Present study was carried out to determine the littoral fauna of Oligochaeta of Lake Egirdir, an Important Bird Area (IBA) located at 918 m in the southwestern part of Turkey (38 degrees 00'N, 30 degrees 54'E). The samples were collected from 17 stations from May 2002 to October 2002. As a result of this study, 22 species, which belong to 15 genera, consisting of 1 species from the family Lumbriculidae, 1 species from the family Haplotaxidae, 9 species from the family Tubificidae and 11 species from the family Naididae, were determined at 17 stations. The littoral fauna of oligochaeta in the lake Egirdir was dominated by widely distributed tubificid and naidid taxa. The tubificids Tubifex tubifex (19.2%), Limnodrilus hoffmeisteri (17.9%), and Potamothrix hammoniensis (11.3%); and naidid Ophidonais serpentina (9.3) were the most abundantly found species in the study area. According to Shannon-Wiener index, Lake Egirdir was found had 1.45 richness and, 5th station were found to have the widest diversity (1.93) while 11th station to have the poorest (0.97). In the study area high Tubificidae population has been observed, and high pH, relatively low Oligochaeta diversity (1.45) showed that similar studies should be repeated periodically in Egirdir to determine the future of the Lake.
