It is probably not surprising to the watcher of the Deadliest Catch that fisherman have the second most dangerous occupation in the United States. Half of fishing industry deaths are caused from boats capsizing in storms or sinking from hull damage, according the National Institute for Occupational Safety and Health.
In the past, the risks associated with fishing were made worse because boats tried to maximize the amount of fish they catch before a cap for the season was reached. The government has since instituted an individual quota system for many fisheries, allowing boats to fill their assigned catch any time during the season. As a result, crabbers no longer have to venture out in foul weather or work all night to beat others in a competition.
