Comparative racial studies were carried out among these species using multivariate analysis of 9 morphometric characters and 9 meristic counts of 100 specimens for each species from each lagoon. The results showed that the 2 species from the 2 lagoons were phenotypically separable populations with some levels of divergence in morphometric characters. The data were analysed using independent sample t-test after allometric test revealed significant differences (P &lt; 0.05) in body depth, caudal peduncle depth and number of gill rakers in <em>Sarotherodon melanotheron</em> while vertebrae, caudal peduncle depth and right gill raker counts in <em>Tilapia guineensis</em>, which could have occurred as a result of environmental fluctuations, genetic diversity and differences in salinity in the 2 water bodies.</p&gt;}, number={1}, journal={Journal of Scientific Research and Development}, author={Kuton and B.
