Seasonal succession and community composition of planktonic ciliates were studied in Kyungan Stream from December 2000 to December 2001. Oligotrichs accounted for 53% of total ciliates. Total abundance of ciliates peaked in spring (30 March, 6 April) and in summer (8 June, 20 July) reaching values up to $1.9 imes10^4$ cells $L^{-1}$. Seasonal succession of dominant species occurred obviously. Large-sized $(>50{mu}m)$ species (Stylonychia sp1, Phascolodon vorticella and Codonella cratera) dominanted from winter to spring. Small sized $(<30{mu}m)$ species (Vorticella spp., Rimostrombidium hyalinum and Halteria grandinella) dominanted in summer and autumn. Total abundance of large-sized species coincided with the Chl-${alpha}$ concencetation during the study (r=0.33, p<0.05, n=39). Among the small-sized species Halteria grandinella was a significant relationship with bacterial abundance (r=0.35, p<0.05, n=39).
