Abstract

Zooplanktons are important elements of an aquatic ecosystem such as ponds. They are involved in rotation of materials, control of algae communities and microbial production. The aim of this study was to investigate the frequency and identification of Zooplankton in sturgeon fish ponds of Shahid Beheshti aquatic reproduction and reconstruction complex and their relation with physical and chemical factors of water. Five ponds were studied. Physical factors such as dissolved oxygen, temperature, pH and saturation, and chemical factors such as nitrite, nitrate, ammonia and orthophosphate were measured twice a week with 3 replicates. A total of 22 genera were identified from 4 branches of Cladocera (5 genera), Copepoda (3 genera), Protozoa (2 genera) and Rotifera (12 genera) in the studied ponds. The highest variety and abundance were found in Rotifera and Copepoda respectively. Nauplius, Daphnia and Cyclops had the highest percentage of Zooplankton with 46%, 25% and 15% respectively. The results of measurement of physical and chemical factors of water indicated optimal water conditions of the ponds and only the orthophosphate factor was higher than the limit. There was a significant negative correlation between pH and orthophosphate factors (P> 0. 05). There was a significant positive correlation between Cladocera and orthophosphate factor as well as Zooplankton and nitrate factor in all ponds (P<0. 01). Based on the results, the ponds were in optimum condition in terms of physical and chemical factors and Zooplankton population and only the orthophosphate factor was above the permissible limit which could be controlled by proper management.
