Start by securing your bait to the end of the weighted line. Next, drop it into the water and let it sink to the bottom. The crabs will be on your bait the moment it hits the water, so secure the other end of your line to one of the sticks to prevent the crabs from running away with it. When the crab grasps the bait with its powerful claws and begins to move away with it, gently pick up the line and begin a steady hand over hand retrieval. As the crab comes into sight, slowly raise it off the bottom and swing it towards your dip net.
Crabs are a super aggressive and tenacious predator. Be very cautious when releasing the crabs into the bucket, as they are quick to lash out and they have extremely powerful claws. Make sure to instruct any children you have with you to stay clear of the claws.
If there are a lot of crabs in the area you are fishing, you should have action until your bait runs out or you reach the legal limit of 25 crabs. Remember: any blue crabs you keep must be five inches long from spike to spike and must be male (females have distinct red tips on their claws and are easy to identify, see below). Crabs will keep well in your bucket for hours as long as they are kept out of the sun.
