Alex "Turtle" Seidemann casts a net in the Illinois River where he and his team would catch hundreds of silver, bighead, black, grass and common carp.<br />
<br />
In 2010, the Illinois Department of Natural Resources began "harvesting” on a large scale using commercial fishermen. The program removes upwards of 1 million pounds from the Illinois River each year. Yet still, in some places, 75 percent of the river’s biomass — meaning the aggregate of all living material — is Asian carp.

  • Barge cleaner Matt Truhlar works on a barge on the Chicago Sanitary and Ship Canal at Illinois Marine Towing in Lemont. Just a few miles south of the company's dock is an electric fish barrier, which keeps Asian carp from moving up the river toward Lake Michigan. A towboat pushing a barge carrying cargo with a low flashpoint must wait for an assist boat to pull from the other side.<br />
