"ROMEOVILLE, Ill. -- These fish jump. Oh, how they jump. It's common for an Asian carp to leap four feet out of the water and flop into whatever may rumble into its path, be it watercraft or fisherman. They also make a big splash. A 60-pounder is not unusual.

"Every day we go out on the water, the number of fish we see jumping around the boat is just astounding. It's incomprehensible," said Mark Pegg, a fisheries biologist for the Illinois Natural History Survey. "You just have to see it to realize there are that many fish jumping around you.""

Exotic species can cause BIG problems in new habitats. A big headache if one were to jump and smack you on the head. Any ideas for damage control?
