Although trawling today is heavily regulated in some nations, it remains the target of many protests by environmentalists. Environmental concerns related to trawling refer to two areas: the lack of selectivity and the physical damage which the trawl does to the seabed. [8]
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).
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 ...

The next most important fishery by value is American lobster and Atlantic sea scallop. The Port of New Bedford, Massachusetts is America's #1 Fishing Port with fish landings valued at $369 million. Each year, there are nearly 50 million pounds of sea scallops landed there. [12] The striped bass was driven to low levels early in the 1980s. Catch ...
1: trawl warp, 2: otter boards, 3: longline chains, 4 hunter, 5: weights 6: headline with floats, 7: pre-net, 8: tunnel and belly, 9: codend. Midwater trawling is trawling, or net fishing, at a depth that is higher in the water column than the bottom of the ocean. It is contrasted with bottom trawling.
Stern trawlers are designed to operate in most weather conditions. They can work alone when midwater or bottom trawling, or two can work together as pair trawlers. [30] Freezer trawlers – The majority of trawlers operating on high sea waters are freezer trawlers. They have facilities for preserving fish by freezing, allowing them to stay at ...
Bottom trawling often tears up the ocean bottom and can be very destructive to all bottom dwelling fish. Trawling involves the use of a system of nets deployed on or near the sea floor. Benthic trawling is towing or dragging a net at the very bottom of the ocean. Demersal trawling is towing a net just above the benthic zone.
