I've never heard of this type of fish and I had to google my way to find more information. It's one of the Great Lakes invaders that endanger the fishing industry. Via Boinboing.net I found this clip of a repellant that induces a panic reaction. This is a clip of the University of Michigan.
Fascinating stuff.
