Invasive Fish Species

Black Carp

  • Scientific Name

    Mylopharyngodon piceus - Visit ITIS for full scientific classification. 

  • Description

    • Large, freshwater fish. Elongated body shape, similar in appearance to Grass Carp.
    • Adults are black, dark blue, or brown on their back and sides, and light gray to white on their bellies.
    • Large, smooth teeth in throat adapted to crush the shells of snails, mussels, and clams.
    • Possible for individuals to grow over 5 feet long and up to 150 pounds. 
  • Habitat
    • Bottom dwellers, preferring floodplains and the backwaters of rivers. Also found in reservoirs, irrigation canals, and lakes.
    • Black Carp can tolerate extreme environmental conditions including: low oxygen levels, brackish water, and temperatures ranging from 32-100 degrees F.
  • Invasion Pathways and Distribution
    • In 1973, Black Carp were accidently introduced into a fish farm in Arkansas with a shipment of Grass Carp.
    • They now occur in the Mississippi River and continue to spread to other surrounding states.
    • Asian Carp can spread through fish farming activities, legal and illegal stocking, accidental inclusion in shipments, escape or release to open waters, and natural dispersal.
    • Native to China and Russia.
    • See USGS for a map of current U.S. distribution. 
  • Life History
    • Mating season begins in the summer when the water is warmer than 65 degrees F.
    • Enormous reproductive capabilities. Females migrate to areas of moderate water flow in order to release hundreds of thousands of eggs into the water column. 
  • Impacts
    • Compete with native fishes for resources.
    • Can reduce native populations of the snails, mussels, and clams they feed on.
    • Black Carp also carry parasites and diseases that can then spread to native fishes.
