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.
Pangasius macronema is a species of catfish native to Southeast Asia. It is found in the Mekong and Tonle Sap river basins in Thailand, Laos, Cambodia, and Vietnam, as well as on the islands of Sumatra, Java, and Borneo. P. macronema is one of the main fisheries along the lower Mekong, providing economic security to villages in that area. The history of invasiveness is no known nonnative population. No records of introduction were found. Therefore, there is no information on impacts of introduction. No evidence of trade of the species outside its native range was found. The climate match was low. There were areas of medium match in southern Texas and Florida. Texas had a medium individual climate score. The certainty of assessment is low. The overall risk assessment category is uncertain.
