Ecological Risk Screening Summary - Bristlenosed Catfish (Ancistrus temminckii) - 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.

Ancistrus temminckii is a loricariid catfish native to Central and South America. The species was introduced to the island of Oahu, Hawaii, in the 1980s. It is now abundant in several water bodies on Oahu and is suspected of competing with native gobies, but data on species interactions are lacking. Climate match to the contiguous U.S. is medium, with highest climate match occurring in southern Florida. Overall risk posed by A. temminckii is uncertain.
