In 2001, the National Marine Fisheries Service (NMFS) received a petition requesting Endangered Species Act (ESA) listing of North American green sturgeon (Acipenser medirostris ) as a threatened or endangered species. Links to the ESA status review can be found on the Research Related to the Endangered Species Act webpage on the Fisheries Ecology Division website of the SWFSC.
