Fish weirs in shallow estuaries water, or in small streams, may be built with 1-to-3-inch-diameter (2.5 to 7.6 cm) vertical stakes and the horizontal structure, called wattling, made of brushwork to form a rough barrier at mid-tide depth. [4] Fish weirs have been used in coastal areas by indigenous peoples in all parts of the world.
