Moringa oleifera is a highly nutritious and water purifier plant that is widely utilized in the aquaculture sector. Tilapia fish has various advantageous characteristics endowing it appropriate for aquaculture. Thus, this current study is designed to evaluate the impact of Moringa oleifera MOAE aqueous extract supplementation at the levels of 0, 100, 200, and 400 mg/kg diet for 3 months on Nile tilapia, Oreochromis niloticus. Antioxidant capacity, reproductive hormones, cytokines, and gonadal histological and caspase-3 immune-histochemical changes are assessed. Outcomes revealed a significant (P < 0.05) decrease in the antioxidant (CAT, SOD, GSH, and GPx) readings plus a significant (P < 0.05) increase in the proinflammatory cytokines (TNFα, IL1-β) was recorded for the 400 mg MOAE/kg group. In addition, significant (P < 0.05) improvements in estradiol and testosterone concentrations were detected in the 200 mg MOAE group. However, gonadal histological alterations were detected in the 400 mg MOAE/kg group, while the best histo-architectures were recorded for the 200 mg MOAE/kg group. Associated Caspase-3 immunoexpression showed wide-ranging positive three cells indicating severe apoptotic features for the 400 mg MOAE/kg group. Consequently, 200 mg/kg diet MOAE dietary supplementation is suggested for enhancing immune-antioxidant traits and reproductive hormones and modulating cytokines, as well as gonadal activity enhancement of O. niloticus with caution when the level of MOAE exceeds 200 mg/kg diet.
