| What is a Asian carp? |
|
Asian carp include bighead carp (Hypophthalmichthys nobilis, black carp (Mylopharyngodon piceus), grass carp (Ctenopharyngodon idella), and silver carp (Hypophthalmichthys moltirx). They out compete native fish, eat massive amounts of vegations, reduce water clarity and quality, threaten mollusk populations, and aggressively battle native fauna for resources. Boaters have been injured by silver carp because they commonly jump out of the water and into or over boats in response to outboard motors.

| Where? |
|
Asian carp are native to Eurasia and were introduced to the United States in the 1960’s by Arkansas fish farmers to control pest species of vegetation, algae, mollusks, and crustaceans. The black carp was also imported for use as a food fish and to contain the spread of parasitic trematodes found in snails at catfish farms. Asian carp are found in the Mississippi River and Illinois Rivers, Lake Michigan and Lake Erie.

The common carp, also from Eurasia and introduced as a food fish in the United States in the 1800s, has similar features. The common carp has more of a sucker- type mouth (very fleshy lips), and their eyes are located where you would expect them to be on a fish, towards the top of the head. Common carp have two pairs of barbells on the side of the upper jaw and large scales. Asian carp have more of typical fish looking mouth, and their eyes are located lower on the head.
