Whitefish have small mouths. Use same general minnow rig up as Walleye but with smaller hooks. Also you have to pay attention, they don't strike the bait hard and you don't have to set the hook hard, a quick flick should do it. And they are one of the hardest fish to sport fish. You catch one or two as a sport fisherman in your lifetime, you are lucky. Its a rare skill for most people. ... Often they will be in close association with Walleye schools but be deeper down which is why they are sometimes hard to catch on a line because the Walleye are way more aggressive. You should also be on a school of Walleye in deeper water.
