The job of a crab fisherman involves a huge amount of risk, particularly if the weather turns foul when they venture out into the sea. On average, a crab fisherman earns in the range of $30,000 to $40,000 for a two-month season. However, their earnings may vary substantially depending upon their catch, the type of the boat they engage, and the strength of the crew. The price per pound of the catch that is determined at the dock. The crab fishermen on The Deadliest Catch make up to $100,000 or more.
