Different diets, feeding concentrations, starvation conditions, and temperatures were applied to the zoea of dancing shrimp (Rhynchocinetes durbanensis), and obtained the following results. The survival rate was the highest for the 5th-stage zoea when fed a combination of Artemia nauplii at 2/ml and rotifers at 15/ml. The survival rate of zoea was significantly related to the time of feeding after hatching. The survival rate decreased for zoea that was not fed on the first day after hatching. All zoea died within 2 days without feeding. The survival rate was the highest for 5th-stage zoea which had been raised at 24~27 °C. The period for development to 5th-stage zoea was the shortest for larvae which had been raised at 27~30 °C. The optimum rearing conditions were the combined feeding of Artemia nauplii at 2/ml together with rotifers at 15/ml, fed on the first day after hatching at 27 °C.
