ABSTRACT:
The invention generally provides an apparatus that aerates the aquatic environment and agitates the bottom of the aquatic environment. One aspect of the invention provides a variable buoyancy aerator which cycles between an agitation mode and an aeration mode. Another aspect of the invention provides a system for maintaining an aqua-culture environment including one or more variable buoyancy aerators, a power source connected to supply power to activate the aerators and a controller connected to the power source to regulate activation of each aerator. The invention also provides a method for maintaining an aqua-culture environment including positioning one or more variable buoyancy aerators within the aqua-culture environment and regulating activation of each aerator to provide aeration, bottom agitation and controlled circulation to the aquatic environment.
