Trawling is a fishing method that involves dragging a large net through the water to catch fish and other marine creatures. This net, called a trawl, is often pulled behind a boat, allowing fishermen to cover a wide area. Trawling can be done at various depths, targeting different species like shrimp, cod, or herring. While trawling is effective for catching large quantities of fish, it can also harm the ocean floor and unintentionally catch non-target species, known as bycatch. To address these concerns, some fishermen use more sustainable practices, such as selective fishing gear, to minimize environmental impact.
