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 Siamese Mud Carp, Henicorhynchus siamensis, is a small freshwater fish species native to the Mekong, Mae Khlong, and Chao Phraya basins in Southeast Asia. It is an important part of the diets of rural people in the species’ native range. There is no indication that this species is in trade in the United States. There are no reports of introductions. Therefore, history of invasiveness is uncertain. H. siamensis has a low climate match with the contiguous United States overall, and a medium climate match in southern Texas and peninsular Florida. Certainty of this assessment is low because of a lack of information about the invasive potential of this species. The overall risk assessment category is Uncertain.
