Abstract:
1. A pond aeration system comprising: an aquaculture pond structured to support living fish; a “u” shaped pipe, the pipe having an inlet side, an outlet side, and a base; the pipe inlet side extending from above a pond bottom to the base below the pond bottom, and the outlet side extending from the base to an outlet above the pond bottom; a sparger assembly positioned at an intersection of the outlet side and the base below the pond bottom; wherein the system is structured so that air is directed to the sparger and the sparger emits the air into the outlet side, thereby causing a hydrostatic pressure imbalance between the inlet side and the outlet side so that water circulates through the pipe, the system being structured so that the sparger emits a sufficient volume of air so that the dissolved oxygen level in at least a portion of the pond supports the living fish.
