Biologists Implant Trackers in Asian Carp

June 18, 2007 -- Greg Conover scraped away some of the fish’s belly scales and made a smooth 2-inch incision, declaring that this particular 3-foot, 20-pound bighead carp was one of the lucky ones. It and other species of invasive Asian carp that have overrun the Illinois and Mississippi rivers, after all, don’t often make it back to the water once they’ve been in contact with man.

Considered a scourge by fish biologists like Conover and anglers alike, many carp have flopped their last on the decks of boats, only to be unceremoniously tossed back overboard.

But not this monster — now known as No. 1047 to Conover and his cohorts — which over the next two years will help scientists learn more about the behavior of Asian carp and, perhaps, prevent the species from invading the Great Lakes. Read the following two articles to get the details.

"Conover and fellow fish biologist Nate Caswell, who both are stationed in Marion, tagged 30 bighead and silver carp one week this spring from two Illinois River pools near what is thought to be the species’ current northernmost reach: the Starved Rock and Marseilles pools in LaSalle County."

"Like record numbers of silver and bighead carp, Asian species that have invaded the Illinois River from the South. The fish and wildlife crew working the river near Starved Rock State Park said this week’s sample catch was at least double that of a year ago."
