Bottom trawling consists in towing a fishing net along the sea floor to catch fish or other marine species. Bottom trawling can be contrasted with midwater trawling (also known as [[Industrial and Pelagic Trawl Catch|pelagic trawling]]), where a net is towed higher in the water column. 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). Bottom trawling can be carried out by one trawler or by two trawlers fishing cooperatively (pair trawling). | |||
