Survival rates of C. gariepinus challenged with A. hydrophila (1.0 × 106 CFU/mL) after six weeks of exposure to different treatments. Control group showed progressive mortality reaching 40% by day fourteen, while Moringa leaves-treated group maintained 100% survival throughout the observation period. The Moringa seeds-treated group showed intermediate protection with 85% survival. Fish monitored for 14 days post-challenge
