Conservation: Australoheros perdi is not evaluated by the international union for the conservation of nature in the iucn red list of threatened species. One of the most serious problems in the Parque Estadual do Rio Doce is biological invasion. Only three lakes of the PERD do not contain introduced species. One of the lakes without introduced species is the Lagoa Gambazinho, habitat of Australoheros perdi and some species that have who disappeared in other lakes in the system that contain invasive species as peacock bass (Cichla kelberi Kullander & Ferreira, 2006) and the red piranha (Pygocentrus nattereri Kner, 1858). Thus, species of small and medium size, like A. perdi, are seriously threatened in this system invaded by alien fish species. (Compiled from Ottoni et al., 2011).
