A successful management of floodplain fisheries, such as in the Caprivi Region in Namibia, depends on a good understanding of the fish migrations and habitat preferences in these complex and variable ecosystems. Therefore, studies of the movements and habitat utilisation of radio tagged fish in the Upper Zambezi River were initiated by the Namibian Ministry of Fisheries and Marine Resources in 1999. The movements and habitat utilisation of tigerfish (Hydrocynus vittatus Castelnau, 1861), nembwe (Serranochromis robustus Günther, 1864) and threespot tilapia (Oreochromis andersonii Castelnau, 1861) were studied in 2000/2001, and the species specific results have been presented in three previous reports. The three species were studied in the same area of the river during the same period, and the results are therefore comparable.
