Claim:
An aquaculture system comprising: at least one aquaculture holding tank; at least one oxygenation apparatus operationally coupleable to said at least one aquaculture holding tank; at least one filter apparatus operationally coupleable to said at least one aquaculture holding tank; wherein said at least one aquaculture holding tank further comprises a plurality of aquaculture holding tanks, said plurality comprising an even number of aquaculture holding tanks deployed in a 2 by N array, wherein N is the number of aquaculture holding tanks comprising the plurality of aquaculture holding tanks divided by 2; wherein each one of said plurality of aquaculture holding tanks further comprises: a first drain member operationally coupled between an interior of said at least one aquaculture holding tank and said at least one filter apparatus; a second drain member positioned adjacent and below said first drain member, said second drain member having a conical intake section; wherein said first drain member of at least one aquaculture holding tank is environmentally coupled to a switch valve, said switch valve selectively routing an output of said first drain member to said at least one filter apparatus, said switch valve selectively routing an output of said first drain member to a purge system; wherein said switch valve comprises: a first vertical channel environmentally coupleable to said at least one filter apparatus; a first tube member selectively positionable within at least a position of said first vertical channel, said first tube member substantially closing said first vertical channel when positioned within at least a portion of said first vertical channel; a second vertical channel environmentally coupleable to said purge system; and a second tube member selectively positionable within at least a position of said second vertical channel, said second tube member substantially closing said second vertical channel when positioned within at least a portion of said second vertical channel.
