Trawling is a fishing method that involves dragging a large net through the water to catch fish and other marine life. This net, called a trawl, is often pulled behind a boat, allowing fishermen to cover a wide area. Trawling can be done at different depths, targeting various species like shrimp, cod, or herring. While trawling can be an effective way to catch large quantities of fish, it can also harm the ocean environment. The heavy nets can damage the sea floor and unintentionally catch bycatch, which includes non-target species like turtles and dolphins. Sustainable practices are essential to protect marine ecosystems.
