Fishing aids are tools used to help catch fish. NETS, rods, LURES, and bobbers are all common fishing aids. NETS are a mesh of fibers used to trap fish, rods are long poles with a line attached to the end, LURES are artificial baits used to attract fish, and bobbers are floats that indicate when a fish has taken the bait. Dropnets are also used, which are NETS that hang vertically in the water and are used to catch fish from below.
