Jigging is probably the most popular way to fish for walleye. A simple jighead with a nightcrawler, leech or minnow will get the job done. There are plenty of anglers that will also use soft plastics, but live bait is preferred for the majority of anglers. Green, chartreuse, orange and glow in the dark colored jigheads seem to be the most productive jigheads, although, other colors will also work.
When fishing vertically, you need to make sure the speed of your boat matches how heavy of a weight you are using with your jighead. The key is to stay vertical so you can feel the bites easier and get a good hookset. Walleye are known for biting light at times. When the bite is light, vertical jigging is by far one of the best ways to catch walleye.
You can also jerk the bait up off the bottom more aggressively and let it fall back down to the bottom. This more aggressive jigging motion tends to work better with minnows, but it will also work with leeches and nightcrawlers. This more aggressive motion helps draw reaction strikes from walleye.
