To develop aquaculture techniques of Hymenocera picta, the effects of different types of diets, feeding concentrations, starvation, temperatures and salinities on the growth and survival were investigated. The result showed that 10 dph (days posthatch) larvae feeding with the nauplii of Artemia spp. at 2 and 4/ml of feeding had better survival rate and growth. About the delay of feeding, better survival rate and growth would be obtained under feeding within 2 dph. The survival rate was better in which salinity was at 24, 29, 34 and 39 psu. In addition, a better survival rate was obtained in which were raised during the water temperature of 24 ~ 30 ℃, but better growth was obtained at 30 ℃. Overall, the shrimp would have better survival rate and growth under conditions of 30 ℃, 24 ~ 34 psu, and feeding with the nauplii of Artemia spp. at 2 ~ 4/ml within 2 dph.
