Ecological Risk Screening Summary - Ponticola bathybius (a goby, 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.

Ponticola bathybius is a goby that is native to the Caspian Sea. It was reported as introduced into the Aral Sea, but it did not become established and there is no information on impacts of introduction. History of invasiveness is uncertain. Georeferenced occurrences were not available, so source locations for the climate match were estimated based on verbal descriptions of the species range. Climate match with the contiguous United States was high. High matches were found in the Interior West, while much of the Eastern United States had a low match. Due to lack of information, certainty of assessment is low. The overall risk posed by P. bathybius is uncertain.
