Abstract
The research on effect of mixed feeding schedules with varying dietary protein levels on the growth of hybrid catfish fingerlings was conducted with four treatments: (NT1-control) 7 days 30% protein continuously, (NT2) 6 days 30% + 1 day 20% protein, (NT3) 5 days 30% + 2 days 20% protein, and (NT4) 4 days 30% + 3 days 20% protein diet. The result shows that the highest growth and the lowest feed rate were observed in NT1 treatment, and not significantly different from those results of NT2 and NT3 (p>0.05). The feed cost for 1 kg of fish of NT3 treatment was lowest and 6.12% lower than that of NT1 treatment. Therefore, the best mixed feeding schedule for hybrid catfish is 5 days 30% + 2 days 20% protein diet.
