(WEAU) - Lake Arbutus is beautiful place to enjoy the great outdoors, but an unfortunate place to find common carp.
"They have a real sharp spine on their back and all their fins so the bigger ones we have to shock,” said Tim Burns Vice President of Hatfield Sportsman Club.
Fisheries Biologist Dan Hatleli of the DNR says they use a mini boom shocker that sends about 480 volts of electricity into the water.
"The electricity that goes into the water causes an involuntary swimming action in the fish and it attracts them towards the boat, said Fisheries Biologist Dan Hatleli of the DNR.
Tim Burns with the Hatfield Sportsman Club says the bottom feeders are a problem.
"Good vegetation can't get started when the carp come along and chew up all the roots," said Burns.
After the carp is shocked the DNR scoops the fish out of the water with a net and checks that the right species is caught.
"The mortality to the other fish is extremely minimal, if we were out here collecting walleyes or pan fish or something like that, we would have to be a lot more careful," said Hatleli.
The DNR says in past years they’ve brought in as much as two tons of carp that gets hauled away to Chippewa Bi Products.
"They take them to a rendering plant, and throw them in with livestock, and rendered down," said Burns.
This helps not only get rid of carp, but train new DNR employees, because the DNR says most electro-fishing is done at night.
"We’ll let them operate it during the day, so they can see the obstacles and get a feel for how the boat handles and that will better prepare them for when they do this type of exercise at night."
