C
starts withThe African sharptooth catfish is a large, eel-like fish, usually of dark gray or black coloration on the back, fading to a white belly. In Africa, this catfish has been reported as being second in size only to the vundu of the Zambesian waters, although FishBase suggests the African sharptooth catfish surpasses that species in both maximum length and weight.
C. gariepinus has an average adult length of 1–1.5 m (3 ft 3 in – 4 ft 11 in). It reaches a maximum length of 1.7 m (5 ft 7 in) TL and can weigh up to 60 kg (130 lb). These fish have slender bodies, flat bony heads, notably flatter than in the genus Silurus, and broad, terminal mouths with four pairs of barbels. They also have large accessory breathing organs composed of modified gill arches. Also, only the pectoral fins have spines.
They are found throughout Africa and the Middle East, and live in freshwater lakes, rivers, and swamps, as well as human-made habitats, such as oxidation ponds or even urban sewage systems.
The African sharptooth catfish was introduced all over the world in the early 1980s for aquaculture purposes, so is found in countries far outside its natural habitat, such as Brazil, Vietnam, Indonesia, and India. In countries where native species of Clarias occur, such as Indonesia, the sharptooth catfish may be distinguished; In Indonesia, it is referred to as lele dumbo.
It is a nocturnal fish like many catfish. It feeds on living, as well as dead, animal matter (such as insects, plankton, snails, crabs, shrimp, other invertebrates, birds, reptiles, amphibians, small mammals, other fishes, and eggs) and plant matter such as fruit and seeds. Because of its wide mouth, it is able to swallow relatively large prey whole. It has been known to take large waterbirds such as the common moorhen. It is also able to crawl on dry ground to escape drying pools. Further, it is able to survive in shallow mud for long periods of time, between rainy seasons.
African catfish sometimes produce loud croaking sounds, not unlike the voice of the crow.
