Atlantic Sturgeon
Acipenser oxyrinchus Mitchill, 1815
Ray-finned Fishes

Threats [-]
The threats to Atlantic sturgeon include dredging and other potentially harmful activities that take place in spawning and nursery areas. Ocean bycatch throughout the migratory range may also cause declines (New York State Department of Environmental Conservation 2006).

Conservation Strategies and Management Practices [-]
Restriction of fisheries that have the greatest bycatch, both spatially and temporally, are needed. The moratorium on the possession of Atlantic sturgeon should also be maintained (New York State Department of Environmental Conservation 2006).

Research Needs [-]
Recommended Atlantic sturgeon habitat research includes the following: Trawl surveys in the near-shore waters of New York, along the south shore of Long Island, should take place in order to identify juvenile and sub-adult fish concentration areas; sonic tagging and tracking of wild juveniles should take place in order to identify seasonal habitat use by juveniles within the Hudson River estuary; sonic tagging and tracking of wild adults should take place in order to identify spawning locations, as well as to determine pre-spawning and post-spawning sturgeon concentrations; and archival tags should be used to gather data on marine habitat use by adult sturgeon. Life history research should include gathering date on age and length correlation in order to calculate age estimates for juvenile fish based on their lengths (New York State Department of Environmental Conservation 2006).
