Body elongated; greatest depth contained 5.5 to 9.3 and caudal peduncle depth 9.9 to 16.1 times in SL; head length 2.9 to 3.8, anal-fin base length 2.1 to 2.7, maxillary-barbel length 1.6 to 6.5 in SL; snout length 3.7 to 5.7, horizontal orbital diameter 7.6 to 19.2, least interorbital width 2.2 to 2.7 in HL. 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.
