dc.description.abstractCurrently, Aquamimicry concept was introduced and practiced in shrimp farms in aiming of providing natural estuarine condition for the culture species. The success of this method includes reducing feed conversion ratio, minimizing water exchange and improving post larvae quality. In light of this, an attempt was undertaken to investigate the effect of Aquamimicry on the seed production of black tiger prawn (Penaeus monodon), compared with a control tank (without natural estuarine condition). The result showed that several issues significantly improved with the administering Aquamimicry system in the experimental tanks compared with the tanks without Aquamimicry system. Data were analyzed using MANOVA (P < 0.05) in SPSS software to determine significant differences of growth parameters. The size variation was observed lower in the control tanks than in the experimental tanks. Moreover, the muscle gut ratio of PLis was about 80±1.677% in the Aquamimicry tanks and 78.5±2.905% in the control tanks during the two cycles of production. The fouling organisms were more in the control tanks compared to the experimental tanks. The average lengths of PLio and PLis were maximum when reared in the experimental tanks compared to the control tanks. Which shows significant difference and the \Tattles are 10.56+0.043mm in experimental tanks and 10.38+0.043mm in the control tanks. Several test were perform to test the Post larvae quality but those test did not show any significant difference. During stress test the experimental tanks showing more survival than the control tanks. And also the test for the necrosis and abnormalities and swollen. hind gut also shows a decreased percentages than a control tanks with a difference of 1.5%, and 0.17% respectively. The final survival rate of PLis from the control and experimental tanks was 44.9±0.825% and 50.22±0.477% respectively. The present investigation indicated that Aquamimicry concept played an important role in the health, growth and survival of Penaeus monodon larvae.en_US
