Morphometrical and Morphological  characteristics of the prawns were analyzed descriptively and the prawns sampled were identified. The results found that there were two types of shrimp included in the Penaedae family of the genus Penaeus that live in the habitat of the mangrove ecosystem, namely (1) Panaeus monodon and (2) Panaeus merguensis.  Detail identification showed that they were Panaeus monodon(37 specimens, 17 males and 20 females)  andPanaeus merguensis(42 specimens, 20 males and 22 females).The waters parameters measure in mangrove ecosystem that is dissolved oxygen 7,3-8,1 mg/L, temperature 28-30oC, clarity148-190,5 cm, salinity 25-30 mg/L, pH 6,5-7,5, O₂7,3-8,1 mg/ l, alkalinity 52-100 mg/l.
