Had that happen to me down by Lansing camping with the Boy Scouts. Northern took my walleye but he spit it out at the boat. A really funny one happened this spring down by Goose island trolling for walleye with a wallydiver I felt a hit and realed it in,felt like a fish, pulled it out of the water and hanging off my wallydiver with the treble hook in it’s mouth was a schad the same size as the wallydiver. I’ve had little bass do that but was a first for trolling.
