Trawl, e.g. is a type of fishing NET that is dragged along the bottom of the ocean or lake to catch fish. It is usually made of a heavy-duty mesh material and is designed to be strong enough to withstand the force of the water and the weight of the fish. The NET is usually attached to a boat and is dragged behind it. Trawling is a common method of fishing and is used to catch a variety of species, including cod, haddock, and shrimp.
