Definition of Term

midwater trawl
(English) A net towed through the water column by one boat above the bottom and below the surface. It may have otter doors that function to keep the net mouth open and depressor plates that function to make it fish deeper, or two vessels pair trawling keep the mouth open. The front net sections are often made with very large meshes or ropes, which herd the fish schools towards the net aft sections. The fishing depth is usually controlled by means of a net sounder (netsone). (See also: midwater, midwater pair trawl, trawl)
