Billions Of Oysters Key To Revitalize Chesapeake Bay

A hatchery at the University of Maryland is dedicated to repopulating the Chesapeake Bay with nearly a billion oysters each year.

Harvests of native oysters in the bay are less than 1 percent of what they once were. The oysters filter pollution and the decline has changed the entire ecology of the Chesapeake Bay.

Jonathan Wilson of Here & Now contributor WAMU visited the Horn Point Oyster Hatchery in Cambridge, Maryland, to find out how scientists are raising oysters and trying to revive the Chesapeake Fishery.
