1. Relevant studies show that Alaska crabbers are engaged in the most dangerous occupation in the world. Their work-related injury mortality rate is 50 times that of ordinary workers. During the crabbing season, an average of one crabber dies every seven days in the Bering Strait.

2. Because the fishing time for king crab is limited, usually from October to November every year, the seawater temperature in this season is very low, which is not conducive to fishing.

3. Secondly, because they have to catch king crabs continuously for a long time, the workers' physical strength is easily exhausted. After catching the king crabs, they may not have the strength to return to the boat and lose their lives.
