Abstract Implementation of biofloc technology (BFT) system in aquaculture industry shows high productivity, low feed
conversion ratio, and an optimum culture environment. This study was divided into two phases. The first phase
involved maintaining the water quality using the optimum carbon-to-nitrogen ratio by manipulating pH in culture water. The second phase examined the performance of harvesting biofloc (remaining phytoplankton and suspended solids in the system) using chicken eggshell powder (CESP). This study showed that pH 7 to 8 were the
best biofloc performance with high removal percentage of ammonia (>99%) with a remaining ammonia concentration of… More >
