PROBLEM TO BE SOLVED: 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, the 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 the 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.【課題】生け簀の上部枠体に浮力により上向きの力を生じさせると共に、或いは生け簀の上部枠体の浮力及び生け簀の上部枠体の中心部に必要に応じて配置した上部中央安定体に浮力により上向きの力を生じさせると共に、下部枠体の中心部の下方に配置した下部中央安定用錘による下向きの力を生じさせて、生け簀の昇降時に生け簀が傾くのを防止することのできる浮沈式生け簀を提供することにある。【解決手段】上部枠体２及び下部枠体３とネット４が取り付けられ、環状の上部枠体２の内部を複数に仕切り浮力調整室２１をそれぞれ設け、上部枠体の環状中心部に上部中央安定体５を配置し、下部枠体３の環状中心部に下部中央安定用錘６を配置した。【選択図】 図３
