Africa: Lower
Zambezi, Lower Shiré and coastal plains from Zambezi delta
to Algoa Bay. Occurs southwards to the Brak River in the
eastern Cape and in the Transvaal in the Limpopo system.
Widely introduced for aquaculture, but escaped and
established itself in the wild in many countries, often
outcompeting local species. Several countries report adverse
ecological impact after introduction. |
