Description: Cape Provincial Museum, Albany Museum, Grahamstown, Natural History. Volume 19. Part 6. 29th April 1996. Stapled wraps, p305-p344. illustrated. 184mm wide x 240mm high. New unread copy. The distribution pattern of 44 alien and translocateed freshwater aquatic animals in Southern Africa (excluding Zimbabwe & Mozambique) are updated and reassessed. A comparison with 1988 records indicates the presence of two alien species not recorded in natural waters. The distribution of 5 species, previously recorded in catchments outside their native ranges have been extended into new catchments. The common carp Cyprinus carpio Linnaeus 1758 has invaded more catchments than any other species and its range has recently been extended into the Phongolo and upper Mkuze systems. The composition of alien species in each major catchment and the catchments invaded by individual alien species are documented. Certain waterbodies of high conservation status (Okavango, Lake Sibaya and the Mkuze swamps) in sub-tropical regions are free of alien fish. It is recommended that special measures be taken to prevent introduction of alien species into these systems. Potential introductions through interbasin transfer schemes are also discussed.
