Trawlers are fishing vessels designed to catch fish by dragging a large net through the water. This method, known as trawling, allows fishermen to capture a wide variety of fish species, including cod, shrimp, and herring. Trawlers can operate in both deep and shallow waters, depending on the type of fish being targeted. These boats come in various sizes, from small, local vessels to large commercial ships. Trawlers are equipped with powerful engines and specialized gear to handle the heavy nets and the catch. They play a significant role in the global fishing industry, providing seafood for markets and restaurants worldwide.
