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.
Blue Tiger Piranha (Serrasalmus gouldingi) is a species of piranha native to the Amazon and Orinoco River basins of northern South America. It is sometimes found in the aquarium trade, although its trade status in the United States is unclear. Many States prohibit the possession or trade of piranhas. The history of invasiveness is uncertain. S. gouldingi hosts numerous monogenoid parasites within its native range. Climate match is consistently low across the contiguous United States. Due to lack of information, the certainty of assessment is low. The overall risk assessment category for S. gouldingi is uncertain.
