Língua:

Ref. principal	Philippart, J.-C. and J.-C. Ruwet, 1982
Notas	Inhabit the littoral zone of lakes and are abundant in Lakes Turkana (Rudolf) and Albert. Although a freshwater species they are also found in brackish water like in the Nile Delta. The area occupied by the species extends from 8° S to 32° N and from 6000 ft (1830 m) to sea level. O. niloticus of Lake Edward form very large schools of 100 sq.m or more at the lake surface when feeding. The species takes epiphytic algae, diatoms or plankton according to conditions. (See also Ref. 3736).
