The National Marine Fisheries Service is proposing to amend its regulations to implement recently passed laws against illegal, unreported and unregulated (IUU) fishing. The proposed rule would revise the regulatory definition of IUU fishing, revise regulatory penalty provisions, amend procedures for identifying and certifying nations that have vessels engaged in IUU fishing, reduce the period of validity for certain vessel permits and expand the information required to be submitted by foreign fishing vessels requesting entry into U.S. ports.
