• Larval growth and elemental composition of kuruma prawn Penaeus japonicus reared from the nauplius stage to the 15-16th day of the postlarval stage (24 days) were determined by conducting ten experimental rearing runs. The larvae from the nauplius stage grew linearly against a logarithmic fresh body weight to the 1st postlarval stage (27±1°C), while the growth increments of the postlarvae reared at 23±1°C decreased proportionally. The water component of the larvae over all stages constituted ca 79% of fresh body weight. The content of three elements (C, N, P) was ca. 38, 9.6, and 1.5% in dry body weight, respectively. C: N ratios decreased as the dry body weight increased. This tendency implies that the larger larvae accumulated more protein than lipid in their body. The average C: N: P atomic ratio over the larval stages was 24:6:1.
