopes, protection can be achieved by measures against runoff, such as covering the transplanted coral community with a biodegradable net or wire net.
At the time of transplantation, the anchor rod B for transplantation is fixed by a removable rope, wire, single pipe pipe 5 or the like 5 so that it can be lowered to the seabed, and a connecting tool such as a shackle is used for the connecting portion. The transplanting ridge B may be lowered to the seabed by adding a rope or wire or using a buoyancy body.
In order to suppress the resistance of the ocean current and reduce the stress on the coral colonies, the transplanting ridge B adopts a fence shape or a net shape that does not disturb the seawater flow. Moreover, when the flow of seawater etc. is strong, it is good to equip the front part of the transplanting ridge B with auxiliary tools, such as a streamlined draining structure. When transferring a plurality of transplantation baskets B together, streamlined draining means may be provided only at the front end of the frontmost transplantation basket, or all transplanting baskets B may be provided with draining means.
The transplanting tow B can be towed with a rope as well as connected to the left or right towing or both towings of the towing boat as shown in the figure.

As described above, the present invention is a method suitable for transplanting coral communities on a large scale. However, since it is collected by human power, the load on the coral is larger than the conventional methods using heavy machinery and large ships. The load on the surrounding environment is small, such as low turbidity and low turbidity. Therefore, it is suitable for sea areas designated as natural parks.
This is a fixing method that uses the characteristics of supporting coral colonies, their fusion characteristics, and natural survival to the base, and it saves the trouble of fixing the base of the coral to the base with an adhesive such as an underwater bond. In this way, it can be relocated while maintaining the community structure of the coral community, so it is possible to transplant in consideration of the ecosystem.
Based on these effects, it can be used for future coral reef conservation measures to transplant various coral communities and contribute to the conservation of coral reefs.
