【 摘 要 】

Four species of non-indigenous Asian carp are expanding their range in U.S. waterways, resultingin a variety of concerns and problems. Three species—bighead, silver, and black carp—are ofparticular note, based on the perceived degree of environmental concern. This report examines current controversy relating to what measures might be necessary and sufficient to prevent movement of Asian carp from the Mississippi River drainage into the Great Lakes through the Chicago Area WaterwaySystem. Movement of Asian carp into the Great Lakes is ultimately of concern because increasednumbers of carp in the Great Lakes increases the risk that Asian carp will establish reproducingpopulations in these waters. Bills have been introduced in the 111th Congress to direct actions toavoid the possibility of carp becoming established in the Great Lakes.
