Ecological Risk Screening Summary - Cyprinus longzhouensis (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 longzhouensis is a species of carp native to the Pearl River drainage in China and possibly Vietnam. It is reported that the species is used as a food source, however the species has declined since the 1980’s and there are no recent records. The history of invasiveness is uncertain. No records of introductions were found, and no records of this species in trade were found. The climate match for the contiguous United States is medium. Some states in the East had high individual climate scores. The climate match is based on a general description of the species’ range since georeferenced locations were not available. The certainty of assessment is low. The overall risk assessment category is uncertain.
