Giant river prawn (Macrobrachium rosenbergii) is one of the most imperative aquaculture species in many countries in Asia and in several American countries such as Brazil, Mexico and United States. Nursery rearing of M. rosenbergii postlarvae is an intermediate phase between larval rearing and grow-out culture. This practice ensures advanced size postlarval prawns are supplied to grow-out farmers for better survival. Advanced postlarvae also enables the grow-out farmers to obtain three crops in a year. A biofloc technology (BTF) system might be an alternative environment friendly technique in nursery operation practice of M. rosenbergii as it can improve water quality conditions, provide instant food, nutrition and health care to the culture animals. Biofloc contains proteins, lipids, minerals, vitamins, amino acids, and fatty acids as well as enzymes, immunostimulants and probiotics. Typically, crustaceans are well adapted to consume bioflocs, including M. rosenbergii. Different carbon sources such acetate, corn starch, glycerol, molasses, rice bran and others have been used to develop the biofloc system. The results of this study indicated that the giant river prawns could be successfully raised using BFT system during the nursery stage. The use of maize starch as carbon source allowed higher growth, better survival (86.6%) and FCR (2.21), net income and benefit-cost ratio.
