Gloucester, Massachusetts, is home to one of the oldest and largest fishing communities in the United States. Generations of Sicilian immigrants have worked on the rough waters of New England since the late 1600s, but recent changes in government regulations and ocean temperatures have endangered their tradition. Young aspiring fishermen are now scarce, and the history of this once prolific community is in jeopardy. Those who have fished for cod and its relative species look to stay alive despite a gloomy future.
