Ecological Risk Screening Summary - Giant Trahira (Hoplias lacerdae) - Uncertain Risk

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.

Hoplias lacerdae is an erythrinid fish species native to southeastern Brazil and Uruguay. It has been introduced to several other locations in Brazil for commercial fishing and aquaculture. H. lacerdae is suspected of being partially responsible for declines in some native fish species in locations where it has been introduced. However, no clear evidence has been documented that particularly implicates H. lacerdae as opposed to other introduced piscivores. Climate match to the contiguous U.S. is high, with the area of highest match occurring in the Southeast U.S. Overall risk posed by H. lacerdae is uncertain.
