Occurrence and seasonal changes of silica-scaled chrysophytes in Kachang dam reservoir were investigated with using electron microscopy (EM) and a light microscope. Total ten species were identified by an EM. Diversity of species was high in late spring and autumn and was very low during the summer and winter. Mallomonas caudata was found throughout the year and was present as an abundant population during the short period summer, whereas the other species were appeared as only a few cells or scales during other sampling periods.
