Total of 75 zooplankton species; 58 Rotifera, 12 Cladocera, 5 Copepoda species were identified in this pond. The datas of this study were evaluated number of individuals, frequency of occurence, species richness. As a result of Average Shannon Wiener index analysis of Maryap Pond, species richness was found highest in april (H’=1,96) and the least index value was found in september (H’=0,94). According to Margalef index analysis of Maryap Pond, species richness was found highest in april (D=4,01) and the least value was found in January (D=1,07). Among all zooplankton was represented with Rotifera 77%, Cladocera 16% and Copepoda 7%. Photos of some of zooplankton species were taken with Scanning electron microscope (SEM) and a computerized microscope system Clemex Image Analyser.
