Worms are the most common Northern Pikeminnow bait. Chicken liver is the next most popular bait. Make sure it is fresh and keep it cold to prevent it from getting too soft to stay on the hook. Cut-bait (strips cut from fish), fish entrails, skin from fried chicken, salmon eggs, grasshoppers, crayfish tails, and shrimp are also popular.
Chicken liver balls are a great bait to use for pikeminnow when you are sitting on anchor in a hole and looking to draw hungry fish. Northwest Sportsman Magazine demonstrated this Henny Penny's Pikeminnow Bait technique in their June 2016 edition.
