Abstract: Provided is a device for flipping or rotating a floating aquatic cage to mitigate biofouling, and for farm management, such as to carry out maintenance and facilitate harvesting, particularly the style of floating cage used in farming oysters and other shellfish. The device includes a hollow frame or housing which defines a path through which the floating aquatic cage may pass, including entrance and exit openings; and one or more guide elements positioned on an inside surface of the hollow frame or housing. The one or more guide elements form an obstruction to opposing corners of the floating aquatic cage, and impart a turning force in such a manner as to rotate the floating aquatic cage.
