This species is generally common and widespread. In Lake Kariba on the Middle Zambezi River, its population fluctuated considerably, mostly in relation to the abundance of the introduced clupeid Limnothrissa miodon which now forms a major part of its diet (Kenmuir 1973, Marshall 1985). It is commercially exploited in Lake Rukwa, forming about 3.9% of the yield. In Mtera dam, species composition in the catches show a decline from 26.1% in 1987 to 14.3% in 1991, and 7% in 1996.
