Description	Research was carried out to determine aquatic oligochaete habitat preferences in the Rokytna River (Thaya River basin), in the Czech Republic, April 1999-April 2001. Quantitative samples were collected and current velocity and basic physico-chemical variables were measured monthly in four typical habitats in the Rokytna River. During this study, 28, 842 individuals representing 44 oligochaete species or higher taxa were collected. Temporal variability of proportional occurrence of trophic groups found on selected habitats (gathering collectors and grazers) was analysed. Habitat preferences of oligochaete species were evaluated by CANOCO. BOD and nitrate ion concentration were the most important variables explaining the distribution of Oligochaeta along the first axis. Current velocity and presence of oligochaetes associated with the habitat where gravel bars never formed were the most important variables along the second axis. Both axes were correlated with the temperature.
