Range Extent Comments

Native to Amur basin and flatland rivers of eastern Asia. Introduced in many localities in United States for control of aquatic vegetation. Widespread and increasing in lower and middle Mississippi Valley, spotty elsewhere. Natural reproduction has been recorded in the Mississippi, Missouri, Trinity (Texas), Red, and Washita (Oklahoma) rivers (Hargrave and Gido 2004).

Ecology & Habitat

Habitat

Lakes, reservoirs, ponds, pools, and backwaters of large rivers. Tolerant of diverse conditions of temperature, oxygen level, and salinity. Eggs float until hatching.

Ecology

Strong schooling tendency. May cause increase in turbidity and alkalinity in waters where introduced; may compete with and prey upon native and exotic fishes (Sublette et al. 1990). In Arizona, biomass of largemouth bass increased in direct proportion to biomass of grass carp, perhaps because removal of vegetation by carp increased vulnerability of forage fishes to bass predation (see Sublette et al. 1990).

Reproduction

May spawn in spring and summer. Eggs hatch in 16-60 hours at 17-30 C. Sexually mature in 4-5 years in temperate areas. May live 15-20 years or more.
