The study was conducted between March 2017 and February 2018 to determine the effects various applications and environmental impacts on zooplankton composition in Sakaryabaşı-West Pond. Zooplankton samples were monthly collected with plankton net vertically and horizontally from two stations as triplicated. At the time of sampling, water temperature, dissolved oxygen, pH, electrical conductivity, water depth and light transparency were measured at the stations. Rotifera was the highest proportion in the pond during the study, followed by Copepoda and The study was conducted between March 2017 and February 2018 to determine the effects various applications and environmental impacts on zooplankton composition in Sakaryabaşı-West Pond. Zooplankton samples were monthly collected with plankton net vertically and horizontally from two stations as triplicated. At the time of sampling, water temperature, dissolved oxygen, pH, electrical conductivity, water depth and light transparency were measured at the stations. Rotifera was the highest proportion in the pond during the study, followed by Copepoda and Cladocera, respectively. At this research, 11 families from Rotifera, 22 species from Cladocera, 1 family from Cladocera, 1 family from Copepoda. Proportionally most common species were Lepadella patella (6.38%), Mytilina ventralis (5.32%), Lecane lunaris (4.79%) from Rotifera; Alona rectangula (8.51%) from Cladocera. Cyclopoidae copepods was formed as adults (17.55%), nauplii (25.53%). During the study period the average zooplankton abundance ranged from 3 ± 0.5 x10 3 to 36 ± 2 x10 3 / m 3. The highest abundance value was determined in October and the lowest abundance value was determined in January. As a result, regular monitoring of zooplankton in Sakaryabaşı-West Pond as an indicator of the ecological health of the water bodies, will be important in terms of being a warning for the negative impacts of the pond.
