Abstract: Juvenile scalloped spiny lobster Panulirushomarus with body weight of (18.15±1.85)g were divided into three groups including control group(intact lobster), eyestalk-ablation group and antenna-ablation group and reared conventionally in a 0.5 m3 plastic circular bucket with three replicates of each 15 individuals for 120 days to investigate the effects of eyestalk and antenna ablation on the survival, molt, feeding and growth of the lobster. The results showed that there was significantly higher survival rate in the lobster in eyestalk-ablation group than that in the antenna-ablation group and control group (P<0.05), without significant difference in survival rate in the lobster between the antenna-ablation group and control group (P>0.05). The first molt was significant later observed in the lobster in the antenna-ablation group (P<0.05), though there was no significant effect of eyestalk-ablation on the molt cycle (P>0.05). The antenna was found to be regenerated in the lobster with the twice antenna-ablation which there was no significant influence on the molt cycle after the two molts (P>0.05), with significantly longer molt cycle in the antenna-ablation group than that in eyestalk-ablation group and the control group throughout the experiment. The lobster with eyestalk-ablation had significantly higher food intake rate and lower food conversion ratio(P<0.05). The significantly higher food intake rate and food conversion ratio were found in the lobster in eyestalk-ablation group than in the control group (P<0.05). The eyestalk-ablation led to significantly promote the growth of the lobster due to higher weight gain rate, length gain rate and specific growth rate at different time compared to the other two groups (P<0.05), without significant effect of antenna-ablation on the above growth indicators (P>0.05). It is concluded that the eyestalk ablation results in improvement of survival rate, feeding and growth of the lobster, which is worthing application and popularization in aquaculture production. However, the antenna ablation not only serves no benefit to the growth of the lobster, but also leads to the death as a result of pathogen invasion, with careful harvesting of the lobster in aquaculture production to keep the integrity of antennae.
