発生している。In the above-mentioned conventional cultured cage, a large part of the sprayed bait falls from the mesh at the bottom of the cage without being eaten by the cultured fish and shellfish, and the utilization efficiency of the bait is low. There was a problem. As a result, extra food was required, and the cost of aquaculture was high. In addition, a long-term use forms a sludge-like sedimentary layer consisting of food and dung on the seabed under the cage, but the food and dung deposited on the seabed may cause toxic gas generation and marine pollution. From becoming
There is also a problem that the living cage must be relocated to another sea area.

A recovery pipe (6), one end of which is attached to the bottom and the other end is located on the sea surface, and a pump provided at the sea-side end of the recovery pipe (6)
(7), a feed recirculation pipe (8) and a feces collection pipe (9) attached to a pump (7), and four tray support lines (4) connecting the upper surface of the tray (5) and the floating bag (2). 10) and a tray support weight (11) provided at the bottom of the tray (5).
