Ecological Risk Screening Summary - Cyprinus megalophthalmus (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 megalophthalmus is a species of carp native to Lake Erhai in southern China. Catches in scientific surveys of the lake reportedly declined through the 1970’s. The history of invasiveness is uncertain. No records of introduction were found. No records of this species in trade were found. The climate match for the contiguous United States is low. There were small areas of medium match in Florida, Texas, and Arizona. The certainty of assessment is low. There is minimal information available for the species. The overall risk assessment category is uncertain.
