Ecological Risk Screening Summary - Peacock Eel (Macrognathus siamensis) - 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.

Peacock Eel (Macrognathus siamensis) is native to southeast Asia. M. siamensis is used in commercial fisheries and the aquarium trade. Established populations of M. siamensis occur in southern Florida. The source of the populations in Florida is believed to be an aquarium release. Impacts from the established population in Florida have not been documented. Introduction to the Philippines has also been reported, but it is unknown whether M. siamensis is now established there. Certainty of assessment is low because no studies of impacts were found. The climate match with the contiguous United States is medium. The overall risk for M. siamensis is uncertain.
