No results found.The paper is based on experiments and observations made at Penang, Malaysia. Macrobrachium rosenbergii is widely distributed in fresh and brackish waters in southeast Asia. It is omnivorous and its feeding behaviour is described. An account is given of moulting, mating and egg-laying and of embryonic, larval and postlarval development. The larva undergoes ll moults before reaching the juvenile stage, but only 8 larval stages are morphologically distinct. At 26 to 28°C, embryonic development take s 19 to 20 days and larval development takes 30 to 45 days; when cultured in ponds, the prawns become fully grown 7 to 8 months after metamorphosis. The larval stages require brackish water for survival. Under natural conditions, the juveniles migrate to fresh water and adult females release their larvae in the upper parts of estuaries.
