Clarias gariepinus or African sharptooth catfish is a species of catfish of the family Clariidae, the airbreathing catfishes. Juveniles of African catfish, C. gariepinus were fed with different biowastes procured from various stations viz., slaughter houses, poultry sheds, fish markets, hotel kitchens and ware houses. Eya, Jonathan C. 1996. Contrary to other Clarias species, Clarias gariepinus has a high number of gill rakers varying from 24-110 (Ref. Joseph Eyo. Probably due to its resilience, and despite promising biological traits, some aspects of welfare are either disregarded or overlooked. Of the many Clarias species cultured, Clarias gariepinus has been subject to particularly intensive research; the species has been widely introduced for aquaculture outside its natural range.

Clarias gariepinus has also been introduced into most other countries in Africa, as well as several in Europe, Asia and South America. Its range has been extended by interbasin transfer schemes, anglers and aquaculture facilities (including hatcheries & farm dams) (Cambray 2003a) (Figure 3). Morphological aberrations of the pectoral fins in nine mating combinations involving Clarias gariepinus (Burchell, 1822), Heterobranchus longifilis (Valenciennes, 1840) and their hybrids were investigated to determine the level and genetic basis of occurrence. Lethal and sub-lethal effects of copper on Clarias gariepinus were studied using a 96-hour static bioassay.
