JANESVILLE, MN - The Minnesota Department of Natural Resorces is taking drastic steps to keep invasive carp from taking over our lakes.
Craig Soupir, area fisheries supervisor for DNR, said: "From a biological perspective, like I said, these fish actually eat zooplankton, which can really impact our natural food webs, and our lakes and rivers.  So it has a negative impact on our native fish and mussels."

They're installing electric barriers on Mayhew Creek in Waseca County and in the Madison Lake outlet to keep the carp out.

"So, it electrifies the water and through that action, fish move up from downstream and they start to interact with that field and they can sense it.  They either avoid it altogether and don't try to pass through or if they do try to pass through, the electricity immobilizes them so they can't use their muscles.", Soupir said.

The fence does not kill the fish.  The stunning effect is only temporary. 

DNR has had good results with the system in other places.

"There's been a couple electric fish barriers installed down in the Windom area to prevent these invasive carp from moving into some of the watershed and into the Minnesota River and other places.  So, yeah, they've been used, they're fairly effective.", he said.

The barriers will use live electric current, so they can be dangerous to people.

"We just encourage people to stay away from these electric fish barriers so nobody gets hurt and they continue to function the way we want them to.", he said.

The project began back in 2013.  Construction on the electric fences should be completed sometime in October.
