Ecological Risk Screening Summary - Rutilus aula (a fish, no common name) - High Risk

Species that are considered high risk have a well-documented history of invasiveness in at least one location globally, and a high or medium climate match to the contiguous United States.

Rutilus aula is a cyprinid native to the Adriatic basin from the Soca to the Po river drainages. Rutilus aula has not been recorded as being used for commercial purposes but is recognized as a game fish. This species has been introduced outside of its native range into central and southern Italy but information on how it got there could not be found. Even though the means of introduction could not be found, it was documented as causing the local extirpation of Rutilus rubilo in its introduced range. Because of this negative impact, the history of invasiveness is High. The overall Climate 6 score for Rutilus aula was also High. Much of the contiguous United States had a low to medium match with areas of high match located around the Great Lakes and New England coast. The overall certainty of assessment is Low due to a lack of information on the species itself and a lack of supporting impact information in English. The overall risk assessment category for Rutilus aula is High.
