Abstract
The growth of aquaculture industry is on the rise as the world"s population grows and food sources become scarce. However, the increase in aquaculture faces environmental problems due to polluted effluent. Therefore, the aquaculture industry is actively developing biofloc technology (BFT), an eco-friendly aquaculture method. This study analyzed the water quality characteristics during biofloc formation for 30 days (1, 3, 6, 12, 18, 24, 30 days). As a result, changes in color (light brown → dark brown) and foam on the water surface were observed over time. Peaks of ammonia (5.7 mg/L, 1 day), nitrite (3.4 mg/L, 6 days) and nitrate appeared as a sequence (60.1 mg/L, 12 days), and it was confirmed that water quality stabilization occurred 24 days after cultivation. In addition, changes in the amount of floc in the water quality (34 mL/L, 1 day → 2 mL/L, 12 days → 6 mL/L, 18 days) and TSS change occurred using the Imhoff cone, and the floc size changed (73,481 μm², day 1 → 1,838 μm², day 12 → 9,940 μm², day 24). These results will provide data on dynamics of water quality during the biofloc formation process in freshwater, and may help understand biofloc formation in using BFT.
