Thanks to our guests Tim Campbell, Pete Jopke, Tim Zabel, Heidi Bunk, Scott Van Egeren, Esquire Estates residents Doug and Mary, Dr. Jake Vander Zanden, Erin Vennie-Vollrath, Chris Hamerla, Dr. Stephanie Peay.

Wisconsin Sea Grant takes a trip to the world’s largest electric fish dispersal barriers, just south of Chicago. These barriers are sending electricity into the canal for one purpose- to keep Asian Carp from swimming into the Great Lakes. 

EDIT: In this episode, we state that the dense and reproducing carp population is 20 miles downstream of the electric carp barriers. This is incorrect - the dense and reproducing Asian Carp population is located 100 miles downstream of the barriers in the Peoria and La Grange pools of the Illinois River.

Special thanks to our guests Duane Chapman, Tim Campbell, Kevin Irons, Elena Blevins and Titus Seilheimer. Thank you to the US Army Corps of Engineers and Chuck Shea for a tour of the electric barriers.
