Silver carp (a variety of Asian carp) are easily disturbed and will jump as much as 10 feet into the air in response to rocks thrown in the water, passing trains, geese taking off from the water, or just when they unexpectedly find themselves in a tight place. They also jump at the sound of outboard motors, often landing in boats and sometimes striking the passengers. With a boat speed of over 20 mph and fish that can weigh over 20 pounds, this can be disastrous. Jumping fish have seriously injured many boaters and damaged boats. Water skiing on the Missouri River is now exceedingly dangerous because most of the fish jump behind the boat.

Can I eat Asian carp?
Asian carp of all types have white, firm, mild flesh, which is excellent table fare, but all Asian carp also have intramuscular bones in the filets that many people find undesirable. Asian carp feed low on the food web, are fast growing, are low in fat in the filets, and are not usually bottom feeders — all properties of fish that are lower in contaminants. Like any fish taken from inland waters...
Is it possible to eradicate Asian carp once they are in an area?
Eradicating an established population of Asian carp would be extremely difficult and expensive, if possible at all. Potential control methods include the use of fish poisons, physical barriers, physical removal, habitat alteration, or the addition of predators, parasites, or pathogens. Research on Asian carp control is ongoing and documents on the subject are provided through the Invasive Carp...
What is an invasive species and why are they a problem?
An invasive species is an introduced, nonnative organism (disease, parasite, plant, or animal) that begins to spread or expand its range from the site of its original introduction and that has the potential to cause harm to the environment, the economy, or to human health. A few well-known examples include the unintentional introduction of the West Nile virus, chestnut blight, the South American...
What are Asian Carp?
Carp are not native to North American waters, but various carp species have been introduced here since the mid-1800s, much to the detriment of native fish. Although carp eradication measures have been active for over 100 years, long-established species, like the common carp, are present in almost every state. Asian carp (bighead, black, grass, and silver carp) were imported to the United States in...

Science and innovation for battling invasive carp
The U.S. Geological Survey (USGS) is the Federal Government’s independent research agency that conducts research to inform management of invasive species. Bighead, black, grass, and silver carp, which are native to China, were originally stocked in aquaculture facilities to control algae, snails, and vegetation. These species have invaded the Mississippi River and are now established throughout th"Modified Unified Method" of carp capture
Populations of Hypophthalmichthys molitrix (silver carp) and Hypophthalmichthys nobilis (bighead carp), (together referred to herein as “bigheaded carp”) have increased exponentially in the greater Mississippi River Basin. Detrimental effects on native fish and economically important fisheries have occurred where these invasive, filter-feeding fish are abundant. The Unified Method, a harvest technWater-quality sampling plan for evaluating the distribution of bigheaded carps in the Illinois Waterway
The two nonnative invasive bigheaded carp species (bighead carp Hypophthalmichthys nobilis and silver carp H. molitrix) that were accidentally released in the 1970s have spread widely into the rivers and waterways of the Mississippi River Basin. First detected in the lower reaches of the Illinois Waterway (IWW, the combined Illinois River-Des Plaines River-Chicago Area Waterway System) in the 1990USGS science and technology help managers battle invading Asian carp
The U.S. Geological Survey (USGS) conducts Asian carp research focused on early detection, risk assessment, and development of control tools and strategies. The goals are to prevent the establishment of invasive Asian carp in the Great Lakes and to reduce their impacts in the Ohio River and Mississippi River Basins and elsewhere. Managers can use the information, tools, and strategies for early deIdentify potential lock treatment options to prevent movement of aquatic invasive species through the Chicago Area Waterways System (CAWS)
Introduction The Illinois River is a primary tributary of the Mississippi River, connecting with the Mississippi at Grafton, Illinois. The headwaters of the river are at the confluence of the Des Plaines and Kankakee Rivers in eastern Grundy County, Illinois. Approximately 273 miles long, it runs through the heart of Illinois and is the connection between the Mississippi River and Lake Michigan inAsian carp behavior in response to static water gun firing
The potential for invasion of Asian carp into the Great Lakes has ecological and socio-economic implications. If they become established, Asian carp are predicted to alter lake ecosystems and impact commercial and recreational fisheries. The Chicago Sanitary and Shipping Canal is an important biological conduit between the Mississippi River Basin, where invasive Asian carp are abundant, and the GrHydraulic and water-quality data collection for the investigation of Great Lakes tributaries for Asian carp spawning and egg-transport suitability
If the invasive Asian carps (bighead carp Hypophthalmichthys nobilis and silver carp Hypophthalmichthys molitrix) migrate to the Great Lakes, in spite of the efforts to stop their advancement, these species will require the fast-flowing water of the Great Lakes tributaries for spawning and recruitment in order to establish a growing population.

The U.S. Geological Survey (USGS) scientists at the Columbia Environmental Research Center (CERC), Columbia, Missouri, carry out basic and applied research on the ecology of invasive fishes in the Missouri and Mississippi river basins.
