To plunk bait, you will need lead weights from one-half ounce to 2 ounces, depending on the current. Bank sinkers are most commonly used. Number 2 hooks are recommended. To rig sliding sinkers, you will need swivels to act as a stop. Plastic beads can be used between the weight and swivel to protect the knot.
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. This is the most popular method. Use just enough weight to hold the bait in position against the current. Free spool or back reel to allow the bait to move with the current.
