Dredge pertains to machines used mainly to target shellfish, dredges employ a heavy mesh to suck everything from the sea floor. The gear is dragged along the bottom, and the shellfish are held in a sort of bag or sieve which allows the water, sand or mud to run out.
Boat dredges are of varying weight and size but are usually fairly heavy, so impacts on bottom habitats are a concern.
