In the nursery experiment, postlarvae with an average weight of 0.024±0.01g were stocked at 1200m−2 and shrimp with an average weight of 4.09±0.51g and stocking density of 300m−2 was used in the grow-out. The carbon sources used in the nursery were molasses (M) and rice bran (R) and in the grow-out were dextrose (D) and rice bran (R). In the nursery experiment, using molasses, the ammonia concentration was significantly lower (p<0.05). In the grow-out experiment with dextrose, the ammonia concentration was significantly lower (p<0.05), but performance data were significantly better (p<0.05) in the rice bran treatment. The faster degradation of dextrose and molasses sources may have provided higher levels of carbon as a substrate for heterotrophic bacteria to use in metabolizing ammonia, thereby improving the water quality.
