We investigated the effects of taurine-enriched rotifers on larval growth and swim bladder inflation of yellowtail Seriola quinqueradiata. Rotifers were enriched with a commercial taurine supplement at two levels (0 and 800 mg/L). The larvae (initial notochord length=3.98±0.24 mm) were fed the enriched rotifers in triplicate from two days post-hatch for five days. The average taurine contents of the taurine non-enriched and enriched rotifers were 0.35±0.01 and 4.77±0.05 mg/g dry matter, respectively. The weight gain and specific growth rate of the fish fed enriched rotifers with the taurine supplement at 800 mg/L significantly improved compared with those of fish fed rotifers without taurine enrichment (P<0.05). The swim bladder inflation rate of larvae fed taurine enriched rotifers significantly (P<0.05). The results of the present study indicate that yellowtail larvae benefit from taurine concentrations compared with those typically reported to feed on non-taurine supplemented rotifers. Furthermore, taurine-enriched food for fish larval effectively improved the growth performance and swim bladder inflation of yellowtail larvae.
