[Prior art and its problems] The need for marine development is widely recognized socially from the viewpoint of economic efficiency as a fishery industry, from the perspective of global resources of fostering and utilizing marine resources, and from the perspective of environment. Has been done. In fact, in the fishery industry as well, the flow has changed from the traditional fishing industry to the growing fishery, and the realization of an ocean ranch as a facility for that purpose has been seriously studied.

From such a background, attention has been paid to the growth and production of kelp as a new direction of fishery. On the other hand, kelp growth in the coastal areas of Japan has a big problem as a change in the marine environment. It is becoming apparent. The reason is that the phenomenon of rock burning is becoming more visible. Due to this rock burning phenomenon, the disorder has become a problem in the growth of kelp.

[0004] With respect to this rock burning phenomenon, the cause and a fundamental solution have not been found, but in reality, a new industry is developed by a more productive and kelp aquaculture adapted to the coastal environment. I have no choice but to go. Although artificial seaweed beds have been created for kelp aquaculture, methods such as creating rock reefs with stones and promoting seawater flow with diversion ditches have been adopted. There is.

However, these conventional methods cannot achieve dramatic development as a realistic new aquaculture method, and cannot prevent feeding damage caused by sea urchins and reproduction of other seaweeds. There was a drawback. In addition, it is also considered to form a artificial seaweed bed by setting a pile in the sea and fixing it, and spreading a kelp trunk network or trunk rope on this fixed structure. There has been a problem that the cost becomes large and the durability against the external force such as waves is poor.

EXAMPLE FIG. 1 shows an example of the middle layer seaweed bed of the present invention. For example, as illustrated in Figure 1, this
In the present invention, a plurality of kelp trunk ropes (1) are arranged so as to be substantially parallel to the coast and at right angles to the traveling direction of the waves.
Retractable mooring spar buoy (2) (hereinafter referred to as spar buoy
It has been stretched under the sea level by say). Further, in this example, a horizontal pipe (3) and a vertical pipe (4) are sequentially connected to the spar buoy (2), and a plurality of kelp trunk ropes (1) are connected to the horizontal pipe (3) and spread. is doing. The kelp trunk ropes (1) are installed at substantially equal intervals so that the kelp trunks (1) sway in substantially the same phase as the waves.

The kelp trunk rope (1) in this case is, for example, as shown in FIG.
The kelp can be constructed by winding the kelp seed rope (12) and the like, and the kelp is rooted in the trunk rope (1) and propagates. The kelp trunk line (1) may be connected to the horizontal pipe (3) by an appropriate locking means, for example, hook means, and the kelp after growth is released from this connection, and the trunk line (1) is attached onboard. ) Should be collected.

FIG. 3 shows the example of FIG. 1 as a plan view and a front view. The kelp trunk rope (1) is provided with an intermediate buoy (5) at an intermediate portion thereof at substantially equal intervals between the horizontal pipes (3) respectively connected to the plurality of spar buoys (2).
And the intermediate pipe (6) is arranged, and the kelp trunk (1)
Extend below sea level while preventing them from touching each other. There is no particular limit to the number of spar buoys (2), horizontal pipes (3), and kelp trunk ropes (1) that can be arranged in the XY direction in the figure according to the conditions of the sea area. Can be installed and expanded. The overall width is also appropriate, for example, the width (W) between the spar buoy (2) and the horizontal pipe (3) is about 50 to 150 m, and the length (L) of the horizontal pipe is 20 to 50 m. The degree can be appropriately set. The horizontal pipe (3) connected to these spar buoys (2), the weight of the kelp trunk (1), the base material, the wave force, etc. may be selected.

When installing the spring buoy (7)
Can be used as required. Super buoy (2)
FIG. 4 shows an example. For example, this Figure 4
As illustrated in FIG. 2, the spar buoy (2) is composed of a center pipe (21), a buoyant body (22), a power supply chamber (23), a lantern (24), and the like, and is attached to the seabed via a chain ring (25) and the like. The buoyancy body (2
