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.
The Giant Pangasius (Pangasius sanitwongsei) is a species of large catfish native to the main river drainages in southeastern Asia. The species has been heavily fished for local consumption and the aquarium trade by local peoples. P. sanitwongsei is now considered rare and threatened in part due to the intense harvesting. It is cultured and stocked in the wild by the Thai government. The history of invasiveness for this species is no known nonnative population. A single record of introduction was found in South Africa. Only a single specimen was collected and no information indicating an established population at that location could be found. This species is in the aquarium trade, particularly as juveniles. The overall climate match was low. The southern areas of Florida and Texas had medium matches but all States had low individual Climate 6 scores. The certainty of assessment is medium. The overall risk assessment category is uncertain.
