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.
Xenentodon cancila, Freshwater Garfish, is a fish native to tropical Asia, from Pakistan to the Mekong River in Southeast Asia. It is used for human consumption in Asia, and in the aquarium trade in the United States. X. cancila has been introduced to and become established in Hawaii, likely as a result of the aquarium trade or aquarium releases. There is little information available on the impact of this species’ introduction to Hawaii. It may have threatened the non-native largemouth bass fishery there at one time. History of invasiveness is classified as “none documented.” X. cancila has a medium climate match with the contiguous United States, with the area of highest match located in southern Arizona and southeastern California. Certainty of this assessment is low due to a lack of information on impacts of introduction. The overall risk assessment category is uncertain.
