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.
Osteochilus spilurus is a cyprinid fish native to Southeast Asia. This species has a low climate match with the contiguous United States. The area of highest match was in Florida and along the Gulf Coast. O. spilurus has not been reported as introduced outside its native range, so the history of invasiveness is uncertain. It is used in the ornamental trade in Malaysia and may be found in subsistence fisheries. It is reportedly extirpated from Singapore, where it was native. Because of a lack of information on which to base a risk assessment, the certainty of this assessment is low. The overall risk assessment category is Uncertain.
