The specimen was collected in February/2016, and was evaluated showing dubious characteristics indicating the possibility of the occurrence of hybridization. Thus, fin specimen fragments were sampled and the genetic analyzes were performed. Our results indicated that the studied sample had a heterozygous electrophoretic profile revealing itself as a hybrid between Piaractus brachypomus and Colossoma macropomum being the second species the maternal parent.
