Introduced Asian carp in North America pose a major threat to the ecology, environment, economy, and way of life in the Upper Midwest and Great Lakes region of the United States and Canada. Asian carp are a group of fish species, which include several known to be invasive , and represent the most urgent potential danger to the ecology of the Great Lakes. The group of fish species known in the United States as Asian carp include several which are invasive. These species of carp cause harm when they are introduced to new environments. Specifically, the four most well-known species of invasive Asian carp are bighead , silver , black , and grass carp. Grass carp can alter the food webs of a new environment by altering the communities of plants, invertebrates, and fish.

AP — Michigan, Illinois and a federal agency have agreed on funding the next phase of an initiative to keep Asian carp out of the Great Lakes by strengthening defenses on a Chicago-area waterway, officials said Thursday. The two states and the U. The structure on the Des Plaines River is a choke point between the Illinois River, which is infested with the invasive carp, and Lake Michigan. The federal share of the design and engineering funds still needs to be provided through annual Corps work plans, said Col. Steven M.
Asian Carp 'eDNA' found in Chicago creek near Lake Michigan. But what does it mean?
On a bleak and biting December morning, a team of state-contracted commercial fishermen at Starved Rock Marina slipped into their waders, salted down their johnboats to protect against ice and launched onto the Illinois River. Armed with thousands of yards of netting, the fleet set course for a cove at Sheehan Island where they suspected a horde of silver and bighead carp, the most abundant and worrisome species of invasive Asian carp, were holed up for the winter. Within less than a half hour, the fishermen transformed the inlet, which is big enough to hold Millennium Park, into an enormous booby trap, layering netting from the shores to the mouth of the bay.
Or, something else is going on. That's alarmingly close. Genetic material can also be transferred on the many hulls of ships and boats passing through the Chicago Area Waterways System as well. Fish and Wildlife Service.
