This bill proposes an amendment to the Magnuson-Stevens Fishery Conservation and Management Act , aiming to redefine the authority over fishing regulations within marine national monuments. It explicitly states that fishing in these monuments cannot be prohibited or regulated by Presidential proclamations issued under the Antiquities Act of 1906 . This restriction applies to both future and existing proclamations that might otherwise impact fishing activities in these areas. The legislation ensures that the regulation of fishing in marine national monuments will remain under the purview of the Magnuson-Stevens Act and other relevant statutes, rather than executive orders.
