Abstract: Influence of microalgal feeding with <i>Isochrysis galbana </i>and <i>Chlorella</i> sp. on the growth and survival rate of larvae of European flat oyster, <i>Ostrea edulis,</i> was investigated<i>.</i> Larvae were reared with four food regimes: <i>I.</i><i> galbana,</i> <i>Chlorella</i> sp., mixture of both and unfed for 16 days. After 16 days, it was observed that the larvae reached the umbo stage with a mean size in length 220±4.12 µm and 219±5.76 µm (initial length, 159 µm) (P > 0.05). Larvae were fed on <i>I.</i><i> galbana </i>and mixture diet. At this stage, survival rate was 30% and 24%, respectively (P > 0.05). Growth and survival rates for the feeding regimes were significantly higher than the <i>Chlorella </i>sp. and unfed groups (P < 0.05).
