PURPOSE: To provide the enclosure capable of keeping a shape in large open waters where a strong current exists by connecting a slender buoyancy member to a soft structured wall so as to be floated in upright state and providing the respective slender buoyancy members with anchors. CONSTITUTION: A columnar buoy 16 is attached to a net enclosure 14, an anchor 18 is fixed on the bottom of the sea, and the buoy 16 and the anchor 18 are linked through lock steel 22. The net enclosure 14 has a wall 26 and a bottom 28 in soft structure and since the area of the buoy crossing the surface of water is small, movement induced by waves is suppressed to a minimum so that the depth of the net enclosure can be settled at a prescribed value almost in spite of power of waves. |
