Brazil is a country that presents favorable conditions for the creation of aquatic organisms, such as abundance of water resources and tropical climate. Fish farming is an agribusiness activity practiced in all the states of the Federation, differing in relation to the species, production systems and volume produced, and has shown a constant growth. The challenge of aquaculture research is to improve productivity, confidence and consistency of production data, and improved financial return on investment through more efficient use of water in production systems. Thus, technologies aimed at reducing water use in aquaculture production means become attractive, such as Biofloc Technology (BFT- "Biofloc Technology"). This ecological farming technique aims to increase production and profit, producing with the minimum water exchange and is based on the production of microorganisms in situ, which assimilate N ammoniacal and transform into microbial protein that will be consumed by the fish, recycling nutrients and maintaining the desirable levels of water quality. In addition, the bioflocs can be consumed and provide a significant fraction of the protein required by the animal, reducing feed costs. The present work evaluated the performance of tambaqui juvenile submitted to feed restriction and cultivated in the biofloc system (Biofloc Technology - BTFs).
