In Bronx River, Helping Oysters Stage Comeback

During the 1970s, the overfished and polluted Bronx River didn't support much life. However, small reefs of oysters survived, a remnant of the once millions of oysters in New York harbor. Now, 40 years later, non-profit groups are relocating farm raised oysters and dumping them in the Bronx River. A one-ace reef has already been established in the river off of Soundview Park. These oysters are not meant for eating or pearls: they are meant for a natural filtration fro the river and its reef would hopefully restore the Bronx River to its natural state.
