A dredge consists of a metal mesh bag held open by a frame. This type of gear is dragged along the seafloor to collect bottom-dwelling organism; shellfish are particularly targeted. Some dredges have teeth or rakes that penetrate the sediment and remove large infauna. Multiple dredges can be use simultaneously via a connecting beam system.
