In this June 13, , file photo, Asian carp, jolted by an electric current from a research boat, jump from the Illinois River near Havana, Ill. The site is a crucial choke point in an aquatic pathway between the lake and the carp-infested Illinois River. The plan represents a compromise between proposals to erect barriers that would seal off Lake Michigan from the river and less drastic measures such as stepped-up commercial fishing. Environmentalists and states including Michigan had argued for physical separation, while Illinois and Indiana contended that it would disrupt cargo shipping and that a Chicago-area electric barrier was keeping the carp at bay. The Corps says the leading edge of adult bighead and silver carp — the most feared of several Asian species because they gorge on plankton that other fish need — is about 4 miles from the Brandon Road complex. The expected completion date is March

Dear EarthTalk : What exactly are Asian carp, and why are they such a big problem lately? Introduced in the southeast to help control weeds and parasites in aquaculture operations, these fish soon spread up the Mississippi River system where they have been crowding out native fish populations not used to competing with such aggressive invaders. Asian carp are hardy, lay hundreds of thousands of eggs at a time and spread into new habitat quickly and easily. To wit, they can jump over barriers such as low dams. Also, flooding has helped the fish expand into previously unattainable water bodies. Federal and state governments have spent millions in tax dollars accordingly to prevent the carp from making their way into the Great Lakes, but an elaborate underwater electric fence constructed to keep them out has not worked as well as hoped, and policymakers are reviewing other options now. In the states of Michigan, Minnesota, Ohio, Pennsylvania and Wisconsin filed suit in federal court against the U.
Asian Carp Overview
Carp are a freshwater fish species from the family Cyprinidae, a group of fish native to Europe and Asia. Carp are not new to Wisconsin; in fact, certain species have been living in our lakes since the s! Despite their longtime presence, carp are still considered an invasive species with harmful impacts on native ecosystems. Believe it or not, common carp were actually brought intentionally into the U. Native to Europe, they were originally intended to be a game fish and source of food.
Andrew Reeves made a trip in to a public library in Cleveland, Ohio, to take in what he expected to be a quiet meeting hosted by the U. Army Corps of Engineers on what to do about Asian carp. Today, the invasion of grass, bighead and silver carp is seen as a threat to fisheries throughout North America, including the Great Lakes. Reeves, an environmental journalist in Toronto, Ontario, Canada, knows all the more how serious the issue remains. Asian carp have been found in the Mississippi River in Minnesota.
