Scalloped spiny lobster (Panulirus homarus) is an export commodity and high economic value in Asian-Pasific markets, but the wild population was already over fishing. The purpose of this study was to determine the best combination of feed for nursery and grow out.

The nursery were conducted using 12 net cage 0,5x0,5x0,5 m put in the concrete tank 4x4x4 m in size with four treatment and 3 replicates. Four different foods were used as treatments, i.e.: combination of fish and green mussel (1:1) (A), fish and krill (1:1) (B), fish, green mussel and krill (2:1:1)(C) and artificial diet/pellet (D).The stocking density of post larvae was reared at 100 ind./m2. A complete random design was used as an experiment design. Data was analysed using ANOVA and descriptive statistics. Feeding times were twice a day at 08.00 and 15.00 at local time; wit dose 5% of biomass. The sampling of fry on nursery were conducted every 15 day to measure of survival rate(SR), total length (TL) and body weight (BW). On the end of the experiment also  take a sample of blood for haemocyte counting.

The result show that there was not significant different (P>0.05) among treatments for growth of total length and body weight. The best survival rate was on treatment D with survival rate (69.0%), followed by treatment B (17.5%: treatment C (15.8) and treatment A (11.7%). The number of haemocyte on the nursery was almost the same between treatments with haemocyte number about 200-250 x 103 per ml. From these results it can be concluded that artificial feed/pellet can be used for rearing of scallop spiny lobster post larvae.
