Test diets for Nieuhofii’s catfish were supplemented by di-calcium phosphate at 0.2-1.3% available phosphorus, AvP. Feeding trial was undertaken in 0.55-0.56 g average body weight Nieuhofii’s catfish for 8 weeks. It found that the highest average body weight and weight gain was found in the fish fed 1.3% Avp di-calcium phosphate (p < 0.05). Survival, feed conversion, moisture, lipid and ash in fish body were not significantly different among treatments (p > 0.05). Protein content in the fish fed all di-calcium phosphate supplemented diets were higher than the control (p < 0.05). Diet with 1.3% Avp di-calcium phosphate supplementation resulted in higher protein retention compared to the control fish (p < 0.05). The highest lipid retention was also found in fish fed 1.3% AvP of di-calcium phosphate diet (p < 0.05). It was concluded that supplementation of 1.3% AvP di-calcium phosphate gave beneficial effects on growth, protein and lipid retention in Nieuhofii’s catfish.
