When I read this story in this morning's Journal:

The notorious jumping silver carp has made its way into Wisconsin.

The super-sized cousin to the common carp was discovered late last week in Wisconsin waters of the Mississippi River. It is the first time silver carp, one of four species of Asian carp, have been confirmed in the state, according to the state Department of Natural Resources.

The imported fish have been steadily making their way north in the Mississippi River basin since they escaped containment in Arkansas more than three decades ago. Biologists figured it was only a matter of time until the filter-feeding fish that can grow to 60 pounds made it this far north.

Silver carp are trouble for recreational boaters because of their penchant for leaping out of the water. Also, they feast on the bottom of the food chain, and that can have a big impact on native fish that directly or indirectly rely on the same food.

I couldn't help but reminded of this classic from Sesame Street:
