Northern Long-eared Bat; Northern Right Whale; Southern Bog Lemming; Mussels. In 1996, a record number of sixteen-shortnose sturgeon passed above the Holyoke Dam (Kynard 1998). 2002.

NOAA Fisheries and the U.S. Geological Survey were proud sponsors of the Atlantic and Shortnose Sturgeon 2016 Workshop, which was held at the National Conservation Training Center in Shepherdstown, West Virginia, and at the U.S. Geological Survey in … Shortnose Sturgeon. Drawing by Laszlo Meszoly, from Hartel et al.

Shortnose sturgeon are classified as anadromous, living in the estuarine reaches of most Atlantic seaboard rivers and ascending to flowing freshwater to spawn. "Earth's Endangered Creatures - Shortnose Sturgeon Facts" (Online) - Licensed article from Wikipedia: The Free Encyclopedia.

In Massachusetts, populations are mostly riverine, although estuaries and coastal areas are used during the winter months. The shortnose sturgeon was Both shortnose and Atlantic sturgeon once thrived in the Delaware River, occurring in huge numbers that far exceeded those found in the Hudson. Shortnose sturgeon are known to spawn in cycles, and estimates indicate that adults may spawn at intervals of three years. U.S.FWS Species profile about species listing status, federal register publications, recovery, critical habitat, conservation planning, petitions, and life history. The Delaware River provides critical habitat to New Jersey’s only endangered fish species – the shortnose sturgeon (Acipenser brevirostrum).It can be found throughout the Delaware River estuary, occasionally entering the nearshore ocean off Delaware Bay.

There is no estimate of the population size.

Description. During much of the 20th century, however, populations suffered major declines throughout their range from the combined effects of overfishing, pollution, and habitat loss.

The shortnose sturgeon has been an endangered species in the United States since 1967. This is considered to reflect a combined population of adult shortnose sturgeon that spawn throughout the Androscoggin/Kennebec Rivers DPS. They tend to congregate in the main river channels and only use smaller tributaries to a lesser extent.

HABITAT: The Shortnose Sturgeon is an amphidromous species, meaning that they spawn in freshwater but enter saltwater habitats during their life. The federally endangered Shortnose Sturgeon Acipenser brevirostrum was once abundant in all major coastal river systems from the Saint John River, Canada, to the St. Johns River, Florida. Some species of sturgeon are harvested for their roe, which is made into caviar. While hundreds of individuals were identified below the dam from 1993-1995, only between one and six were passed in any one of these years. It is estimated that the number of sturgeon in major basins has declined by 70% over the last century.

Recognizing that the knowledge concerning shortnose sturgeon increased during the years following the species' Endangered Species Act (ESA) listing, the National Marine Fish-eries Service (NMFS) began a status review in the late 1980s to assess whether individual shortnose sturgeon populations should be considered "distinct" for ESA purposes.
