The study was implemented to analyze water quality and phytoplankton in rice – giant freshwater prawn (Macrobrachium rosenbergii) model in My Xuyen district, Soc Trang province. The water quality and diversity of phytoplankton were assessed through four sampling periods from 11/2019 to 1/2020. Six water samples and phytoplankton were collected at six sampling sites including one at the water intake, two in the rice field and three in the ditches. The water quality parameters including temperature, pH, salinity (S, ‰), dissolved oxygen (DO, mg/L), biochemical oxygen demand (BOD, mg/L), chemical oxygen demand (COD, mg/L), amoni (N-NH4 + , mg/L), nitrite (N-NO2 - , mg/L), nitrate (N-NO3 - , mg/L), total nitrogen (TN, mg/L), orthophosphate (P-PO4 3- , mg/L), total phosphate (TP, mg/L) và sulfate (SO4 2- , mg/L) were analyzed. Phytoplankton was assessed through both qualitative and quantitative analysis. In addition, the diversity Shannon-Wiener index (H’), Pielou’s evenness index (J’), Canonical Correspondence Analysis (CCA) and Pearson’s correlation were also conducted to evaluate the relationship between water quality and diversity of phytoplankton in the system. The results revealed that the water quality in the rice-shrimp system was relatively suitable for shrimp and rice, but BOD, COD, N-NH4 + , P-PO4 3- could result in an adverse effect on shrimp due to the bloom of phytoplankton; therefore, the water in the system should be exchanged regularly to avoid excessive nutrient accumulation. Eighty-six species of phytoplankton belonging to five phyla of Bacillariophyta, Chlorophyta, Dinophyta, Cyanophyta and Euglenophyta were discovered in this study. The values of H’ and J’ ranging from 2.0 to 3.3 and 0.8-0.9, respectively indicated high diversity and evenness of phytoplankton phyla in the system. The H’ values classified water quality from medium to good. The results of CCA indicated that the distribution of phytoplankton in the system depended on factors such as temperature, salinity, N-NH4 + , NNO3 - , TN, P-PO4 3- and TP. Besides that, Pearson analysis showed that the abundance of the dominant species of phytoplankton was closely correlated with temperature, salinity, BOD, COD and NNH4 + . This relationship illustrated the ability to quickly monitor water quality in shrimp ponds by using phytoplankton.
