Threatened Species Status for Pearl Darter; Proposed rule.

We, the U.S. Fish and Wildlife Service (Service), propose to list the Pearl darter (Percina aurora), a fish from Mississippi, as a threatened species under the Endangered Species Act (Act). If we finalize this rule as proposed, it would extend the Act's protections to this species. The effect of this proposed regulation will be to add this species to the List of Endangered and Threatened Wildlife.
