=== As a pest species ===
Carp in particular can stir up [[sediment]], reducing the clarity of the water and making plant growth difficult.<ref>{{Cite web |last=Gulf States Marine Fisheries Commission |author-link=Gulf States Marine Fisheries Commission |date=3 August 2005 |title=Cyprinus carpio (Linnaeus, 1758) |url=http://nis.gsmfc.org/nis_factsheet2.php?toc_id=183 |archive-url=https://web.archive.org/web/20070818063036/http://nis.gsmfc.org/nis_factsheet2.php?toc_id=183 |archive-date=18 August 2007 |access-date=3 May 2007}}</ref><ref>{{Cite web |last=Florida Fish and Wildlife Conservation Commission |date=2006 |title=Exotic Freshwater Fishes |url=http://floridafisheries.com/Fishes/non-native.html |archive-url=https://web.archive.org/web/20070208232238/http://floridafisheries.com/Fishes/non-native.html |archive-date=8 February 2007 |access-date=5 March 2007}}</ref>

In America and Australia, such as the [[Asian carp]] in the [[Mississippi Basin]], they have become [[invasive species]] that compete with native fishes or disrupt the environment.

''Cyprinus carpio'' is a major pest species in [[Australia]] impacting freshwater environments, amenity, and the agricultural economy, devastating [[biodiversity]] by decimating native fish populations where they first became established as a major pest in the wild in the 1960s. In the major river system of eastern Australia, the [[Murray–Darling basin|Murray-Darling Basin]], they constitute 80–90 per cent of fish biomass.<ref>{{Cite journal |last1=Peterson |first1=Douglas |last2=Pearson |first2=James |last3=Simpson |first3=William |date=2022-05-30 |title=Effects of common carp on water quality and submerged vegetation: results from a short-term mesocosm experiment in an artificial wetland |journal=Marine and Freshwater Research |volume=73 |issue=7 |pages=973–994 |doi=10.1071/mf22008 |s2cid=249222934 |issn=1323-1650|doi-access=free }}</ref>

In 2016 the federal government announced A$15.2 million to fund the National Carp Control Plan to investigate using [[Cyprinid herpesvirus 3]] (carp virus) as a biological control agent while minimising impacts on industry and environment should a carp virus release go ahead.
