Author(s): Nazeef Suleiman, Idris Ado Yola and Ibrahim Muhammad Ahmed
Abstract: An assessment of the biodiversity and condition factor (K) of fish species from Challawa Gorge Dam was carried out over a period of six months (March-August, 2017). A total of ten (10) species representing nine (9) families were identified under the families Bagridae, Alestidae, Cichlidae, Claridae, Claroteidae, Latidae, Mochokidae, Mormyridae and Schilbeidae. Families Cichlidae and Mormyridae had the highest representation in terms of species and number of individuals. Assessment of the condition factor (K) showed that the family Mormyridae had the highest K values, followed by family Cichlidae. Schilbeidae had the least K values. However, the entire K value showed a 50% below and 50% average condition factors of fish. The dam has a rich ichthyofauna complex. Effective exploitation measures should be used to deter the menace of local extinction in the near future.
