North American Green Sturgeon (Acipenser medirostris)
NOAA Fisheries received a petition in June 2001 from several environmental organizations requesting that the agency list the north American green sturgeon (Acipenser medirostris) under the Endangered Species Act (ESA). This population is under the jurisdiction of the NOAA Fisheries Southwest Region, and most of the information about it links to the SWR green sturgeon website.
Endangered Species Act Listing
On Apr. 7, 2006, NOAA Fisheries listed the southern distinct population segment, or DPS, of north American green sturgeon as threatened under the ESA.
On Oct. 9, 2009, NOAA Fisheries designated final ESA critical habitat for the southern distinct population segment of north American green sturgeon.
On June 2, 2010, NOAA Fisheries published final ESA protective regulations (ESA 4(d) rule) for the southern distinct population segment of North American green sturgeon, and released a final environmental assessment analyzing the environmental impacts of these ESA Section 4(d) rules.
