Soybean meal (SBM) remains a primary protein source in aquafeeds. This study investigated the potential of winged bean ( Psophocarpus tetragonolobus ) as SBM replacement diets for butter catfish Ompok bimaculatus juveniles (mean weight: 1.24 ± 0.23 g). A response surface methodology (RSM) optimized processing conditions to minimize antinutritional factors (ANFs) (WBM), resulting minimized tannin (4.14 0.018 mg/g at 40 min, 110°C), phytate (0.414 0.0009 31.67 104.5°C) and trypsin inhibitor activity (70.8 0.06% inhibition 20 90°C). Experimental containing 30% crude varying levels WBM substitution (0%, 25%, 50%, 75% 100%) were fed 70 days. Growth performance, measured by weight gain, was significantly higher 25% group p < 0.05) but not different from control 50% substitution. Quadratic regression analysis predicted an optimal inclusion level 15.10% maximizing gain. Survival rates did differ among treatments > 0.05). Feed utilization most efficient group. Haematological immunological parameters indicated improved fish health level. Flesh quality attributes, including texture profile analysis, pH antioxidant activity, superior compared other treatments. However, colour enhancement more pronounced (≥50%). While flesh suggested stress levels, showed values control. These findings suggest that can potentially replace up diets, offering promising alternative source. provides preliminary data on feasibility prospects utilizing O. diets.
