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.
Hydrolycus scomberoides, commonly known as Payara, is a large carnivorous fish found
throughout the Amazon River basin in South America. A carrier of the Braga patagonica and
Brasergasilus mamorensis parasites, it is used as a gamefish, as a minor target for commercial
fisheries, and in the aquarium trade. H. scomberoides is available for purchase within the United
States. Information on the biology and distribution of H. scomberoides is not readily available.
No reports of introductions beyond its native range were found. The overall climate match for
the contiguous United States is low, with a high match in southern peninsula Florida. The overall
risk assessment for this species is uncertain.
