The objective of this work is to determine a basic reference diet for the larvae stage of "peixe-rei". Therefore, 600 individuals where utilized, with 7 days of age, distributed in 4 treatments with 3 replications, with varying levels of protein. Results show that the observed survival of 14 to 16 % is too low when compared to the 80% that are mentioned for larvae fed zooplacton, implying difficulty of adaptation of larvae t´o artificial food. In relation to diet effects na increase in growth was observed in length, as well as in weight, between the levels of 45 and 53 % of crude protein and 3,500 and 3,600 Kcal/kg of digestible energy, which did not occur in the 56 % level of crude protein and 3,700 Kcal/kg of digestble energy.  aCrescimento  aLarva  aPeixe rei  aProteina1 aPOUEY, J.L.F.  tIn: SIMPOSIO BRASILEIRO DE AQUICULTURA, 11.
