February 27, 2026 — The Trump administration’s move this month to allow commercial fishing in the Northeast Canyons and Seamounts Marine National Monument, 130 miles off Cape Cod, was welcomed by commercial fishing interests last week.
The monument’s creation was a recent development, established by President Barack Obama in the last months of his administration in 2016, with a multiyear phaseout allowed only for American lobster and Atlantic deep-sea red crab fisheries. The area in question covers nearly 5,000 square miles and includes three underwater canyons and four underwater mountains, or seamounts. In 2020, during his first term, Mr. Trump lifted the ban on commercial fishing there, but President Joseph Biden restored it the following year.
“Because of the complex topography and oceanography within the monument, and the resulting high food production, there is a rich diversity of fishes” there, according to the U.S. Fish and Wildlife Service, which manages the site with the National Oceanic and Atmospheric Administration. “Scientists consider the monument a biodiversity hotspot for deep-sea fishes.” Fish and Wildlife cites a 2003 study that found almost 600 fish species living below 650 feet in the New England shelf region of the monument.
Its canyons are home to various species of flounder, hake, skate, ocean pout, cusk, grenadier, and eel, some occurring in dense aggregations. “Larger pelagic fish like swordfish, tuna, and sharks also use the monument,” according to Fish and Wildlife.
