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.
Alburnus escherichii, Caucasian Bleak, is a freshwater fish species native to Turkey in the Sakarya river drainage and Kizilirmak river. Alburnus escherichii has been reported as introduced in Lake Beyşehir basin in Central Anatolia, and in the Manavgat river in the Mediterranean basin; only the former location is known to have an established population and there is no information on whether there were impacts from the introduction. The history of invasiveness is classified as Data Deficient. The climate match for the contiguous United States is High. Most of the contiguous United States had a high to medium match with areas of highest match found in the Intermountain West. The certainty of assessment is Low due to a lack of information on impacts of introduction. The overall risk assessment category for Alburnus escherichii is Uncertain.
