I was honored recently to guest host “Chicago Newsroom,” the weekly public affairs show hosted by media legend Ken Davis and broadcast over the CAN TV network. My guests were the estimable Chris Robling, vice president at Jayne Thompson Associates and a frequent Republican commentator, and Dave Lundy, principal at  Aileron Communications and a frequent Democratic commentator. We discussed Chicago Mayor Rahm Emanuel’s tenure so far as well as state politics and the upcoming governor’s race. You can watch the show by clicking on the photo above.

By coincidence, the same day, I was also a guest on “Morning Shift” over WBEZ Chicago Public Radio discussing the arrest of two community leaders on charges of lobbying for Zimbabwe President Robert Mugabe. You can listen to the show here:

By pulling out a single strand of hair, your DNA instantly becomes environmental DNA or eDNA and this concept may help us save the Great Lakes from the potential devastation of the Asian carp. I didn’t understand this until I met Chris Jerde at the University of Notre Dame on a trip with my journalism classmates.

Jerde’s current job is to extract eDNA from water samples to search for a trace of Asian carp but this process can be used for other things to in the near future. He demonstrated by filtering water through special filters that captured algae and other microorganisms, allowing the eDNA to collect in sterile containers for testing.

“The process we use now will help us find the location of the carp, and in the future this process will help us figure out multiple species of fish,” Jerde said. “How many there are, and where they’re located, which is way better than counting them.”

Asian carp was seen as a quick and easy solution to help clean up some fish farm ponds near the Mississippi River. But as they have made their way toward the Great Lakes, they created a whole different issue. The Asian carp has a giant appetite: It eats everything, which means that it changed the food chain and natural rhythm of the rivers and lakes.

Asian carp has been around for awhile. With large mouths and the ability to filter feed, the carp were originally brought from China to clean up the lakes that serve as fish farms in Arkansas. The Arkansas floods in the 1970s caused the fish farms to break open and the Asian carp got into the Mississippi River. The Clean Water Act was passed in 1970 and people were focused on improving the water quality. So people knew Asian carp could be a problem. Asian Carp are found all over the world and there are many in Canada’s water sheds.

“The blue whale of freshwater” – that’s how Chris Jerde, research assistant professor at the University of Notre Dame, describes Asian carp. Among the 185 invasive species in the Great Lakes, Asian carp has been the biggest problem. The various species of Asian carp open their mouths and eat “anything” in their path, as Jerde said, growing up to 100 pounds and leaving everything else behind to starve or just barely survive.

But no one can seem to find Asian carp.

That’s where Jerde’s eDNA test comes in. As Jerde showed us atthe Notre Dame Linked Experimental Ecosystem Facility on a bright, hot, empty yet peaceful spot at St. Patrick’s Park, the eDNA test begins by filtering water through something that looks like a coffee filter. It sorts out the rocks and other things in the water, giving him a pure sample of organic particles. The eDNA test looks for DNA from fish and other organisms that he can trace. You can trace the DNA if an Asian carp has been in the water, even if you can’t physically find the fish.
