Endangered and Threatened Wildlife and Plants; Adding 10 Species to the List of Endangered and Threatened Wildlife

We, the U.S. Fish and Wildlife Service (Service), in accordance with the Endangered Species Act of 1973, as amended (Act), are amending the List of Endangered and Threatened Wildlife (List) by adding: five species of foreign sturgeon (Adriatic sturgeon (Acipenser naccarii), Chinese sturgeon (A. sinensis), European sturgeon (A. sturio), Kaluga sturgeon (Huso dauricus), and Sakhalin sturgeon (A. mikadoi)); four distinct population segments (DPSs) of scalloped hammerhead shark (Sphyrna lewini) (Central and Southwest Atlantic (Central & SW Atlantic) DPS, Eastern Atlantic DPS, Indo-West Pacific DPS, and Eastern Pacific DPS); and a nonessential experimental population of Upper Columbia River spring-run Chinook salmon (Oncorhynchus tshawytscha). These amendments are based on previously published determinations by the National Marine Fisheries Service (NMFS) of the National Oceanic and Atmospheric Administration, Department of Commerce, which has jurisdiction for these species.
