bottom trawl
a net shaped like a bag dragged along the sea floor. The lower edge of the net has a thick ground rope or bobbins to prevent net damage and is heavily ballasted. Some trawls are low-opening to capture demersal species, others are high opening to capture semi-demersal or pelagic species
