Abstract

A total number of 298 specimens of Nile Tilapia (O. niloticus) were collected from the southern part of Jebel Aulia Dam Reservoir during the period November 2012 to July 2013. Length-weight relationship and condition factor were determined for O. niloticus with the regression coefficient ‘b’ = 3.03357 indicating isometric growth pattern. Mean values of condition factor (K) ranged from 2.97-3.94 for the combined sexes, and varied monthly from 2.18 to 3.65, reflecting good condition and well-being of the fish.The results can be used to fill a gap in the knowledge about this species and provide useful information in the management and conservation for this popular food fish species in the White Nile waters in Sudan.
