We’re excited to share an episode of Teach Me About the Great Lakes featuring the Introduced team! This episode is all about invasive species generally, and invasive crayfish specifically. TMAGL speaks again with Dr. Brian Roth about his work on invasive crayfish and with IISG’s own Greg Hitzroth about the Invasive Crayfish Collaborative. Plus, in a special bonus, we speak with the hosts of Introduced, a highly produced, episodic podcast about invasive species from our colleagues at Wisconsin Sea Grant.

Today’s guests are Dr. Brian Roth of Michigan State University, Greg Hitzroth of Illinois-Indiana Sea Grant, and the producers of the Introduced podcast: Bonnie Willison, Sydney Widell, and special guest Tim Campbell.

On August 25, 2009, the Wisconsin Department of Natural Resources gets a call about small lobsters crawling around a neighborhood pond in Germantown. The extent of the problem is more than anyone bargained for. Here’s the story of the first red swamp crayfish introduced into Wisconsin.

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.
