The pallid sturgeon (Scaphirhynchus albus) is one of the rarest and largest freshwater fish in North America. The pallid sturgeon is a Montana Species of Concern and was classified as "endangered" by the U.S. Fish and Wildlife Service in 1990.
The pallid sturgeon was listed as a federally endangered species in 1990. Because of the wide range of the pallid sturgeon, its extreme rarity, numerous threats to species survival, and the lack of information on species life history and habitats, a team was established to develop this Pallid Sturgeon Recovery Plan.
