点がある。The surface type floating reef has the advantage that it is easy to confirm its position because it floats on the sea surface, that it is less likely to catch fishing line and drift net, and that it can be manufactured at low cost and has a large gathering effect. However, since the mooring line is strongly affected by the wave force, the mooring line is repeatedly subjected to excessive tension and is likely to be cut, and has a drawback that its service life is short, about one year.

欠点がある。[0004] The middle type floating fishing reef is less affected by the wave force and the tension applied to the mooring line is almost constant, so that the mooring line is hard to be cut, has excellent durability, and has an advantage of a large gathering effect. However, there is a risk that fishing lines and drift nets may be caught by the sea, which cannot be seen directly from the sea.
However, this method has the drawback that it is easy to misidentify the position.In addition, a radio transmitter such as an underwater pinger is attached to check the position using a received signal. However, there is a disadvantage that the production cost is high.
