Resumo: | ABSTRACT The present study investigated marine yeast as a food source in the Pacific white shrimp Litopenaeus vannamei. Yeast absorption efficiency was determined by measuring the proportion of organic matter assimilated by shrimp post-larvae (PLs). The yeast was isolated and propagated in the laboratory from a sediment sample obtained from a mangrove mudflat. Shrimp post-larvae at six stages, from PL-5-days-old to PL-35-days-old were fed exclusively with yeasts, at three concentrations (1.5 × 105, 3 × 105, 5 × 105cell/mL). The overall average of yeast absorption was around 65.85 ± 11.42 %. The two-way analysis of variance ANOVA (p &lt; 0.05) showed that the efficiency of yeast absorption was not affected by the concentrations of yeasts as a food source: none of the yeast concentrations interacted with the age of the post-larvae. The absorption efficiency of 67.30 % registered in young post-larvae (PL 5-days-old to PL15-days old) was significantly different than the efficiency registered for older post-larvae (PL 20 days old to PL 35 days-old) with an average of 60.21 % (p &lt; 0.05). The relatively high absorption efficiency of yeast in L. vannamei post-larvae contributes to a better understanding of the potential role of microorganisms as complementary feedstuffs in coastal aquaculture.
