This study focused on the assessment of Terminalia suparba (bark, leave and root) based diet to improve the ovulation of Clarias gariepinus brood stocks. Ten female and ten male brood stocks were obtained from a reputable fishfarm in Ogun State, Nigeria and were fed with the diets for four weeks before the breeding exercise. The latency period observed in treatments 1 to 4 was 4hours 30minutes while the ovulation period in treatment 5 was 8 hours. There was no significant different (P〉0.05) among the means. The brood stocks in Treatment 2 (Root) has the highest fecundity count (2001) while those in Treatment 5 (control) has the least fecundity count (1496). The phytochemical analysis of the plant materials showed the presence of Alkaloids, Tannin, Phenol, Glycoside, Flavonoids, Steroids, Phlobatannin, Saponin, Anthraquinones. The physical and chemical parameters of water observed showed that dissolved oxygen value ranges from 3.28 -4.60, pH 6.5 - 8.5, temperature 28.0 - 28.8 and conductivity 8.9 - 9.20. It is therefore concluded that the inclusion of Terminalia suparba in the feed of Clarias gariepinus broodstock will not only improve ovulation but also reduce the latency period.
