Effect of different diets on growth performance, physiological response and behavior of spiny lobster Panulirus homarus (Linnaeus, 1758)

This study aimed to know the effect of different feedings on growth performance, physiological responses, and behavioral changes juvenile spiny lobsters. The experimental method used a completely randomized design with three treatments four replications. There were feeds as treatment, namely: flesh mussel (K), commercial fish feed (I), shrimp (U). Feed is given much 30% body weight, five times per day at 6:30 am, 12:00 pm, 4:00 9:00 2:00 am. results showed that feeding (I) significantly (P<0.05) increased survival rate biomass lobster for 54.17% 141.7 g, respectively. While fresh give better stress response, but had lowest rate. response test more effective in suppressing levels than other (P<0.05). behavior lobsters very striking color difference reflex impairment scores, which indicated vitality treated juveniles was (K) treatment shows recommended maintaining phase, although it needs further maintenance by using an appropriate formulation improve performance
