Experimental fisheries carried out in August 2019 made it possible to report the presence of a species of freshwater fish, Mudfish Clarias anguillaris (Linnaeus, 1758) (Siluriformes Clariidae), to Guelta Ifni (Illizi) an integral part of the Tassili N'Ajjer National Park (south-eastern Algeria ).This species is on the IUCN red list as Least Concern (LC) being a taxon that does not qualify for Critically Endangered, Endangered, Vulnerable or Nearly Threatened.Surveys of 16 morphometric variables and three meristics, representing specific distinguishing characteristics, established on two male specimens, confirm this determination.This new locality will complete the current inventory of freshwater species reported in southern Algeria as well as the mapping of the distribution of the species in the in the African continent.
