Overview 
Common carp (Cyprinus carpio) are domesticated ancestors of a wild form native to the Caspian Sea region and east Asia. Carp degrade shallow lakes by causing excessive turbidity, which can lead to declines in waterfowl and important native fish species. The common carp was introduced by unintentional release in 1879.

The idea is for biologists to temporarily kill the river so a new electric fish barrier can be briefly shut down for maintenance. Maintenance on carp barrier at standstill Milwaukee Journal Sentinel (11/4) At the same time nearly a half billion dollars is headed toward the Great Lakes as part of President Barack Obama's ambitious ecosystem restoration program, nobody at the moment appears to have the dollars to allow the U.S. Army of Corps of Engineers to do regular maintenance on the new $9 million Asian carp barrier.
