Resumo: | Newly-hatched grouper larvae were reared for 24 days at a density of 15 larvae.l&lt;sup&gt;-1&lt;/sup&gt; in 250-l capacity cylindro-conical tanks filled with 200l seawater. Starting day 2, the larvae were given: &lt;i&gt;Chlorella&lt;/i&gt;-fed rotifers (Chl-R) rotifers fed Culture Selco (INVE Aquaculture NV, Belgium) (CS-R), and rotifers fed Culture Selco and consequently enriched for 24h with 20% vitamin C (CSC-R). The rotifer density in the larval tanks was maintained at 15 rotifers.ml&lt;sup&gt;-1&lt;/sup&gt;. The rotifer diet was supplemented with egg yolk until day 5. Each treatment had five replicates. Preliminary results show no significant difference in the survival rate of grouper larvae given Chl-R (4.21±2.8%), CS-R (2.56±0.9%) and CSC-R rotifers (1.89±1.5%). The total length of larvae given CS-R (9.74±1.2mm) and CSC-R rotifers (9.62±1.4mm) were significantly different (P&lt;0.05) when compared with larvae given Chl-R rotifers (8.39±1.13mm). Likewise, the wet weight of the larvae fed CS-R (7.23±2.75mg) and CSC-R rotifers (7.29±3.02mg) was significantly different (P&lt;0.05 from those fed Chl-R rotifers (3.26±1.66mg). The difference in growth between CS-R and CSC-R fed larvae was not significant. Additional runs will be conducted to verify the results of this experiment.
