Objective: A study was done to characterize the erythrocyte of triploid African catfish. Methodology: Triploid African catfish Clarias gariepinus fingerlings were produced via cold shock method and their erythrocyte profiles were compared with normal diploid controls. Results: Approximately 99% of triploid erythrocytes were ellipsoidal whereas 97.5% of the diploid erythrocytes were round in shape. All of the erythrocyte parameters showed significant higher values in triploids and exhibited size range exclusive to triploids except erythrocyte cellular volume. The nuclear volume and nuclear area were among the two erythrocyte parameters that showed the largest increment in triploids (76.6 and 55.3%, respectively) with their respective exclusive triploid range at 74.3-150.2 and 22.8-35.2 :m. Both erythrocyte and nuclear major axis increased at a much higher percentage with respect to erythrocyte and nuclear minor axis in triploid specimens, resulting in the ellipsoidal shape of triploid’s erythrocytes. The erythrocyte major axis also has the highest percentage (76.0%) of erythrocytes that fall in the exclusive triploid range (11.9-14.9 μm) compared to the other erythrocyte parameters. Conclusion: Therefore, it is suggested that determination of triploid African catfish can be performed solely based on the measurement of erythrocyte major axis.
