Oyster Culture Float provides farmers with the use of intertidal and deep-sea fields. The oyster strings can be switched between verticals and horizontals by binding or removing the rope on one side. Farmers take it for culturing or harvesting without spending manpower on tying and handling. By rotating the OCF, the strings of oysters can be pulled out of the water surface by buoyancy, and reduce the infection from the direct contact between farmers' skin and shells. OCF moves the oysters to the shore in case of serious natural disasters, to avoid serious economic impact and marine pollution.
