Mouth terminal with dentigerous tooth plates in both premaxilla, vomer and dentary. Dorsal fin with 61- 79, pectoral fin with I,9-12, pelvic fin with 6 and anal fin with 45-60 rays ( Hanssens, 2009). Ground color grey to yellowish, abdominal region white.

Maximum standard length. 700.0 mm.

Biological data. Lives in lakes, rivers and seasonally swampy areas ( Winemiller, Kelso-Winemiller, 1996). Feeds on plant material, plankton, arthropods, mollusks, fish, reptiles, and amphibians ( Yalçin et al., 2001).

Distribution. Africa and Asia Minor; introduced elsewhere ( Eschmeyer et al., 2017).

Remarks. Clarias gariepinus  , native of Africa, has been captured in the upper rio Paraná floodplain since 2005 by Nupélia staff. Its occurrence in the region can be associated with fish-farming and escapes from recreational angling ponds.
