Background
The objective of the present study was to evaluate the growth performance and feed utilization of African catfish fed a commercial diet and Clarias gariepinus reared in the biofloc system enhanced with probiotic.
Methods
The treatment was the frequency of probiotic application into the cultured system, namely, 5-day interval, 10-day interval, and 15-day interval for 60 days of experiment. Biofloc culture was grown in an experiment tank (vol. 2000 L) by mixing the probiotic ( sp.) 10 mL and molasses 200 mL per liter of Bacillus water. The fish was stocked into the biofloc system 7 days after cultured at stocking density of 1000 fish tank. The fish was fed a commercial diet that contains 38% crude protein, twice a day at satiation. The application of probiotic was reperformed after 5 days, 10 days, and 15 days after stocking.
