Trolling for trout has as many variations as there are lures to pull behind a boat. Pictured below is a set up used for Kokanee trout. Notice the rubber band to help cushion the pull from these hard fighting soft mouthed Kokanee.

Corn, eggs, spoons, spinners, and flatfish can all replace the worm. Remember to check the lure action next to the boat before letting line out.
