[Problem] To provide a floating-submersible cage such that listing thereof when being raised or lowered can be prevented by generating an upward force as well as a downward force, said upward force being generated by way of the buoyancy of an upper frame of the cage or by way of both the buoyancy of the upper frame of the cage and the buoyancy of an upper central stabilizing body disposed to the center of the upper frame of the cage when necessary, and said downward force being generated by way of a lower central stabilizing weight disposed below the center of a lower frame. [Solution] An upper frame (2), a lower frame (3), and a net (4) are attached, the interior of the ring-shaped upper frame (2) is partitioned into multiple portions, each with a partitioning buoyancy calibrating chamber (21), an upper central stabilizing body (5) is disposed to the center of the ring of the upper frame, and a lower central stabilizing weight (6) is disposed to the center of the ring of the lower frame (3). |
