To amend the Magnuson-Stevens Fishery Conservation and Management Act to provide for the regulation of fishing in marine national monuments.

HR 8904 prevents the President from using the Antiquities Act to ban or restrict fishing within marine national monuments. Instead, the bill mandates that fishing rules in these areas must be established through the existing Magnuson-Stevens Fishery Conservation and Management Act. This change directly affects the management of marine protected areas by ensuring that fishing regulations are handled by fishery councils rather than executive proclamation.
