Bottom trawling is trawling (towing a trawl, which is a fishing net) along the seafloor. It is also referred to as "dragging". The scientific community divides bottom trawling into benthic trawling and demersal trawling. Benthic trawling is towing a net at the very bottom of the ocean and demersal trawling is towing a net just above the benthic ...
Trawling – is fishing with a large bag-like net, called a trawl, which is drawn along behind a boat called a trawler. The net can be dragged along the sea bottom in order to target demersal fish, or pulled through clear water in order to target pelagic fish. Trawling along the sea bottom can result in significant bycatch and habitat destruction.
The benthic region of the ocean begins at the shore line (intertidal or littoral zone) and extends downward along the surface of the continental shelf out to sea.Thus, the region incorporates a great variety of physical conditions differing in: depth, light penetration and pressure. [5]
Published research has shown that benthic trawling destroys the cold-water coral Lophelia pertusa, an important habitat for many deep-sea organisms. [18] Midwater (pelagic) trawling is a much "cleaner" method of fishing, in that the catch usually consists of just one species and does not physically damage the sea bottom. However, environmental ...

benthic Bottom-dwelling, living on the sea bed. benthopelagic Pertaining to fishes that swim just above the seabed at depths below about 200 m (the edge of the continental shelf). bicuspid Having two cusps or points. bifid Cleft in two. bifurcate Forked, or divided into two parts or branches. branchial Pertaining to the gills. branchial aperture
Bottom trawling is scientifically divided into two types of trawling, demersal trawling and benthic trawling, [10] which allows trawlers to target species that live close to the seabed, or those that live on or in the seabed respectively. [7]
