In the depths of the Alaskan ocean in the United States, the survival of such a crab, which is wearing red armor, the size of the strange, known as the king of the community, and has a very domineering name --- Alaskan king crab. People know that king crabs are delicious, but few know the cost of the labor, and sometimes the lives, of the Alaskan crabbers who catch them. Alaskan crabbers have one of the most dangerous jobs in the world. On average, one crabber is killed every seven days in the Bering Strait during the crabbing season. During the season, crabbers often work 21 hours a day, sometimes back-to-back. Extreme fatigue combined with the cold weather makes the fishermen's reflexes slow down and they become unsteady on the bumpy and slippery decks, and many of them are drowned when they are swept into the sea by the ferocious waves in this situation. For all the hard work and risk, the fishermen are also rewarded. During the crab season, the average crab boat catches about 20 tons of crab. In 2004, Alaskan fishing boats*** caught 6,800 tons of crab, valued at $65.8 million. This means that each fisherman can earn between $20,000 and $100,000 in five days on a fully loaded boat. That's a lot of money for fishermen who are generally not well educated. If it were not for the money, no one would want to work as a crab fisherman.
