How did the United States get to where it is today with sustainable fisheries? Through 40 years of the Magnuson-Stevens Act. U.S. fisheries include more than 470 fish stocks and stock complexes and are globally recognized as responsibly managed. Through a system of regional fisheries management councils, NOAA works with fishermen and partners to accomplish sustainable management of U.S. fisheries, which contribute over $100 billion each year to the U.S. economy and supports 1.8 million jobs.
