President Donald Trump on Thursday issued a proclamation reopening large portions of several Pacific marine national monuments to commercial fishing, stating that existing federal conservation laws provide sufficient protections for marine resources while allowing economic opportunities for U.S. fishermen.
The proclamation modifies previous presidential actions that restricted commercial fishing within portions of the Papahānaumokuākea Marine National Monument near Hawaii, the Mariana Trench Marine National Monument, and the Rose Atoll Marine National Monument in the South Pacific, the White House said.
