Popis: ABSTRACTThis study aimed to optimize an extruded aquafeed for Oreochromis niloticus (Nile tilapia) using moringa as a partial protein source. Response surface methodology (RSM) with a Rotatable Central Composite Design (CCRD) was employed to evaluate the four factors influence: sardine meal (28.5–39.25%), moringa flour (34.85–45.60%), temperature (110–140°C) and moisture content (13–17%) on aquafeed’s physicochemical characteristics: expansion index (EI), bulk density, water solubility index (WSI), water absorption index (WAI), hardness and buoyancy. Numerical optimization identified 100 potential diets, of which four were selected and met the criteria for high WSI (11–14%), low hardness (22–32 N) and 100% buoyancy. The best diet consisted of 31.19% sardine meal and 42.91% moringa flour, processed at 132.5°C and 16% moisture, presenting 13.68% WSI, full buoyancy, 29.63 N hardness, 36.33% protein, 10.71% lipids, and 31.36% carbohydrates, applicable to fingerling O. niloticus.
