Research was carried out to explore the fish species diversity and study some aspects of the Biology of fish of Daberam reservoir, Katsina state, for a period of three month from March to May 2009. 66 Samples of fish were collected from commercial fishermen and experimental fishing gears, preserved in formalin and taken to laboratory for identification. Seven genera comprising eleven species were identified. The regression coefficient (b) were 3.07, 2.91 and 3.21 for the three most commercially importance species in the reservoir i.e. Oreochromis niloticus, Tilapia zilli and Clarias gariepinus respectively, the results indicated Positive allometric growth for O. niloticus and C. gariepinus and negative allometric growth for T. zilli. The mean condition factor (k) was 1.140, with values of 1.027, 1.660, and 0.732 for O. niloticus, T. zilli and C. gariepinus respectively. This result indicates that the fish are not leaving well compared to other freshwater fishes. Key words: Daberam reservoir, fishdiversity, allometric growth, condition factor
