The Service determines the pallid sturgeon (Scaphirhynchus albus) to be an endangered species under authority of the Endangered Species Act (Act) of 1973. Critical habitat is not being designated. The pallid sturgeon is a large fish known only to occur in the Missouri River, the Mississippi River downstream of the Missouri River, and the lower Yellowstone River. The species is threatened through habitat modification, apparent lack of natural reproduction, commercial harvest, and hybridization in parts of its range. This rule identifies the taxon as one in need of conservation, implements protective measures, and makes available recovery measures provided by the Act.
