		Bighead carp can weigh 18 - 23 kg (40 - 50 lbs) by their fourth year (Henderson 1978) and have been documented as large as 40 kg (90 lbs) in their native range (Pflieger 1997).
		Bighead carp migrate upstream to spawning grounds (Jennings 1988) which are characterized by rapid currents with a mixing of water, such as at a confluence of rivers or behind sandbars, stonebeds, or islands (Huet 1970).

	ASIAN CARP
		Bighead carp Hypophthalmichthys nobilis, native to the large rivers of eastern China, were first brought to the U.S. in 1972 by a private fish farmer in Arkansas tom improve water quality and increase fish production in culture ponds.
		Because of its feeding habits, bighead carp is a direct competitor with paddlefish, bigmouth buffalo, and gizzard shad; as well as with all larval and juvenile fishes and native mussels.
		Silver carp have spread throughout the large rivers in the Mississippi basin and are reproducing in off-channel and backwater habitats.

		The bighead carp, an Asian import used to control aquatic vegetation, is known to be present in modest numbers in the Arkansas River and White River.
		Bighead carp are found only in major rivers like the Arkansas and the lower White, and fishermen rarely catch them because they don't take large baits.
		The bighead carp's keel or belly plate is short and near the rear instead of extending all the way underneath the fish as with a silver carp.
