how do crab traps work
Pot Design. A crab pot works like any other crustacean pot, including lobster traps, prawn traps and some minnow traps. The crab pot uses a system of nets inside a large metal cage made of wire or flat metal mesh that is reinforced with steel bars.The traps or pots are designed to allow crabs in but not let them out.etting the Catch. A crab pot is a large square about 2 feet high and 8 feet wide. Two ends have lead-ins that angle into the trap from the sides and bottom to a narrow slit about 2 feet into the pot. This slit is the only entrance into the trap. The crabs realize they must crawl up the leads to get to their free meal.
