Endangered and Threatened Species; Final Endangered Status for a Distinct Population Segment of Anadromous Atlantic Salmon (Salmo salar) in the Gulf of Maine

The National Marine Fisheries Service (NMFS) and the U.S. Fish and Wildlife Service (FWS) (the Services) determine endangered status pursuant to the Endangered Species Act of 1973 (ESA), as amended, for the Gulf of Maine distinct population segment (DPS) of Atlantic salmon. A biological review team (BRT) composed of the Services' staff completed a comprehensive status review of Atlantic salmon which resulted in the proposed listing on November 17, 1999. After reviewing additional information, including information submitted during the comment period on the proposed listing, and after considering the low numbers of returning adults, the lower than anticipated parr to smolt survival, and the serious and continuing nature of threats to the species, the Services conclude that the Gulf of Maine DPS warrants protection under the ESA. The Services have determined that the Gulf of Maine DPS is in danger of extinction throughout its range.
