Length-Weight relationship was studied in Oreochromis niloticus niloticus, for a period of nine months from September 2012 to May 2013. The slope value (b) estimated for O. niloticus niloticus of both sexes was found to be 2.3133. The regression equations calculated for female was Log W = -3.4168 + 2.3133 Log L. The correlations coefficient was found to be significant (P<0.01). The significant difference between sexes of the species ‘F’ value was at 1% level. The b value differed from the ideal cube law of ‘3’ as is with the case of length-weight relationship studied in this species else where. The slope value was compared here could be very useful for comparison with the tilapia species in other geographical locations.
