Crab fishermen are particularly upset about the Marine National Monument. "I am a firm believer in environmental action," says John Williams, who has been trapping crabs in the Atlantic canyons since the 1990s. "But this [sanctuary] will hurt us. It's a trophy for Obama and his legacy. A trophy at my expense, and at the expense of all crab fishermen in New England." Mr Obama has said crab fisherman can operate in the canyons for another seven years, but Mr Williams believes this is a gagging tactic, intended to smother their complaints.
