A total number of 365 individuals of the fish species were caught during the period of study with <em>Sarotherodon galilaeus</em> constituting 65.21% of the total catch while <em>Oreochromis niloticus </em>made up 34.79% of the catch. The mean weight (W) and mean total length (TL) were 56.04 ± 1.019 g and14.64 ± 0.103 cm respectively for <em>S. galilaeus</em>;62.86 ± 2.184 g and15.84 ± 0.171 cm respectively for <em>O. niloticus</em>. The values of constants <em>a </em>and <em>b </em>(growth exponent) were determined from the length and weight data which transformed into the linear equation of log W = log a + b log L. These parameters were then fitted to the exponential equation, W = [aL]<sup>b</sup><em>. </em>The respective exponential equation for the length-weight relationship was W = 0.068[L]<sup>2.5</sup> for <em>S. galilaeus</em> and W = 0.034[L]<sup>2.7</sup> for <em>O. niloticus </em>which shows that both species exhibited negative allometric growth (b &lt; 3.0). The correlation coefficient (r) and condition factor (K) recorded were 0.944 and 6.70 respectively for <em>S. galilaeus </em>and 0.911 and 3.49 respectively for <em>O. niloticus</em> specimens. The species showed negative allometric growth and were thriving well in the environment.</p>}, number={1}, journal={Notulae Scientia Biologicae}, author={AMOO, Timothy O. and KOMOLAFE, Olaniyi O.}, year={2016}, month={Mar.}, pages={21–26} }
