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.
Serrasalmus odyssei is a freshwater fish species native to Bolivia, South America. S. odyssei is reported from the clear- to black-water rivers of the Upper Madeira where it seems to be scarce in white waters. It inhabits the shallow part of the river near the shores especially where dead woods accumulate and is scarce in the running part of rivers. It is common in syntopy with young S. rhombeus individuals of equal size. No introductions for the species have been reported. Climate match with the contiguous United States is low overall. However, much of peninsular Florida has a medium match. More information is needed to fully understand the impacts from introductions of this species. Absence of this information makes the certainty of this assessment low. Overall risk posed by this species is uncertain at this time.
