Species that are considered uncertain risk need a more in-depth assessment beyond the Ecological Risk Screening Summary to better define the species’ risk to U.S. environments.
Erimyzon sucetta, Lake Chubsucker, is a fish native to North America from the Great Lakes to Gulf Coast and along the southern Atlantic Coast. Nonnative populations have been established in some parts of the United States, possibly due to intentional stocking. The History of Invasiveness for E. sucetta is classified as Data Deficient due to the lack of information available on any impacts of nonnative establishment of this species. The climate matching analysis for the
contiguous United States indicates establishment concern for this species outside its native range. Areas of high climate match occurred within this species’ native range, but there were some areas of high match in the northeast and eastern Great Plains that were outside of the native range. The Certainty of Assessment for this ERSS is classified as Low due to the lack of information on the impacts of nonnative establishment for this species. The Overall Risk Assessment Category for Erimyzon sucetta in the contiguous United States is Uncertain.
