To develop aquaculture activities mass seed production technology is essential. Hence in the present study an attempt was made to produce seeds in controlled condition. The complete larval development took a span of 22-26 days. According to Duncan’s multiple range test the larval duration is more or less same for I and III zoeal stages. Similarly II, IV, V and VI zoeal stages are also similar. However, I and III and II, IV, V and VI zoeal stages are significantly varied between each other. A maximum of 95% of survival was observed during the first zoeal stage and thereafter the survival was gradually decreased. The survival percentage shows that mortality was high in all zoeal and megalopa stages. The survival rate of zoeal and megalopal stages are significantly varied each other
