Ecological Risk Screening Summary - Marmara Barbel (Barbus oligolepis) - 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.

Barbus oligolepis is a cyprinid fish native to northwestern Turkey. The species has a medium climate match to the contiguous U.S., and based on climate match information, it is plausible that B. oligolepis could establish populations if introduced into areas of the western U.S. There are no reports of introductions of B. oligolepis outside of its native range at present. Freyhof (2014) noted that B. oligolepis has been able to cope with threats in its native range and remain abundant, suggesting adaptability. Without known introductions from which to draw expectations of potential impacts to the U.S., the overall risk assessment for B. oligolepis is uncertain.
