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.
