Usually, each state has its own rules for how to catch crabs. For example, in Alabama, you need a saltwater fishing license, even for recreational crabbing.
In essence, you only need five things – a bucket, dip net, bait, crab gauge, gloves, and a line. Depending on your state’s regulations, you can also get crap pots.
Some of the best places to find crabs are around the water’s edge, especially in shallow water. You should also consider crabbing along the shore of an inlet, a river, or a canal.
The best length would be about 12 feet. If not on a rocky shore, a 10 feet line be enough. Tie one end of the line with a stick and the other end with your preferred bait.
Choose a spot on the water and throw your bait. Ensure your throw is strong enough to place the bait into the water far enough.
