Oyster farming is an aquaculture (or mariculture) practice in which oysters are bred and raised mainly for their pearls, shells and inner organ tissue, which is eaten. Oyster farming was practiced by the ancient Romans as early as the 1st century BC on the Italian peninsula[1][2] and later in Britain for export to Rome. The French oyster industry has relied on aquacultured oysters since the late 18th century.[3]
