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.
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 groups have raised concerns that this fishing practice may be responsible for significant volumes of by-catch, particularly cetaceans (dolphins, porpoises ...
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. A trawler may also operate ...
Trawling occurs mainly over sandy sediments, but areas of muddy substrate and coarser, gravely substrates are also trawled. [4] A five-year benthic trawl experiment was implemented between 2014 and 2019 with the purpose of determining the environmental impact of demersal trawling in South African waters.
A stern trawler tows a fishing trawl net and hauls the catch up a stern ramp. These can be either demersal (weighted bottom trawling); pelagic (mid-water trawling); or pair trawling , where two vessels about 500 metres apart together pull one huge net with a mouth circumference of 900 meters.

Midwater trawling catches pelagic fish such as anchovies and mackerel, whereas bottom trawling targets both bottom-living fish and semi-pelagic species such as cod, squid, shrimp, and rockfish. Trawling is done by a trawler , which can be a small open boat with only 30 hp (22 kW) or a large factory trawler with 10,000 hp (7,500 kW).
