Pacific bluefin tuna (PBT) Thunnus orientalis larvae at 18 days post hatching (dph) (total length; 14.8±2.1 mm) were fed for 6 days on fertilized eggs, yolk-sac larvae of spangled emperor Lethrinus nebulosus at 1 or 3 dph, or a microdiet. After feeding, growth performance, feeding incidence and survival were evaluated. Feeding 3 dph spangled emperor yolk-sac larvae improved growth of PBT compared to the other feeds. Crude protein and essential amino acids contents in the 3 dph spangled emperor yolk-sac larvae were higher than those of the spangled emperor at 1 dph. This result suggests that yolk-sac larvae of spangled emperor at 3 dph are suitable for PBT larvae and improved growth would be due to their higher protein and essential amino acids contents. It was also observed that 40% of PBT larvae fed the microdiet, suggesting that casein peptide based microdiet is acceptable for PBT.
