Abstract:Studies of the riverine fishes of the Ragati-Sagana-Tana Rivers drainage system in Kenya has lagged behind since the last comprehensive surveys of the 1950's and early 1960's, thus the purpose for the present study. A total of 30 riverine fishfamilies, which consist of 46 genera and 60 species occur in the drainage system. Thirty-seven (37) of these species arestrictly of freshwater origin, while 23 species are of marine origin. Four (4) of the freshwater fish species were introduced.The three most speciated riverine fishes in the system belong to the families Cyprinidae, consisting of eight (8) species, Mochokidae, consisting of five (5) species and, Gobiidae, consisting of four (4) species. The occurrence in the entire drainage system of one snoutfish species, Mormyrops anguilloides is uncertain. The use of the information from the present findings is highly recommended in carrying out further studies about fishes from the Ragati-Sagana-Tana Rivers drainage system. The knowledge is beneficial to fisheries managers, students of fish taxonomy, museumcurators and researchers of African fishes. (Source: Author Abstract)
