The present study aimed to evaluate the effect of replacing fishmeal for hydrolysate fish protein (HFP) and biofloc flour (BF) in diet of marine shrimp Litopenaeus vannamei postlarvae (2mg). The present study aimed to evaluate the effect of replacing fishmeal for hydrolyzed fish protein (HFP) and biofloc flour (BF) in Litopenaeus vannamei postlarvae. The HFP used in the diets formulation were produced from fish industry waste and the biofloc used for BF production was obtained in cultivation tanks of a commercial shrimp farm. Feed for this phase was designed to be isoenergetic and isoproteic. This experiment consisted of six treatments with three replicates each, corresponding to the control treatment T0, using fish meal as the main protein source. The other treatments (T10, T20, T30, T40) were a gradual replacement of fishmeal by HFP and BF in the proportions of 10, 20, 30 and 40% respectively. In the experiment a commercial feed was used as external control. It was a 42 days assay. Shrimp survival was above 99% in all treatments. After statistical analysis to zootechnical parameters (final weight, weight gain, specific growth rate) shrimps fed with formulated diets had better results than the ones fed with commercial feed. Tested parameters had ideal points indicated by regression in levels ranging between 15 and 16% of fishmeal replacement by HFP and associated BF. In the present study we inferred that BF and HFP are potential ingredients to replace fish meal in diets for L. vannamei postlarvae.
