The funnel shaped trawl nets are hauled by one or two boats. This method is generally used to catch fishes of a single species. Unlike bottom trawling, this type of trawl does not come into contact with the sea bed and hence is not involved in damage of marine habitat. Some species caught with this trawling method are mackerel, herring, and hoki.
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 a method of fishing that involves actively dragging or pulling a trawl through the water behind one or more trawlers. Trawls are fishing nets that are pulled along the bottom of the sea or in midwater at a specified depth. A trawler may also operate two or more trawl nets simultaneously (double-rig and multi-rig).

A trawl is a large net, conical in shape, designed to be towed along the sea bottom. The trawl is pulled through the water by one or more boats, called trawlers or draggers. The activity of pulling the trawl through the water is called trawling or dragging. Bottom trawling results in a lot of bycatch and can damage the sea floor.
The New England Fishery Management Council voted to work on an amendment to protect Atlantic sea herring, an important forage fish. 'Until the last fish is gone.' Cape Cod fishers worry trawling ...
Fishermen who caught B. vaderi were deep-sea trawling in the South China Sea about 50 nautical miles offshore of the city of Quy Nhon in south-central Vietnam, which is west of the Spratly Islands.
A manta trawl is a net system for sampling the surface of the ocean. It resembles a manta ray , with metal wings and a broad mouth. The net it pulls is made of thin mesh, and the whole trawl is towed behind a scientific research vessel . [ 1 ]
