To detect the distribution of Oligochaeta fauna of Yuvarlak Stream in the Köyceğiz-Dalyan Protected Area in South-Western Turkey, monthly samplings were made from 11 stations from May 2001 to April 2002. The samples were collected by using 180 µ and 500 µ mesh sized hand nets and an Ekman-Birge Grab in 9th and 10th stations.
