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.
Gambusia dominicensis, the Dominican Gambusia, is a small freshwater fish species native to Lake Azuei in Haiti and Lake Enriquillo in the Dominican Republic. G. dominicensis is used in the aquarium trade, but no evidence of its presence in trade in the U.S. could be found. It is, however, in trade outside of the U.S. It was introduced around Alice Springs, Australia in the 1940s and 50s for mosquito control. It is not known if this species is still present near Alice Springs, and no negative impacts of this introduction have been documented. G. dominicensis has a medium climate match with the contiguous United States with a high climate match in Florida and a low climate match elsewhere. The certainty of this assessment is low. The overall risk assessment category is uncertain.
