Ocean City, Maryland is known as the White Marlin Capital of the World. The city hosts the annual White Marlin Open, a big game tournament which attracts anglers from all over the world and which frequently pays out over a million dollars to the winning team. The tournament encourages tag and release (non lethal) of the fish, although winning marlins are often brought back to the marina for verification of the size and weight.
