Abstract

Scalloped spiny lobster (Panulirus homarus) is an high economic value in Asian-Pacific. The purpose of this study was to determine the best feed for spiny lobsters grow out in concrete tank. The study using 12 concrete tank 2.5x2.5x1m in size. Four different feed were used as treatments, i.e.: fresh feed (A), commercial pellet for grouper (B), for shrimp (C), and dry pellet Gondol formula (D). The lobster with initial average of total length (TL) 13.1 cm and body weight (BW) 78g was reared at density 25 ind./tank. Feeding 2x/day with dose 10% of biomass for fresh feed and 2% for dry pellet per day. The samplings were conducted on survival rate (SR), TL, BW, total haemocyte count. The result during 5 month rearing show that the best SR (94.67%) was on treatment D, followed by B (84.25%), C (82.67%) and A (50.67%). The highest final BW on D (204.1g), followed by A (190.5g), B (168.6g) and C (144.1g). The total haemocyte count was 292x104cel/ml almost the same between treatments. The conclusion is dry pellet formula IMRAFE Gondol is more feasible than another feed treatment for rearing of scallop spiny lobster grow out in concrete tank.
