jig and minnow can catch walleye in almost any situation. But try an assortment of crankbaits and swiming paddle tail jigs to cover area and get those more aggresive fish. When I was younger I though jig and live bait was always number one. I now feel differently and catch way more walleye on cranks, and swim jigs. half oz swim baits with strong thump vibrations, and cranks like deep dive husky jerks, Minnow raps, and bomber model A's are usually good too. Any minnow/shad color can be a trustworthy bet. Almost any rapala that runs in the right depth for how deep you are fishing will catch walleye.
When it comes to jig and bait which is also very deadly but a little more tedious, crawlers and leeches are good depending on the season. When it comes to minnows you wanna keep em lively and fat. The more they try to fight their way off the hook the better action it shows to the walleye. But dead minnows are fine too. keep tapping em up and down of the bottom with little wrist twitched kinda like ice fishing and you cant go wrong. usually i have the best luck on a small white or grey tube jig as a plastic trailer, im talkin crappie size. but often no trailer can be best. The lighter a jig you can use, the better, it all depends on how effectively you can fish it in the depth you are fishing.
