Overview

The aim of this study was to analyze the effects of production and economic viability of commercial diets with different protein sources associated with a 50% reduction of artemia in the feeding of Penaeus vannamei post-larvae. Four treatments were used in a completely randomized design, with four repetitions: T1—krill flour and salmon extract (78% CP + 50% reduction of artemia); T2—fish meal and mussel meal (70% CP + 50% reduction of artemia); T3—squid meal (63% CP + 50% reduction of artemia); and T4—canola meal (48% CP + 50% reduction of artemia). The commercial feeds were offered into 16 experimental units, for 18 days, from hatching to post-larvae harvest. Total number of larvae, survival, final weight, and biomass were analyzed by ANOVA followed by Tukey test. Greatest survival (51.47%) was achieved by the animals in T1. Biomass was higher in T1 and T2 (18.35 and 20.51 g, respectively) when compared to T3 and T4. We concluded that commercial feed consisting of quality marine protein and protein levels equal to or above 70% provide better zootechnical indexes and financial gains in P. vannamei hatchery, even with a 50% reduction in the supply of artemia.
