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.
Dawkinsia filamentosa, the Blackspot Barb, is a small cyprinid fish native to India. It is used for local consumption and in the aquarium trade, including in the United States. This species was introduced to reservoirs in Hawaii in 1984 and then quickly extirpated, and no impacts of introduction were documented. History of invasiveness is uncertain. D. filamentosa has a low climate match with the contiguous United States. The southern parts of California, Arizona, Texas and Florida had a medium match. Certainty of this assessment is low because of a lack of information on impacts of this species’ introduction outside of its native range. Because of this, the overall risk assessment category is Uncertain.
