ABSTRACT:
Anchorable mobile pens for growing fish or shellfish that have an elongate central vertical spar buoy surrounded by at least one horizontal net-supporting ring with continuous netting extending from an upper end of the buoy to the ring and thence to a lower, submerged end of the buoy to produce an enclosed pen. The pen is optionally not anchored and free to float with the currents although it may more often be anchored by conventional means. The mobility of the pens provides the benefits of avoidance of localized hazards, like toxic plankton blooms, and the capability to move the pen to a more convenient fish-harvesting location, if necessary.
