Résumé
Samples were collected from 9 stations seasonally between June 2011-December 2013 for evaluation ecological quality of Sapanca Lake by using macroinvertebrate from biological parameters according to Water Framework Directive. In addition, some environmenteal variables (pH, temperature, dissolved oxygen,) were measured in situ and NO3⎯N, NH4-N and Biological Oxygen Demand were measured in laboratory. Consequently, Totally 79 taxa were identified in Sapanca Lake (13 of them belong to Gastropoda, 20 of them belong to Oligochaeta and 38 of them belong to Chironomidae). The zoobenthos samples from Lake Sapanca were contained the following invertebrate groups : Oligochaeta (39.24%), Gastropoda (22.72%), Bivalvia (10.68%) and Chironomidae larvae (8.86%). Potamothrix hammoniensis belong to Clitellata was the dominant zoobenthic species (29.06%) of the total benthic fauna followed by gastropod Borysthenia naticina (16.71%), clitellat Limnodrilus hoffmeisteri 6.19% and chironomid Einfeldia carbonaria (2.12%). Biotic indices (BMWP-Biological Monitoring Working Party Score and ASPTAvarage Score Per Taxon) and diversity indices were used (Dominancy, Shannon-Wiener, Simpson, Evenness and Margalef). According to results of BMWP, 2. and 4. station were determined as heavily polluted while the other stations were determined IV. quality (polluted or impacted). ASPT values were determined polluted at all stations. The values of Shannon- Wiener Diversity Index were varied between 0.27 and 1.25. Sapanca Lake is determined as mesotrophic according to both biotic indices and environmental parameters. Potamothrix hammoniensis, Lithoglyphus naticoides and Fagotia esperi, to which the population in Lake Sapanca can be attributed emphasizes the Danubian relationship of the Lake Sapanca invertebrates fauna.
