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.
Bayou Killifish (Fundulus pulvereus) is a fish that can be found in waters with a wide range of salinity. It is native to the Gulf of Mexico, from Alabama to Corpus Christi, Texas, and the Atlantic Coast from the Chesapeake Bay to northern Florida. F. pulvereus has a high climate match with the contiguous United States, with highest matches in its current range along the Southeast coast from Texas to North Carolina excluding southern Florida. However, RAMP (Sanders et al. 2018) was not developed for use in assessing climate match for marine species so the climate match in a marine environment cannot be assessed with an ERSS. There have been no documented introductions of F. pulvereus so no information is available on the impacts of introduction and the history of invasiveness is uncertain. The overall risk categorization for F. pulvereus is uncertain, and certainty of this assessment is low.
