June 4, 2026 — A bill being considered in U.S. Congress would prohibit presidents from prohibiting commercial fishing in marine national monuments, codifying that fishing activities in those areas must be regulated under the Magnuson-Stevens Act (MSA).
Successive presidents’ administrations have used the Antiquities Act to unilaterally establish national marine monuments or to change the protections granted within them, and commercial fishing groups have long bemoaned the use of that power to ban fishing within their boundaries. Former U.S. President Barack Obama prohibited commercial fishing within the nearly 5,000-square-mile Northeast Canyons and Seamounts Marine National Monument when he established it in 2016, and later presidents have alternated between reallowing commercial fishing or banning it again; most recently, U.S. President Donald Trump issued an executive order reauthorizing commercial fishing in the marine national monument.
