Traps are baited or nonbaited stationary devices set on the bottom or, less frequently, in midwater. Fish enter the trap freely but fond it diggicult to exit them. Large traps are more common in coastal waters while smaller traps may be deployed to greater depths. Fyke nets and stow nets are fixed to the bottom and rely on currents to bring fish into contact with them. Additionally, fyke nets use "wings" to guide the fish into mesh bags, where they are captured. Both types are most commonly set near shore. Barriers, weirs, fences and corrals are used in tidal areas and span the entirety of the water column. Fish enter through a narrow opening and are then trapped in a holding compartment.
