The object of my thesis was to document the basic characteristics of four small ponds. Register seasonal changes in the occurrence of selected zooplankton groups and compare individual ponds among them. Then evaluate management on ponds and assess the possible impact on the formation of plankton. These results were then compared with the current situation on standard economic ponds. In this study, I observed three private ponds and local pond, which were located in the cadastral area Lodhéřov. From the results it is evident, that the zooplankton development was in private ponds very slow, while at local pond was developed zooplankton quickly. The diversity of zooplankton species was higher in local pond. On private ponds showed a high increase in fish, which amounted to R1 597 kg/ha and R3 519 kg/ha. In terms of management of ponds R2 was the least effective because the gain was only 113 kg/ha. Private ponds, according to the average annual ration 2910 kg/ha still ranked in halfintesification, while local pond to intensification ration with 4557 kg/ha.
