The purpose of this study is to analyze the application of biofloc technology using male monosex larvae to the growth rate, survival rate, feed conversion ratio, feed efficiency, and water quality profile of red tilapia with different stocking densities. The method of this research was monosex red tilapia production (masculinization) using immersion of tilapia larvae aged 10 days after hatching using the hormone 17á-metiltestosterone at a dose of 2 mg/l, stocking density of 250 individuals/m3 at 36° C for 4 hours. Then the biofloc treatment with a density of 50 fish/m3 and 100 fish/m3 without biofloc and with biofloc C/N ratio 15. The results obtained that the pond with biofloc treatment has specific growth rate, average daily gain, feed efficiency, and survival rate higher than control. In addition it has a lower FCR value for biofloc treatment, especially in ponds with stocking densities of 100 fish/m3. In this study, ponds with biofloc treatment at 100 fish/m3 stocking densities gave the best results on aquaculture performance.
