In the present study effects of injection of both 5-HT and DA on total moult duration of the intact and eyestalk ablated female prawn, Macrobrachium rosenbergii. The total moult duration was investigated through setogenesis of uropod. After injection of 5-HT prolongs the moult duration in intact prawns, however injection of DA caused to reduce moult duration period in intact prawns. Injections of both 5-HT and DA did not caused any changes in moult duration period in eyestalk ablated prawns. In the present investigation hypothesis that both 5-HT and DA involves in the regulation of moulting.
