“You have shad, striped bass, Atlantic sturgeon, herring. Are all coming in from the ocean. They can’t reproduce in salt water. They have to have freshwater, tidal conditions like right here on the Hudson,” said Fran Dunwell, Hudson River Estuary Coordinator for the New York State Department of Environmental Conservation.
Dunwell says many people who live and commute along the Hudson don’t realize the river itself serves as a sort-of highway for migrating fish.
