Hudson Bay (Inuktitut: Kangiqsualuk ilua, French: baie d'Hudson) (sometimes called Hudson's Bay, usually historically) is a large body of saltwater in northeastern Canada with a surface area of 1,230,000 square kilometres (470,000 sq mi).
The Hudson estuary stretches 153 miles from Troy to New York Harbor, nearly half the river's 315 mile course between Lake Tear of the Clouds in the Adirondacks and the Battery at the tip of Manhattan.ore than 200 species of fish are found in the Hudson and its tributaries. The estuary's productivity is ecologically and economically valuable to much of the Atlantic Coast; key commercial and recreational species like striped bass, bluefish, and blue crab depend on nursery habitat here.
