Fishermen like to talk about their esprit de corps, and it is true that there is a warm camaraderie, a sense of being part of an elite brotherhood. Fishermen are like combat veterans who feel understood only by their comrades who have survived the same battles. But fishing is a constant struggle for economic survival. Each man works for shares of the catch. Anyone who can’t keep up, whether because of injury or age, is harassed out of the fishery. There are few fishermen over fifty. And because fishermen are technically self-employed and not salary earners, governments have been slow to recognize claims to social benefits for those who are out of work.
