Shad; the largest of New York’s herring and at one time the most important commercial fish in the Hudson River. The Hudson was known as one of the most productive rivers of shad in North America. It’s latin name means “most delicious”. They are anadromous – born in freshwater, but live in the ocean and return to the river of origin to spawn. Today, their numbers are at he lowest point ever.
Pearl essence, a silvery substance extracted from the scales of herring, and other schooling fishes is one of the many fish by products used. Pearl essence is important to the manufacturing of lipstick, nail polish, paints, ceramics and costume jewelry.
The Hudson River is the largest river entirely within state borders that is home to all members of the herring family. They spend the bulk of their lives in the ocean and only return to freshwater to reproduce.
The Hudson River Estuary logo depicts an Atlantic sturgeon, the Hudson’s largest fish. It highlights the estuary’s critical role as habitat for valuable fish and wildlife and the need to be vigilant in protecting this natural heritage. Through a partnership involving the DEC, the New York State Department of Transportation, the New York State Thruway Authority, and the New York State Bridge Authority, the logo appears on signs where major highways cross tributaries of the estuary. It reminds travelers that these streams are intimately connected to the mainstream, and that the health of the Hudson depends on the health of its watershed.
