DNR officials say the state is considering new rules that would require all crabbers to have a license, even dockside chicken-neckers. Researchers are trying to determine how many crabs are caught by recreational crabbers to further efforts on rebuilding the population. Licensing is being considered as one way to track the catch from an estimated 65,000 people who occasionally tap area waterways with shore-side dip nets. The permit fee could be as low as two-dollars for the casual crabber who catches no more than two dozen crabs per day. Opponents are asking officials to consider other ways to track the recreational catch without imposing fees.
