A trolling lure is a type of artificial bait designed specifically for trolling—a fishing method where the lure is dragged through the water behind a boat. It mimics the swimming movements of prey such as small fish and squid to attract large predatory fish (e.g., tuna, mackerel, bass). Available in various forms including fish-shaped, squid-shaped, and feathered hooks, some trolling lures feature reflective panels or sound-producing devices to enhance their fish-attracting effect. They are adapted to different water layers (surface, mid-water, deep) and current speeds, widely used in saltwater fishing and for targeting large freshwater species, serving as a key tool for catching big fish in offshore or open waters
