Apparatus for advanced aquaculture life support

Claim 1

a fish farming system comprising a reservoir and a floating apparatus for cleaning biological contaminants from water in the reservoir comprising in combination: filter means positionable in the water of the reservoir, the filter means having corrugated surfaces in facing contact defining closed tubes for the support of biological agents for assisting in the cleaning and redistribution of the water in which it positioned; a frame assembly having generally horizontal tubular upper and lower frame members and generally vertical tubular intermediate frame members joining the upper and lower frame members thereby constituting a three-dimensional generally cubic shape, the tubular members adapted for receiving and supporting the filter means in the water, the tubular members being hollow and operatively interconnected for the passage of fluid therethrough and with a first opening operatively associated with an upper frame member for coupling with a source of pressurized fluid and with a second opening associated with a lower frame member; air stone means constituting a diffuser means coupled with the second opening for effecting discharge of the pressurized fluid from the source of pressurized fluid upwardly through the water and across surfaces of the filter means for cleaning of the water by the biological agent supported on the surface of the filter means; and a float ring secured with respect to the top of the frame assembly and being horizontally disposed for providing the necessary buoyancy for maintaining the upper surface of the frame assembly adjacent to the surface of the water and with the lower surface of the frame assembly spaced from the bottom of the reservoir.
