"There's a number of either purposely introduced, or accidentally introduced, species that have provided quite a recreational resource," said George Madison, fisheries supervisor for the Michigan Department of Natural Resources for the Western Upper Peninsula. "So while smelt can be desired by people, or brown trout or rainbow trout, it's very clear that they out-compete the native species."
