Asian carpany of several species of fish belonging to the carp family Cyprinidae that are native to eastern Asia, particularly China and Russia, and naturalized in some American waterways. The grass carp Ctenopharyngodon idellabighead carp Hypophthalmichthys nobilisblack carp Mylopharyngodon piceusand silver carp Hypophthalmichthys molitrixfollowing their accidental introduction into waterways in the United Statesare collectively referred to as Asian carp. Floods and bait release by sport fishers allowed members of these species, which had proved invasive in other parts of the world, to colonize the Mississippi River system.
The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected.
Common Carp, Cyprinus carpiowhile originally from Asia, arrived in North America much earlier and is not one of those species referred to as Asian carps. Click here for more information. All are members of the cyprinid family, which includes carps and several varieties of minnows.
The silver carp Hypophthalmichthys molitrix is a species of freshwater cyprinid fisha variety of Asian carp native to China and eastern Siberia. By weight more silver carp are produced worldwide in aquaculture than any other species of fish except for the grass carp. Silver carp are usually farmed in polyculture with other Asian carpor sometimes with catla or other fish species. The species has also been introducedor spread by connected waterways, to at least 88 countries around the world.
These carps are all native to the rivers, reservoirs and lakes in China and southern Russia. All 4 species have escaped into the wild in North America and 3 of these species have now established self-sustaining populations, particularly in the Mississippi waterway system, although Black Carp have likely established as well. Vibrations in the water excite Silver Carp causing them to jump up to 3 metres 9 feet out of the water.

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.
Scott Neuman. Asian carp, jolted by an electric current from a research boat, jump from the Illinois River near Havana, Ill. The U.
Rebekah Anderson, a biologist with the Illinois Department of Natural Resources, had just dropped her phone in the water. There was no real chance of recovering it, but she and Ronnie Brown were peering down, wondering if it could be salvaged, when Brown saw a fish laying in their net close to the surface. Her mind raced in response.
Several species of heavy-bodied cyprinid fishes are collectively known in the United States as Asian carp. Cyprinids from the Indian subcontinent—for example, catla Catla catla and mrigal Cirrhinus cirrhosus —are not included in this classification and are known collectively as "Indian carp". All the above, except largescale silver carp, have been cultivated in aquaculture in China for over 1, years.
