The Length-weight relationship of four fish species from Doma dam were investigated in this study. Samples of Hydrocynus breves, Alestes dentex, Hydrocynus, Forskali, and B. leuciscus were collected from landing sites and the corresponding weight and length recorded. Result obtained revealed a negative allometric growth pattern for all the fish studied with ‘b’ value below 3, only A. dentex had ‘b’ slightly above 2 while others had values below previously specified ranges of 2-4. However, higher condition factors were observed for B. leuciscus compared to the other species reported in this study.
