The beam can vary in length from 2-12m. A chain mat may be fitted to the beam to increase seabed disturbance. The net is towed on the seabed and the resulting disturbance causes fish and shellfish to swim up and get caught in the net."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL0651" ; skos:note "accepted"@en ; skos:prefLabel "Unknown beam trawl"@en . skos:narrower . skos:narrower . skos:narrower .
