Overview
The Common Carp 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.

What's New
UM studies potential Asian carp impact in Lake Erie
(1/25)
If they successfully invade Lake Erie, Asian carp could eventually account for about a third of the total weight of fish in the lake, and could cause declines in most fish species — including prized sport and commercial fish such as walleye, according to a new computer modeling study.

Asian Carp Innovative Solutions Competition
(12/23)
The Asian Carp Canada Innovative Solutions Competition is a platform for university and college students to network and showcase their original ideas and solutions which could be used in the prevention, control and/or elimination of Asian carps in the Great Lakes basin.

Research using CO2 keeps even small fry invasive carp at bay
(11/19)
A researcher at the University of Illinois has shown that bubbling high concentrations of carbon dioxide (CO2) into water is a deterrent to invasive Asian carp adults. Recently, the research demonstrated that juvenile fish also experience negative consequences following CO2 exposure.

Asian carp recommendations could take 4 more years
Detroit Free Press (11/4)
Nearly two years after the release of a landmark report on alternatives for keeping Asian carp out of the Great Lakes, federal officials told members of Congress on Wednesday it could be another four years before recommendations for stopping the invasive species at a key chokepoint outside Chicago, Ill., are ready.

Mich. Lawmakers find new urgency to stop Asian carp
The Detroit News (10/23)
Michigan lawmakers in Congress say the results of a new federal study illustrate the urgency to empower the U.S. Army Corps of Engineers to do more to prevent Asian carp from infiltrating the Great Lakes.

Concerns raised about ability to stop Asian carp
Detroit Free Press (10/15)
The U.S. Fish and Wildlife Service again confirmed that small fish may be pulled along by barges going past electrical barriers, reigniting concerns that young Asian carp could be transported into the Great Lakes.
