North Atlantic Swordfish (Xiphias gladius)
U.S. North Atlantic swordfish population levels are high and overfishing is not currently occurring on the stock.
Strict federal fisheries management measures are improving the condition of the fishery, and a fishing industry/NOAA partnership is successfully reducing sea turtle bycatch.
Swordfish is an excellent source of selenium, niacin, and vitamin B12 and a good source of zinc. Swordfish may contain amounts of methylmercury in excess of the FDA's recommended limit for moms, moms-to-be, and young children. For more information, see EPA and FDA advice on what you need to know about mercury in fish and shellfish.
About 33% percent of the swordfish caught in U.S. commercial fisheries in 2008 came from the Atlantic and Gulf of Mexico; the rest was Pacific swordfish, where population levels are also high. The United States also imports swordfish, mainly from Canada, Singapore, Panama, and Ecuador.
