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. Trawls are often called towed gear or ...
In midwater trawling, a cone-shaped net can be towed behind a single boat and spread by trawl doors, or it can be towed behind two boats (pair trawling) which act as the spreading device. Midwater trawling catches pelagic fish such as anchovies , shrimp , tuna and mackerel , whereas bottom trawling targets both bottom living fish ( groundfish ...
Seine fishing (or seine-haul fishing; / s eɪ n / SAYN) is a method of fishing that employs a surrounding net, called a seine, that hangs vertically in the water with its bottom edge held down by weights and its top edge buoyed by floats.

Kyle de Bouter holds up a pair of Patagonia board shorts made of recycled fishing nets, smiling as workers nearby slice old nylon nets to stack into seven-foot square, one-ton bales.
