Since the year 2013 there is going a hydrobiology monitoring of some selected ponds in Duchcov. It is Rybochovný n. 1, Rybochovný n. 2, Rybochovný n. 3, Kravský, Růžový, Dubský and Barbora onces, when all ponds were for some time monitored in basic hydrochemical parameters: temperature, alkalinity, conductivity, oxidation reduction potential, dissolved oxygen concentration in water, transparency and turbidity. I examined seasonal change in phytoplankton and zooplankton composition. I compared my results with data from previous years. In these ponds is a risk of eutrophication, resulting in the occurrence of algal blooms. Several situations with the occurrence of algal bloom was observed during monitoring. This would may be problem for ecological conditions of pond´s reservoirs, also for fish composition because of oxygen out-pumping. There weren´t noticed extreme changes during pH monitoring, even so it is important to monitor the supply of nutrients and in case of deflection to make various steps.
