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 ...
In accordance to these laws, US fisheries require trawling vessels to use turtle excluder devices (TEDs) that mitigate the capture of turtles in trawl nets. [34] This extends to the use of additional TEDs and the promotion of sustainable fishing practices. [34] The three major laws include: Endangered Species Act (ESA).
Setting a trawl. Trawling is an industrial method of fishing that involves pulling a fishing net through the water behind one or more boats. The net used for trawling is called a trawl. This principle requires netting bags which are towed through water to catch different species of fishes or sometimes targeted species.
Demersal fish – fish that live in the demersal zone. Examples are cod, flounder and snapper. Compared to pelagic fish, demersal fish contain little oil. See also bottom feeder. Demersal trawling – trawling on or near the bottom of a sea or lake. See also bottom trawling. Depletion – reducing the abundance of a fish stock through fishing.
Pair trawling is a fishing activity carried out by two boats, with one towing each warp (the towing cables). As the mouth of the net is kept open by the lateral pull of the individual vessels, otter boards are not required.

It is found in huge schools. In Northwest Pacific catches of Pacific cod by the United States trawl fishery and joint-venture fisheries increased from less than 1,000 tonnes (1,100 short tons) in 1979 to nearly 91,000 tonnes (100,000 short tons) in 1984 and reached 430,196 tonnes (474,210 short tons) in 1995.
Today, trawl fishing is the main industrial method of catching white fish. These trawlers can catch and store massive amounts of fish. They possess highly sensitive electronic equipment and remove the chance element from fishing. They operate by trawling the nets along the sea bed where the kind of fish they want to catch are located.
