The role of carcass evaluation techniques in aquaculture genetics and breeding cannot be over-emphasized. Knowledge of growth potentials concerning carcass quality has improved genetic selection techniques and management. Therefore, this study was conducted on the carcass yields, by-yields, anatomical separation, and nutritional quality of Clarias gariepinus strains collected from river Rima and two other population groups from two different fish farms with records of a pure cultured strain of C. gariepinus and another farm with a pedigree of artificial crosses. The flesh weight (FW) of the river Rima (55.50±2.97) population strain was higher (p
