Abstract: A system for cultivating a large quantity of oysters is disclosed herein. The system includes a device that can be placed either on the seabed or the surface of a water environment. The device may be placed at either location and may also be placed further offshore and still be safe from extreme weather conditions. As a result, the benefits of each location are implemented into the system. The system includes an oyster cultivating device including a rectangular frame holding various crates with multiple internal baffles or dividers, and an attached buoyant member for keeping the cultivating frame at or near the surface of the water. The crates are placed such that they fill the volume within the rectangular frame. A buoyant member is then placed on the top end of the rectangular frame. The system provides increased agitation capabilities for oysters to provide a larger and rounder cultivated oyster.
