The San Leandro Oyster Beds in San Leandro, California, were the origin of the oyster industry in the U.S. state of California. During the 1890s the oyster industry thrived until it became the single most important fishery in the state. Moses Wicks is supposed to have been the first to bring seed oysters around Cape Horn and implant them in the San Leandro beds. The oyster industry in San Francisco Bay was at its height around the turn of the 20th century.
