Troll ships are specialized fishing vessels designed for catching fish using a method called trolling. This technique involves dragging baited lines or lures through the water to attract fish. Troll ships are equipped with multiple fishing rods and reels, allowing them to cover large areas of the ocean efficiently. These ships are commonly used to catch species like salmon, tuna, and mackerel. They often feature advanced navigation and sonar systems to locate fish schools. Troll ships play a significant role in commercial fishing, contributing to the global seafood supply while adhering to regulations to ensure sustainable practices.
