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.
Top-mouth Carp (Cyprinus ilishaestomus) is a species of carp native to Lake Qilu in southern China. It has been used commercially in the past by local communities. A specimen hasn’t been caught in a scientific survey since the 1970s. The history of invasiveness is uncertain. No records of introduction were found, and this species is not found in trade. The climate match was low. There were small areas of medium match in southern Florida, Texas, and Arizona. The certainty of assessment was low. The overall risk assessment category is uncertain.
