The phyllosoma of Panulirus stimpsoni begin to feed about 1 -2 hours after hatching , and suitable diet of phyllosoma is Artimia salina nauplii. During phyllosoma stage Ⅱ、Ⅲand Ⅳ they eat A . salina nauplii. Its metamorphosis rate could reach 80 % ,40 % and 32. 5 % respectively. Phyllosoma have choice on different diets , and they can feed all day , and they have no rhythm of feeding. Light and darkness have no effect on their feeding and survival. In suitable density of A . salina nauplii , phyllosoma ( Ⅰ) can be full in 5 -9minutes and digest in 45 -90 minutes. The feeding of phyllosoma on different sizes of A . salina nauplii (349. 5 -604. 9μm) makes no obvious difference. This study can accumulate materials for the artificial culture of Panulirus stimpsoni phyllosoma.
