Electric pulse fishing. The pulse trawl: electrodes in the tow direction of the gear cause an electric field above the seabed, which stimulate the flatfish so they come up toward the net. Electric pulse fishing is a fishing technique sometimes used in trawl fisheries which produces a limited electric field above the seabed to catch fish. [1]
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 ...
A fishing trawler is a commercial fishing vessel designed to operate fishing trawls. 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.
Beam trawling is used in the flatfish and shrimp fisheries in the North Sea. They are medium-sized and high powered vessels, towing gear at speeds up to 8 knots. To avoid the boat capsizing if the trawl snags on the sea floor, winch brakes can be installed, along with safety release systems in the boom stays. The engine power of bottom trawlers ...

It is found from the Barents Sea down to the Iberian peninsula and around Iceland and the Faroe Islands. It is often reported in ichthyological check lists for the Mediterranean Sea ...
