Atlantic Sturgeon
Acipenser oxyrinchus Mitchill, 1815
Ray-finned Fishes

Habitat [-]
During spawning, the Atlantic sturgeon can be found in the freshwater and brackish/salt water regions of the Hudson River north to Albany, but the species is usually confined to the deeper parts of the river. The adults spend most of their time at sea and the juveniles spend the first few years of their lives in freshwater streams.

Associated Ecological Communities [-]
  • Tidal river
    The aquatic community of a river under the influence of daily lunar tides. We restrict this community to the continuously flooded portions of the river where plants do not grow out of the water. A deepwater zone has depths averaging more than 2 m (6 ft) at low tide. Salinities at any one place in the river may fluctuate as the tides flow in and out.

Associated Species [-]
  • Shortnose Sturgeon (Acipenser brevirostrum)
