oa Madoqua - The effect of the artificial linkage between the Kunene River and the Cuvelai system on the fish fauna in Owambo, Namibia
A concrete canal, built in 1972 to supply water from the Kunene River to the central parts of Owamboland, is responsible for the transfer of 32 fish species from the Kunene River to Owambo. Most of these fish are at present limited to artificial reservoirs. Only one cichlid species has so far succssfully invaded the oshana system. Turbidity is believed to be the main factor preventing the invasion of Kunene River fish into the oshanas.
