SUBMERSIBLE CAGE AND SYSTEM FOR FISH FARMING

摘要

A submersible rotatable cage for fish farming comprises a central axle, a buoyant structure positioned about the central axle, and a netting attached to the buoyant structure. An actuator can be placed in operable communicati on with at least part of the buoyant structure to facilitate rotation of the buoyant structure about the central axle while the cage is in a submerged p osition. The cage can form part of a system, which includes a net cleaning a pparatus, a tethering mechanism and sweep net, that forms the basis for unde rwater fish farming.
