Abstract The addition of carbohydrate stimulates biofloc growth and the latter improves
water quality and reduces the need for water exchange, while the flocculated
materials serve as natural shrimp feed. T his research aimed at comparing effects
of corn starch and molasses addition on the white leg shrimp (0.07 g/individual)
stocked indoor at 250 individual/m3, with aeration and lighting, and fed with 37% protein and CIN ratio of 12. Both corn starch and molasses additions resulted in low Total Ammonia Nitrogen levels. The amount of bioflocs in both treatments increased over time. In the molasses treatment the periphyton growth was higher at the end of the experiment and had higher crude protein content compared to corn starch. But the latter resulted in significantly higher growth rate, production, average weight of the shrimp, and lower FCR. Nitrogen retention in the corn starch treatment was greater than that in the molasses treatment.
