The diversity and condition factor of fish species of Dadin Kowa Dam were studied over a period of six (6) months (February to July, 2013). Out of the fifteen fish species identified, family Mormyridae had the highest number of three (3) species, followed by families Bagridae and Characidae with two (2) species representing each. Hydrocynus brevis (family Characidae) ranked 22.14%, then Labeo senegalensis (family Cyprinidae), Mormyrus senegalensis (family Mormyridae), Schilbe mytus (family Schilbedae) with 17.40%, 17.01% and 13.05% of the total fish species identified. 60% of the fish species identified had their condition factors within the range of 0.1 to 1.0; whereas the remaining 40% of the fish had the condition factor greater than 1.0. Adequate measures need to be taken into account as most of the landed catches were juveniles and sub-adult which could render the water body less productive in a near future.
