Özet

The present study, in which the diel vertical migration (DVM) of several zooplankton groups found in the Kadikoy Reservoir, was carried out during a 24-h period from7-8 May 2012. Vertical zooplankton samples were taken every 3-h eight times during a 24-h period, at 5-m intervals from the surface to the bottom, at the approximately the centre of the reservoir. An examination of zooplankton samples from the reservoir revealed a total of 36 taxa belonging to the Rotifera, Copepoda and Cladocera. An average of 371170 ind./m(3) Rotifera (67%), 122340 ind./m(3) Cladocera (22%) and 63928 ind./m(3) Copepoda (11%) was found an average of 557437 ind./m(3). The Cladocera and Copepoda populations were found mostly at 10th m and 15th in depths during daylight hours (13:00, 10:00, 16:00 and 19:00) and in surface layers during hours of darkness (01:00, 22:00 and 04:00). Generally, significant diel variation was not found in the Rotifera population. Abiotic factors, chlorophyll-a, time of day and depth significantly impacted the abundance of zooplankton; moreover, abiotic factors and chlorophyll-a were controlling factors on the vertical distribution pattern of the zooplankton in the reservoir. In addition, the main physicochemical conditions of the study area were found suitable for the life cycle of identified zoplankton populations.
