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.

Similar to bottom trawling, midwater trawling involves towing a large net through the water column. Trawls are designed to capture and trap the target species inside the codend as the net is hauled through the water.

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.

Bottom trawling is a fishing practice that herds and captures the target species by towing a net along the ocean floor.

Bottom - or demersal - trawling is a fishing method that uses towed nets to catch fish and other marine species living on or close to the seabed. Bottom trawling includes several different types of fishing gear that use a cone-like net with a closed end (cod-end) that holds the catch.

Trawling is one of the most harmful fishing methods. Enormous nets as wide as a football field are dragged through the water or across the seafloor, capturing almost everything in their path while damaging vulnerable habitat.

2021年6月2日 · A trawl is a method of net fishing where a funnel-shaped net (much like a windsock) is towed behind the boat to capture fish. There are bottom trawls, which primarily target groundfish that live on or near the seafloor, and mid-water trawls (also known as pelagic trawls) that target fish in the mid-and surface water column like Pacific Whiting.

Fishing Vessels using this gear: Trawlers range in size from smaller undecked boats, powered by outboard engines up to large freezer trawlers and factory trawlers which fish in the most distant waters. Fishing Operations: Trawling is the operation of towing a net to catch fish and/or shellfish.

Trawling is the practice of towing a sizable net behind a boat through the sea. The net is typically supported or weighted to keep it open by a trawl door and can be dragged down the water column or along the ocean floor (bottom trawling) (pelagic trawling).
