Depending on the capacity of the boat, a crab fishing boat typically stays in the sea for three to four weeks at a time. This time also varies depending on how long it will take to catch the fish. In the old derby style, many of the crews wanted to catch many crabs within a short time, which means a few days. The competition is high. In 2005, the system changed to the quota system. The Alaska Department of Fish and Game embraced this system. It is a system where established owners were given quotas to fill at a more relaxed pace. The value of the crabs' increases because the crabs are not available throughout the year. It also made crabbing safer for crew members.
