Selected Resources

Native To: Eurasia (NAS Database)

Date of U.S. Introduction:

  • Bighead carp in 1972;
  • Black carp in early 1970s;
  • Grass carp in 1963;
  • Silver carp in 1973 (NAS Database)

Means of Introduction: Black carp was a "contaminant" in imported grass carp stocks; other three species were imported for aquaculture and for phytoplankton control (NAS Database).


  • Bighead carp: impacts not adequately known, but may "lead to reductions in populations of native species that rely on plankton for food, including all larval fishes, some adult fishes, and native mussels";
  • Black carp: presumed to "negatively impact native aquatic communities by feeding on, and reducing, populations of native mussels and snails, many of which are considered endangered or threatened";
  • Grass carp: direct and indirect impacts via: competition for food; significant changes in the composition of macrophyte, phytoplankton, and invertebrate communities; interference with the reproduction of other fishes; decreases in refugia for other fishes; modification of preferred habitat; predation or competition when plant food is scarce. Has significantly altered the food web and trophic structure of aquatic systems by inducing changes in plant, invertebrate, and fish communities;
  • Silver carp: has the potential to cause enormous damage to native species because it feeds on plankton required by larval fish and native mussels. Is a potential competitor with adults of some native fishes, for instance, gizzard shad, that also rely on plankton for food (NAS Database).
