Demersal otter trawls - A type of bottom trawl that has two rectangular 'doors' or 'otterboards' to keep the mouth of the funnel-shaped net open horizontally while the net is being towed. A vertical opening is maintained by weights on the bottom and floats on the top. The lower edge of the net opening is dragged along the seabed with the aid of bobbins, rollers and ‘rockhoppers’, which can roll across or dig into the bottom, or bounce over obstacles.
