I have picked up stocked walleye fingerlings a couple of times while chasing panfish. A least the bait size makes sense in that case. I once caught a 5 inch muskie in Hyland Lake in Bloomington. I was fishing for bass with a fairly large spinner and the little maniac smacked it. I talked to the local CO a couple weeks later and he told me they had stocked them recently and were just then getting to posting the muskie signs at the launch ramp and fishing pier. No idea how they have done in that lake, no longer fish it.
