Traps are usually baited with mackerel or sardine when the fishing boat is in the port just before going out to sea. Fishers rely on bait and the acute sense of smell of crustaceans to lure them towards the traps. The rigging used during crab fishing usually consists of individual traps fastened to a branch line, which connects them to a bottom longline. Traps are spaced at regular intervals (15 m for swimming crab traps), to prevent tangling and to eliminate competition between bait. The bottom longline is tied at both extremes to an anchor or weight, and to another line connected to a marker buoy, which serves to locate and haul the gear.
