The aim of this study is to report the presence a three non-native hybrid long-whiskered catfishes (family Pimelodidae) in Upper Paraná River basin, Brazil. Genetic analyses demonstrated that presumptive hybrids were result crossbreeding Pseudoplatystoma reticulatum (central Amazonas basin and Lower River) Leiarius marmoratus (Amazonas, Essequibo Orinoco rivers), producing commonly known Brazil as cachandiá. potential threat biodiversity, due possible genetic contamination, competition predation wild stocks, such artificially produced fishes discussed.
