✦ Synopsis

Individuals of the oriental brown shrimp Penaeus ]aponicus BATE, were raised separately (l shrimp per rearing cage) with surplus food, in almos~ dark, non-sediment conditions. Results were obtained regarding growth of each part of the body in conjunction with exuviation and molting cycle. Increases in carapace, body length and body weight conformed to the general pattern discribed by I-IIATT (t948), with no difference in growth resulting from sex, or inflexion point in juvenile stage. The molting cycle of shrimp weighing 1.5 to 15 g was 6 to 17 days at a water temperature of 20 ~ to 28 ~ The molting cycle was prolonged in proportion to the size of the shrimp; shortened as the water temperature increased.
