Studies relating regional fish species are relatively advanced in the reproductive aspect;
however, these species will only turn out viable for intensive cultivation and economically
profitable, with the formulation of adequate rations, accordingly to their feeding
characteristics, which allow satisfactory growth in relation to costs, time of cultivation and
quality of the final product. 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.
