Moringa ( Moringa oleifera ) has frequently been studied as an alternative and promising protein source in fish feed. Moringa leaves is among the potential and affordable plant-based protein source ingredient, as it protein, vitamin, beta-carotene, and various kind of minerals. Flavonoid, saponin, vitamin and alkaloids reportedly exhibit immune-stimulating activity which increase immune response. This study aims to evaluate the replacement of fish meal with fermented Moringa leaves meal in feed on the immune response of red tilapia ( Oreochromis sp.). The research was conducted experimentally using a completely randomized design by four treatments in triplicate. The treatments include replacement of the fish meal with fermented moringa leaves meal at 0, 10, 20, and 30 %. Red tilapia with total length of 9 to 10 cm was fed twice daily for two months at a feeding rate of 3 % of total biomass. The results showed that replacement fish meal with fermented Moringa leaves meal as much as 20 % increases the percentage values of hematocrit and leukocrit, stimulates phagocytic activity and phagocytic index, suppresses monocyte and increases lymphocytes, and increases total plasma protein.
