A lively minnow will keep your presentation in motion if you aren't jigging feverishly. More often than not, an actively jigged minnow part will outperform a whole minnow hanging from an inactive spoon. The tastiest part of a minnow is the head. Cut or pinch-off the head just behind the gill plates. Thread a single barb crosswise just behind the minnow's eyes.
Spoons require more intense jigging than a simple lead head jig.
Don't be afraid to raise and lower a jigging spoon 2 to 3 feet even when you are fishing in less than 15 feet of water. The fluttering action generated by a descending spoon appeals to walleyes. The rapid thumping churns-up bottom sediment, hence enticing prowling walleyes. Allow the spoon to sit motionless for at least 10 seconds between jigging sequences. To digress, tip-ups are not the primary means for catching winter walleyes, but they do effectively act as a tool of experimentation.
