Ecological Risk Screening Summary - Cyprinus hyperdorsalis (a carp, no common name) - Uncertain Risk

Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments. This additional information will help inform decisions on where, when, and how the species may be used to minimize risks of them becoming invasive.

Cyprinus hyperdorsalis is a species of carp native to the Black River basin in northern Vietnam. It is reported as being consumed by the local population but also that the species has not been seen since the construction of dams on the river. The history of invasiveness is uncertain. No records of introduction were found and this species is not found in trade. The contiguous United States had a low climate match except for southwest Florida which had a medium match. The certainty of assessment is low. The overall risk assessment category is uncertain.
