Study of ichthyofauna of Daberam Reservoir, Katsina State

Research was carried out to explore the fish species diversity and study some aspects of the biology of fish of Daberam reservoir, Katsina state, Nigeria, for a period of three month from March to May 2009. Samples were collected from commercial fishermen and experimental fishing gears, preserved in formalin and taken to laboratory for identification; confirmation was done by fisheries experts. Eight genus comprising ten species were identified. The regression coefficient (b) was 3.07, 2.91 and 3.21 for the three most commercially importance species in the reservoir i.e. Oreochromis niloticus, and Clarias gariepinus respectively which indicated Positive allometric growth for O. niloticus and C. gariepinus and negative allometric growth for T. nilotica. The mean condition factor (k) was 1.140, with values of 1.027and 0.732 for O. niloticus and C. gariepinus, respectively. This indicates that the fish are not leaving well compared to other freshwater fishes.
