The present study was carried out in the Reserve of Fauna and Flora of Haut- Bandama in order to provide data on fish diversity and conservation status in this reserve subjected to high anthropization. For this purpose, experimental samplings were conducted using sets of gillnets, traps and dip nets from February to April 2017. As results, 31 fish species belonging to 17 families and 8 orders have been identified. The most prolific orders were Perciformes with 4 families and 9 species followed by Characiformes counting 3 families and 6 species. Cichlid fishes were more numerous with 6 species followed by families of Alestidae and Mormyridae. The most abundant species in the catches were Brycinusmacrolepidotus (38%), Brycinusimberi (31%), Chromidotilapiaguntheri (14%) and Oreochromisniloticus (7%). The diversity index of Shannon-Wiener was 2.8 and the evenness 0.54. These indices values were lesser than those registered before anthropogenic aggression. The conservation status of 5 species (16%) was Not Evaluated against 26 species that had the status of Least Concerned (LC) and they represented 84% of the fish community.
