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.
Malapterurus tanoensis is catfish native to Ghana in western Africa. There is little information available for this species. Some species in this genus can produce electric discharges to stun prey and for defense, but it is unknown if this is one. The history of invasiveness is uncertain. It has not been reported as introduced or established outside of its native range. There is no information on the trade of M. tanoensis. The climate match analysis resulted in a low match for the contiguous United States. Source points were chosen based on the description of the native range given in Froese and Pauly (2018); no georeferenced observations were available to use. The certainty of this assessment is low. The overall risk assessment category in uncertain.
