Comments: While it is fundamentally benthopelagic, as an active species it swims just below the water surface and is well known for its habit of leaping clear of the water when disturbed. |
Sociability / Life stage (?) |

Reproductive frequency (?) | Iteroparous References (not structured): Chapman D (2004) Facts about Bighead and Silver carp. USGS, Columbia Environmental Research Centre. http://www.cerc.usgs.gov/pubs/center/pdfDocs/Asian_carp-2-2004.pdf |

Developmental trait (?) | Spawning References: Chapman D (2004) Facts about Bighead and Silver carp. USGS, Columbia Environmental Research Centre. http://www.cerc.usgs.gov/pubs/center/pdfDocs/Asian_carp-2-2004.pdf Comments: Silver carp spawn in late spring and summer, when the temperature of the water is relatively high. From April to August, either because of the rainstorms or the swollen upper reaches of streams and rivers, its broodstock are concentrated in spawning locations where conditions are favourable, and the current swift, complicated and irregular. |
Characteristic feeding method / Life stage (?) |
References (not structured): Chapman D (2004) Facts about Bighead and Silver carp. USGS, Columbia Environmental Research Centre. http://www.cerc.usgs.gov/pubs/center/pdfDocs/Asian_carp-2-2004.pdf Comments: Silver carp are typical planktivores, the gillrakers being the main means of filtration. Silver carp consume diatoms, dinoflagellates, chrysophytes, xanthophytes, some green algae and cyanobacteria ('blue green algae'). In addition, detritus, conglomerations of bacteria, rotifers and small crustaceans are other major components of their natural diet. |
Mobility / Life stage (?) |
|
Salinity tolerance range (?) | Exact range: 0 - 13.1 References: Al-Faiz, N. A. 2011. Salinity tolerance of silver carp Hypophthalmichthys molitrix fingerlings transferred suddenly and gradually to a different saline. In The 4th international scientific conference of Salahaddin University-Erbil, 18 (20), pp. 524-527. Abdullah, S. A. G. 2016. Effect of Different Concentration of Salinity on the Survival and Feeding of fingerling, Silver Carp (Hypophthalmichthys molitrix)(Valenciennes, 1844). Mesopotamian Journal of Marine Sciences, 31(1), pp. 53-60. Comments: The salt concentrations less 13.1 g/L were normal, except for abnormal and temporary behaviors. High concentrations of Salinity (14 ppt) led to killed all fish juveniles exposed after 24 hours due to low ability to tolerate high concentrations of salinity. |
Habitat modifying ability potential (?) | Keystone species References: Domaizon I, Devaux J (1999) Experimental Study of the Impacts of Silver Carp on Plankton Communities of Eutrophic Villerest Reservoir (France), Université Blaise Pascal Clermont II. Aquatic Ecology 33(2):193-204 Comments: The species has been introduced in many countries all over the world for two reasons; aquaculture and to control plankton in nutrient-rich ponds and wastewater treatment plants. Their ability to control algal blooms is rather controversial. It was reported that silver carp is efficient in controlling the algal bloom if the right number of fish is used. It is because silver carp can efficiently filter algae >20 µm in size, consequently the number of the smaller algae increases as a result of lack of grazing by the fish and by increase in nutrient by internal loading. |
Toxicity / Life stage (?) | Not relevant |
Bioaccumulation association (?) | Anthropogenic chemical compounds Natural toxins References: Chen, J., Xie, P., Zhang, D., Ke, Z., Yang, H. 2006. In situ studies on the bioaccumulation of microcystins in the phytoplanktivorous silver carp (Hypophthalmichthys molitrix) stocked in Lake Taihu with dense toxic Microcystis blooms. Aquaculture, 261(3), pp. 1026-1038. JafarI, S. M., SobHanarDakanI, S. 2014. Determination of heavy metal (Cu, Pb and Zn) concentrations in muscle tissue of Hypophthalmichthys molitrix, Cyprinus carpio and Ctenopharyngodon idella caught from Zarivar Wetland, Western Iran. Current World Environment, 9(3), 923. Comments: The phytoplanktivorous silver carp is an important biomanipulation fish to control cyanobacterial blooms and is also a food fish with the greatest production in China. |
Known human health impact? | Known References: Jawdhari, A., Mihăilescu, D. F., Fendrihan, S., Jujea, V., Stoilov-Linu, V., Negrea, B. M. 2022. Silver Carp (Hypophthalmichthys molitrix)(Asian Silver Carp) Presence in Danube Delta and Romania—A Review with Data on Natural Reproduction. Life, 12(10), 1582. Comments: Threats to humans are significant, including transfer of zoonotic pathogens and bodily injury and property damage from jumping fish. Fish is well known to be rich in proteins, polyunsaturated fatty acids, lipid-soluble vitamins, and micronutrients. |
Known economic impact? | Known References: Jawdhari, A., Mihăilescu, D. F., Fendrihan, S., Jujea, V., Stoilov-Linu, V., Negrea, B. M. 2022. Silver Carp (Hypophthalmichthys molitrix)(Asian Silver Carp) Presence in Danube Delta and Romania—A Review with Data on Natural Reproduction. Life, 12(10), 1582. Comments: For instance, silver carp ranked second in the world’s aquaculture in 2018 with a global production of 4,822,794 tons. |
Known measurable environmental impact? | Known References: Nico, L., G. Nunez, E. Baker, P. Alsip, Redinger, J. 2024. Hypophthalmichthys molitrix (Valenciennes in Cuvier and Valenciennes, 1844): U.S. Geological Survey, Nonindigenous Aquatic Species Database, Gainesville, FL, and NOAA Great Lakes Aquatic Nonindigenous Species Information System, Ann Arbor, MI, https://nas.er.usgs.gov/queries/greatlakes/FactSheet.aspx?Species_ID=549, Revision Date: 5/31/2024, Peer Review Date: 1/22/2015, Access Date: 7/16/2024 Comments: The introduction of silver carp has also resulted in the decline of several native fish species, including the bighead carp (Hypophthalmichthys nobilis), which is closely related to the silver carp. The decline of these native species can have cascading effects on the local food web and ecosystem. |

Comments: H. molitrix, were first brought to the United States and introduced into aquaculture ponds and wastewater treatment facilities. Soon after their introduction, they escaped containment and began establishing populations. |
