Abstract

Phytoplankton and zooplankton community structures in the Bangpakong River were investigated in April, July, September and November 2016. Samples were collected from six stations using plankton nets with mesh sizes of 20 and 200 micrometers for phytoplankton and zooplankton samplings, respectively. In total, 3 divisions, 6 classes, 61 genera were recorded namely Division Cyanophyta (11 genera) - Class Cyanophyceae (11 genera); Division Chlorophyta (19 genera) - Class Chlorophyceae (15 genera) and Class Euglenophyceae (4 genera); Division Chromophyta (31 genera) - Class Bacillariophyceae (25 genera), Class Dinophyceae (5 genera) and Class Dictyochophyceae (1 genus). Diatom was the dominant group in all four studied months. The study on zooplankton community revealed 25 groups belonging to 9 phyla. Of which, Copepoda was the dominant group in all four studied months. The environmental factors including salinity, dissolved oxygen, pH and temperature affected the changes of plankton community structures in the Bangpakong River.Keywords : plankton, water qualities, Bangpakong River
