Clarias gariepinus is an invasive species worldwide, which has been introduced mainly by aquaculture, and its impact on native fauna is well documented. Three individuals of C. gariepinus were captured by an artisanal fisherman in the D’Una River Basin in Santa Catarina State, Brazil. This paper documents the first record of C. gariepinus in this area, indicating an additional spot of occurrence in Brazilian inland waters, and discusses the potential impacts of this introduction.
