Endangered species: experimental populations: Chinook salmon.

The federal Endangered Species Act of 1973 (FESA) directs federal agencies, in consultation with the Secretary of the Interior or the Secretary of Commerce, as appropriate, to carry out conservation programs for endangered species listed under FESA. FESA generally prohibits activities affecting these threatened and endangered species unless authorized by a permit from the United States Fish and Wildlife Service or the National Marine Fisheries Service, as appropriate. FESA provides for enhancement of survival permits to allow actions necessary for the establishment and maintenance of experimental populations designated pursuant to that act.
