Özet

Annelids were collected seasonally at Riva Stream from March 2018 to January 2019. In this study, 1241 individuals (28 taxa; 4 families) of Annelida were identified. Various physicochemical pa-rameter values [depth, width, flow rate, water temperature, dissolved oxygen, pH, electrical con-ductivity, salinity, TP, o-PO4, NH4-N, NO2-N, NO3-N, TSS] were measured seasonally. The re-sults of the analyses were evaluated according to TSWQR (2021). NPI water index values of the stations were also calculated in the study. Accordingly, it was found that the water quality of Riva and Değirmendere was more polluted than other stations. Bray Curtis similarity analysis was also evaluated regarding physicochemical parameters and taxa. Stations 2 and 3 were the most similar in terms of physicochemical parameters. In terms of taxa, stations 3 and 4 were found to be the most similar stations. According to CCA analysis, U. uncinata and L. hoffmeisteri appeared closely related to salinity, while E. tetraedra, H. naidina, H. stagnalis, P. deserticola and Nais sp. were shown closely related to width.
