The aims of this study were to review the variation of environmental factors on the growth of black tiger shrimp (Penaeus monodon Fabricius, 1798) in ponds multi-cycle intensive multi-pond in Hai Phong. This study aimed at paving the way for the construction of a complete multi-level farming in intensive shrimp farming. The author implemented research on fluctuations of some environmental factors (temperature, pH, turbidity, oxygen, salinity, alkalinity, NH3, NO2, H2S, water level) on the growth indicators in ponds multi-cycle intensive multi-pond in Hai Phong. The experiment was arranged in 3 modules (module level, module level 2 and modules level 3). As a result of environmental factors in all 3 modules (temperature 26.7 - 34oC
