A crab trap is a device used to catch crabs in aquatic environments. Typically made of wire mesh or plastic, these traps are designed to attract crabs using bait, such as fish or chicken. Once the crabs enter the trap, they find it difficult to escape due to its structure. Crab traps come in various designs, including collapsible traps and ring nets. They are commonly used by both commercial and recreational fishers. Proper use of crab traps is regulated in many areas to ensure sustainable crab populations and minimize environmental impact.
