This study aimed to evaluate the effect of the gradual replacement of fishmeal with fish protein hydrolysate ( FPH ) and biofloc flour ( BF ) in the diets of white shrimp L itopenaeus vannamei postlarvae (2 mg). Five diets (420 g kg −1 of crude protein) were formulated, and these replaced 0 (control), 10, 20, 30 and 40% ( T 0, T 10, T 20, T 30 and T 40, respectively) of the fishmeal. A commercial diet was used as an external control. The alternative ingredients FPH and BF were added at a ratio of 1 : 1. After 42 days, the shrimp survival was higher than 99% in all the treatment groups. A regression test indicated that the ideal fishmeal substitution level to obtain optimal zootechnical parameters (final weight, weight gain and protein efficiency) is between 15.16 and 16.5%. In this study, we demonstrated that BF and FPH are potential ingredients that can be used to replace fishmeal in L . vannamei postlarvae diets.
