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 Olive Barb (Systomus sarana) is a freshwater fish, native to Southeast Asia, found in Afghanistan, Pakistan, India, Nepal, Bangladesh, Bhutan, Sri Lanka, Myanmar, and Thailand. S. sarana is a popular food and aquarium species. Populations of this species have been declining. This species can be infected with epizootic ulcerative syndrome, which is an OIE-reportable disease. Systomus sarana have not been reported as introduced anywhere outside of their native range, leading to an uncertain history of invasiveness. The climate match for the contiguous United States is medium. Most of the contiguous United States had a low climate match while medium to high matches were located in southern Florida and southwestern portions of the country. The certainty of this assessment is low due to lack of information. The overall risk assessment of Systomus sarana is uncertain.
