What once-abundant San Francisco Bay oyster was wiped out by over-harvesting as well as massive silting that flowed downstream from hydraulic mining in the Sierra Nevada during the gold rush?
Hog Island Oyster
Kumamoto Oyster
Olympia Oyster

San Francisco’s native Olympia oysters disappeared due to overharvesting and pollution of San Francisco Bay during the Gold Rush era, by the 1860s native Olympia oysters (Ostrea lurida) had all but disappeared locally. But they are making a comeback! More here from Presido Trust.
