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.
Prochilodus lineatus is a freshwater fish native to parts of southern South America which has been introduced to Vietnam and China. This species is an important commercially harvested fish in its native range and is a popular aquaculture species in both its native and introduced ranges. Established populations have been reported from both Vietnam and China with sources suggesting these populations originated from aquaculture escapees. P. lineatus may be in trade in the United States. No information regarding documented impacts from introduction were found. The history of invasiveness is classified as Data Deficient. This species had a high overall climate match with the contiguous United States, with most areas of locally high match in the Southeast. The certainty of assessment for P. lineatus is Low mainly due to the lack of information regarding impacts of introductions. The overall risk assessment category is Uncertain.
