Episode Details

A family with a surname literally meaning "mussel man" discovers their Florida lagoon needs restoration—and mussels might be the answer. Exploring nine thousand years of indigenous harvesting, industrial mining's devastation, and the surprising biology of freshwater bivalves, this episode asks whether bringing mussels back is even possible.
