This thesis deals with the evaluation of concentration levels of phosphates, nitrates and other parameters (pH, conductivity, suspended solids, alkalinity, total carbon, inorganic carbon, total organic carbon and total nitrogen) in fishpond systems at Tabor. Further was to consider the difference in value depending on the age of the systems and agricultural activities in their vicinity. Samples were taken in season 2015 Liderovické pond system (2 sampling points at the top of the system, one sampling point in the outflow from the system), Radimovická pond system (one sampling point at the top of the systém, one sampling point at the outlet of the system) and Jordan ( one sampling point at the outfall of the pond). The highest differences were found in the values of conductivity from 279 S.cm-1 to 1230 S.cm-1, the values of total carbon from 18.75 mg.l-1 to 67.33 mg.l-1, and the values of suspended solids from 1 mg.l-1 to 117.33 mg.l-1. The gradual increase in the value of NO3-N and PO4-P was registered during the season with Jordan. Based on the results we can say that the older (Radimovická system) showed higher levels of total carbon and younger (Liderovická system) showed higher NO3-N depending on land use in the surrounding area.
