Open Water Systems Ltd. has spent the last 5 years designing,testing and patenting a 50′ X 50′ X 36′ 2500 cubic meter steel submersible cage for the aquaculture industry. The new cage, designed by a fish farmer with 12 years experience, was carefully planned to provide a reliable rugged rearing unit that was both fish and farmer friendly. The cage can be operated at surface in the same fashion as traditional surface cages allowing purse seine harvesting, stock inventory and inspection
WITHOUT the need of diving. The cube design allows the entire net to be secured from top to bottom providing a consistant rearing volume in high current and when towing. The upper hinged walkway is repeated at the base of the four 36′ deep spars allowing the continuous netting attachment points. The rubber insert torsion hinge design absorbs any movements between the spars and walkways minimizing metal fatigue. The lack of horizontal plannes
allows wave energy to pass through the structure minimizing the forces on the structure.

Other advantages include:
1.) A bouyancy control system that allows a fully controlled ascend and descend through the water column. The cage can be suspended at any depth in the water column in any depth of water.
2.) Top portion of cage can be raised 14′ to allow net inspection and cleaning.
3.) Cage cube allows various net designs and configurations.
4.) Capable of larger rearing volumes at reduced cost/cubic meter.
5.) Full scale open water tested in 5 meter seas.
Open Water Systems Ltd. is currently seeking companies or individuals that are interested in using this cage in real production conditions. The cage can be seen at www.openwatersystems.com. We can be contacted @ 705 377 4044 or by email @ jefftuerk@hotmail.com. The full size cage can be dismantled and container shipped worldwide.
