ABSTRACT:
The perforated walls of conventional fish cages become partially blocked after prolonged use and the cage of the present invention offers a relatively simple means of preventing or remedying this defect by periodically rotating the cage to expose each wall in turn for cleaning or replacement. In the embodiment of FIG. 1, the cage (8) is provided with four control devices (A-D) which can be filled with air or water (via rotation valves 18 A-D) as appropriate to effect the desired rotation. These same devices can also be used to control the buoyancy of the cage and hence the level at which it floats in the ambient water preferably just on or under the surface.
