Samplings were collected in two monthly intervals at four different stations during a year. Oligochaeta individuals were identified on species level and a total of 14 species (Tubifex tubifex (Muller 1774), Limnodrilus hoffmeisteri (Claparede 1862), L. udekemianus (Claparede 1862), Potamothrix hammoniensis (Michaelsen 1901) belonging to subfamily Tubificinae; Chaetogaster diaphanus (Gruithuisen 1828), Stylaria lacustris (Linnaeus 1767), Nais barbata (Muller 1773), N. bretscheri (Michaelsen 1899), N. elinguis (Piguet 1906), Ophidonais serpentina (Muller 1774), Pristina longiseta (Ehrenberg 1938), Slavina appendiculata (D'Ukem 1855), Dero digitata (Muller 1773), Aulophorus furcatus (Muller 1774) belonging to family Naididae and immature tubificidae with hair setae were determined. All the species identified in Sazlidere Stream are new records for the stream. In addition, C. diaphanus, N. barbata, N. bretscheri, O. serpentina, S. appendiculata, P. longiseta are new recods for Oligochaeta fauna of Turkish Thrace. According to Shannon-Weiner diversity index, it was found that Sazlidere Stream has H'= 0.72 diversity values at average. According to Bray-Curtis Cluster analyse results, 1st and 2nd stations have showed the highest similarity in terms of Oligochaeta species and their number and it is observed that this similarity is related to 4th and 3rd station, respectively. Also, water sampling was done to determine some physical-chemical features of surface water (DO, BOD, SO4-2, PO4-3, NO3--N, NO- (2)-N, Mg, Ca, Cl, Chlorophyll-a, suspended solid material, organic matter) and microbiological analysis (total bacteria, total coliform and E. coli). Furthermore, the relationships between oligochaeta species and physical-chemical features was analysed by one way ANOVA test.eninfo:eu-repo/semantics/closedAccessSazlidere StreamOligochaetaFaunaPhysicochemical ParametersArticle632179185Q4WOS:0002940864000072-s2.0-84887051359Q4
