Clarias nieuhofii • Clariidae • Cat-eLog

Cat-eLog Data Sheet
Scientific Name	**Clarias nieuhofii** Valenciennes, 1840
Common Name(s)	None
Type Locality	Indies.
Synonym(s)	Clarias gilli, Clarias pentapterus
Pronunciation	klar ee ass
Etymology	Clarias: From the Greek chlaros, meaning lively; in reference to the ability of the fish to live for long periods out of water.
Species Information
Size	500mm (19.7") SL. Find near, nearer or same sized spp.
Identification	Clarias species are characterized by having an elongated body; a soft rayed dorsal fin extending to, or nearly to, the caudal fin base; a soft rayed anal fin extending from just behind the anus to the caudal fin base; pectoral fins each with a serrated anterior bony spine; head depressed, covered largely by firmly sutured, surface sculptured bony plates forming a protective helmet; four pairs of flagellate barbels (nasals, maxillaries, inner and outer mandibulars); air breathing organs derived from the 2nd and 4th epibranchials within a superbranchial chamber.
Sexing	The genital papilla, which is to the right of the anus as you look at the fish with its head to the left, is elongated and pointed in males while it is round and relatively larger (and larger than the anus) in females. In ventral view especially, females are much broader in the body than males of equal age and rearing practices.
