This paper reviews the history of exploration and the current state of knowledge of the fish species diversity in Ethiopia. It assesses this diversity in the six main drainage systems using original data on fish species composition at 135 localities, and published information. The number of indigenous species and endemics percent area as follows: 106 (12%) in White Nile system within the limits of Ethiopia, 64 (35%) in the Blue Nile System, 32 (none or few) in the Atbara-Tekeze system, 79 (19%) in the Omo-Turkana system (including Lake Turkana itself), 31 (19%) in the Ethiopian Rift Valley, and 31 (61%) in the Wabi Shebele-Juba system. The regions where the fish diversity is still poorly explored are indicated. The research and management problems that should be solved to aid the development of domestic expertise in exploring, assessing and identifying fish species diversity are identified and some conservational issues are discussed.
