This study was designed to assess and compare the
phenotypic variability among the population of Nile Tilapia
(Oreochromis niloticus) caught from rivers, Taraba and

obtained from the experiment were subjected to t-test at
95% confidence level (p=0.05) with the aid of IBM SPSS
version 25. The results revealed significant size-related
variation in the fish from the two different water
environments. There is significant differences were
observed in the 18 phenotypic parameters measured from
