Ecological Risk Screening Summary - Golden Topminnow (Fundulus chrysotus) - Uncertain Risk

Fundulus chrysotus, the Golden Topminnow, is a small freshwater fish that is native to the Atlantic and Gulf Coastal Plain in the southeastern United States, although it is mostly restricted to the lower Coastal Plain. There have been limited introductions in Arkansas and Texas, and it is thought to be established in Texas. No information on impacts of introductions was found. F. chrysotus is available via the pet trade but no estimates were found regarding quantity or duration of trade. Hawaii lists F. chrysotus as a conditionally approved species; no other State regulations were found during this assessment. The History of Invasiveness for F. chrysotus is classified as Data Deficient due to the lack of information on impacts of non-native populations. The climate matching analysis for the contiguous United States indicates establishment concern for this species outside its native range. The highest matches were found in the Southeast centered around where this species is native. The Certainty of Assessment for this ERSS is classified as Low due to the lack of impact information. The Overall Risk Assessment Category for F. chrysotus in the contiguous United States is Uncertain.
