We, the National Marine Fisheries Service (NMFS), issue a final determination to retain the threatened listing for the Oregon Coast (OC) Evolutionarily Significant Unit (ESU) of coho salmon (Oncorhynchus kisutch) under the Endangered Species Act (ESA). This listing determination will supersede our February 11, 2008, listing determination for this ESU. Our February 11, 2008, determinations establishing protective regulations under ESA section 4(d) and designating critical habitat for this ESU remain in effect.
