Özet:

This study aims to detect the Ephemeroptera fauna of the Western Black Sea Basin, one of Turkey's 25 river basins, and to examine the ecology of the species. 24 stations, including streams and lakes, have been designated in the Western Black Sea Basin. Samplings of macrobenthic invertebrates were performed seasonal at 24 stations between May 2014 and October 2015 in addition environmental variables were measured in the same localities. As a result of Ephemeroptera sampling collected from the designated stations, a total of 2460 individuals belonging to 9 families, 19 genera, and 39 species were identified. In addition, the species detected in the study area were applied to the saprobic system and the current status of the stations was tried to be demonstrated in terms of water quality.
