Prevention of Escapement of Genetically Altered Salmon in the United States Act

Prevention of Escapement of Genetically Altered Salmon in the United States Act - Prohibits a person from: (1) shipping, transporting, offering for sale, selling, or purchasing a covered fish, or a food product containing such fish, in interstate commerce; (2) having custody, control, or possession of, with the intent to ship, transport, offer for sale, sell, or purchase such fish or food products, in interstate or foreign commerce; (3) engaging in net-pen aquaculture of such fish; (4) releasing such fish into a natural environment; or (5) having custody, control, or possession of such fish with the intent to release it into a natural environment.

Defines "covered fish" as any finfish (live or dead, including the gametes, fertilized eggs, offspring, and descendants) that is modified or produced through the application of recombinant deoxyribonucleic acid (DNA) technologies, using DNA from an organism's own genome or that of another species, that overcome natural physiological reproductive barriers and that are not techniques used in traditional breeding and selection.

Exempts from such prohibitions fish, fish parts, or products confined for scientific research or collected to enforce this Act. Sets forth an additional exception if the Under Secretary of Commerce for Oceans and Atmosphere, upon reviewing any application requesting a federal agency to permit activity prohibited by this Act: (1) prepares a finding of no significant impact in accordance with the National Environmental Policy Act of 1969, or (2) finds the application to be consistent with an environmental impact statement that includes an environmental risk analysis and specified assessments of costs and potential economic damage.

Directs each federal agency to promptly notify the Under Secretary when an action involving such covered fish or food products is first identified by such agency.

Authorizes the Secretary of Commerce to enforce penalties for violations of this Act under specified provisions of the Magnuson-Stevens Fishery Conservation and Management Act.
