    This study investigated the effects of Jatropha gossypiifolia leaf extract (JGE) on the performance and immune response of African sharptooth catfish. Fish (6.43 ± 0.26 g, n = 450, 30/repli cate) were fed diets supplemented with 0, 0.5, 1.0, 1.5, or 2.0 g JGE/kg in triplicate for 84 days. Thereafter, the fish were injected with Aeromonas hydrophila and observed for 14 days. Fish fed 1.0–1.5 g JGE had higher (P < 0.05) weight gain, protein effi ciency ratio, and villi absorption area, with highest performance at 1.0 g JGE. All the fish fed JGE-supplemented diets had enhanced (P < 0.05) activities of glutathione-s-transferase and glutathione peroxidase, compared to fish fed control diet, while the variations in erythrocyte and leucocyte counts were insig nificant (P > 0.05). The post-challenge fish fed JGE- supplemented diets had higher lysozyme, phagocytic, and respiratory burst activities and survival than the control treatment
