50 C.F.R. § 300.200
The purpose of this subpart is to implement the requirements in the High Seas Driftnet Fishing Moratorium Protection Act ("Moratorium Protection Act") to identify and certify nations whose vessels engaged in illegal, unreported, or unregulated fishing; whose fishing activities result in bycatch of protected living marine resources; or whose vessels engaged in fishing activities or practices on the high seas that target or incidentally catch sharks where the nation has not adopted a regulatory program for the conservation of sharks, comparable in effectiveness to that of the United States, taking into account different conditions. This language applies to vessels entitled to fly the flag of the nation in question. Where the Secretary of Commerce determines that an identified nation has not taken the necessary actions to warrant receipt of a positive certification, the Secretary of Commerce may recommend to the President that the United States prohibit the importation of certain fish and fish products from the identified nation or other measures. The Secretary of Commerce will recommend to the President appropriate measures, including trade restrictive measures, to be taken against identified nations that have not received a positive certification, to address the fishing activities or practices for which such nations were identified in the biennial report. The Secretary of Commerce will make such a recommendation on a case-by-case basis in accordance with international obligations, including the World Trade Organization (WTO) Agreement. The Moratorium Protection Act also authorizes cooperation and assistance to nations to take action to combat illegal, unreported, or unregulated fishing, reduce bycatch of protected living marine resources, and achieve shark conservation.
