Microbial aggregates derived from the biofloc system serve as a supplemental feed source, contributing to weight gain in animals and maintaining water quality in the culture system. Through this nutritional input, diets formulated for BFT systems with lower protein levels than typically used may be sufficient to meet the animals' nutritional requirements, provided the culture duration is respected and there is no impairment of zootechnical performance. Therefore, the objective of the present study was to evaluate water quality and the zootechnical performance of Litopenaeus vannamei fed commercial diets with different protein levels formulated for super-intensive systems. The experiment was conducted in eighteen 150 L tanks, with nine tanks using clear water and nine using biofloc. Each tank was stocked with 75 animals, and the total experimental duration was 42 days. The three treatments differed in the use of three commercial diets produced by Guabi® Nutrição e Saúde Animal (Campinas, São Paulo, Brazil), namely: BFT 30, BFT 35, and Active 40 (control). At the end of the experiment, water quality parameters were analyzed and remained within the expected range for both the clear water and biofloc treatments. The zootechnical performance of the shrimp did not differ (P > 0.05) among the diet treatments tested. This indicates that within biofloc environments, microbial communities can develop effectively with the different diets tested, and it is feasible to use a diet specifically formulated for biofloc systems with 30% crude protein, yielding satisfactory culture results.
