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).

で、海の汚染も防止される。The tray (5) is hung by the tray support line (10) to the bladder (2) and is stabilized by the weight (11) so as not to be inclined by the tide or the like. The bait is regularly sprayed from the top of the boat into the cage (1) every day, and the portion that cannot be eaten by the cultured fish falls from the bottom of the cage (1) and enters the tray (5). , Gather at the lowermost end of the tray (5) by its own weight. These baits are pumped through the collecting pipe (6) by operating the pump (7), and are re-sprayed from the bait recirculation pipe (8) into the cage (1). Excess food and dung are collected in the sludge tank of the ship through the dung collection pipe (9) and processed by onshore facilities. As a result, not only can the use efficiency of the bait be improved, but also bait and feces do not fall to the seabed under the cage (1), thereby preventing pollution of the sea.
