<![CDATA[Biofloc technology offers a promising strategy for improving production efficiency and environmental stability in intensive shrimp culture. This study evaluated the efficiency of a biofloc system compared with a conventional system based on the growth, feed utilization, survival, final body weight, and water quality of juvenile whiteleg shrimp (Litopenaeus vannamei). A quantitative experimental design was applied using two culture treatments, each consisting of three independent replicates. Juvenile shrimp with relatively uniform initial body weights were maintained for 60 days under standardized stocking density, feeding management, aeration, and culture conditions. The observed parameters included absolute weight gain, average daily growth, specific growth rate, final body weight, survival rate, feed conversion ratio, temperature, pH, dissolved oxygen, salinity, ammonia, and nitrite. Data were analyzed descriptively and comparatively using an independent-samples t test or Mann–Whitney U test according to data distribution. The biofloc system produced higher growth, final body weight, and survival than the conventional system while generating a lower feed conversion ratio. It also maintained higher dissolved oxygen and lower ammonia and nitrite concentrations. Temperature, pH, and salinity remained comparable between treatments. These findings demonstrate that biofloc technology can improve feed utilization, control nitrogenous waste, and provide more stable environmental conditions for juvenile whiteleg shrimp. Its application should be accompanied by careful management of aeration, carbon inputs, and suspended solids.  ]]>
