    Zooplankton from Thi Vai River in Southern Vietnam

  • Original language description

    In this study, the variables of zooplankton and water quality were investiagted in Thi Vai River, Southern Vietnam. Zooplankton were monitored in April and September 2015 at 5 sampling sites in the river. Some basic environmental parameters were also tested including pH, total suspended solid (TSS), dissolved oxygen (DO), biological oxygen demand (BOD5), inorganic nitrogen (NH4+), dissolved phosphorus (PO43), and coliform. The biodiversity index of zooplankton were applied for water quality evaluation. The results showed that pH ranged from 6.8 - 7.5 during the monitoring. The TSS concentrations were in between 47 - 70 mg/L. The DO and BOD5 concentrations ranked from 1.8 - 6.1 mg/L and 4.2 - 17.7 mg/L, respectively. The NH4+ and PO43- were from 0.87 - 1.94 and 0.22 - 0.53 mg/L, respectively. The coliform number ranked between 2.3x103 - 1.1x104 MPN/100 mL. The zooplankton analyses showed that there were 43 species of cladocerans, copepods, coelenterates, mysidacea, prochordates, protozoans, and 5 larval types. Of which, species of copepods were dominant in species number. Zooplankton density ranged from 16,900 - 81,800 individuals/m3 with the main dominant species of Acartia clausi (Copepoda) and nauplius copepods. The values of biodiversity index during the monitoring were from 1.16 - 2.49 characterized for oligotrophic to mesotrophic conditions of the aquatic environment. Besides, species richness and density of zooplankton strongly correlated with DO, BOD5, NH4+ and PO43- while species richness and densities did not correlation with TSS and pH, respectively. The results confirmed the advantage of using zooplankton and their indices for water quality monitoring.
