Japanese sardine larvae <i>Sardinops melanostictus</i> hatched out from field-collected eggs, were successfully reared for 30 days with the survival rate of 13% of initial egg number. The relation between rearing days (<i>D</i>) and number of sagittal otolith rings (<i>N</i>) was expressed by the linear regression of <i>N=0.99D</i>-1.88 based on the 31 reared larvae, and the slope is not significantly different from 1(<i>p</i>>0.05). It is proved that ring on the otolith is formed daily. The first ring is formed mainly 3 (2-5) days after hatching which coincides with the first feeding.
