NYS DEC: New Collaborative Study Estimates Population of Hudson River Endangered Shortnose Sturgeon
The New York State Department of Environmental Conservation (DEC) announced new research that estimates the population of endangered shortnose sturgeon in the Hudson River to be nearly 70,000 individuals, likely making it the largest population of sturgeon anywhere in the world. The study was coauthored by the U.S. Geological Survey (USGS) Eastern Ecological Science Center (EESC).
"Sturgeon are among the most endangered animals in the world and New York State appreciates the partnership with USGS EESC and other academic research scientists who collaborated with DEC experts to conduct this significant study,” said DEC Commissioner Amanda Lefton. “The discovery of this massive sturgeon population in the Hudson River demonstrates the value of DEC’s Hudson and Delaware Marine Fisheries management of the migratory and resident fishes of the Hudson River estuary through numerous long-term monitoring surveys since the 1980s and highlights the success of the State’s ongoing efforts to restore species like the shortnose sturgeon.”
