Trolling

Category: Techniques

Trolling is a fishing technique where lures or bait are pulled behind a moving boat at controlled speeds to cover large areas of water and locate fish that are spread across open-water structure. Unlike casting techniques where the angler targets specific visible cover, trolling is a search-and-locate strategy that uses the boat's movement to present baits at precise depths and speeds across miles of water. Trolling is the dominant technique for walleye, striped bass, lake trout, salmon, and musky in open-water environments. Speed control is critical — different species and lure types require specific trolling speeds, typically measured in tenths of a mile per hour using GPS. Planer boards spread multiple lines away from the boat's wake, increasing the width of the trolling pattern. Downriggers enable precise depth control by attaching the line to a weighted cable that runs at a set depth. Lead core line sinks at a predictable rate per length of line deployed, providing depth control without additional hardware. Modern trolling integrates sonar, GPS waypoint navigation, and water temperature mapping to identify fish-holding structure, set precise trolling paths, and maintain the exact depth and speed that current conditions require.
