The aim of the thesis was the appraisal of Great Crested Grebe (Podiceps cristatus) nesting biology aspects in relation to environmental conditions. The research took 6 months from the 2nd of April to the 2nd of October in 2013 and was realised in the Naděje fishpond system on the ponds Víra, Láska, Skutek, Dobrá Vůle, Rod and Naděje. This fishpond system is situated in CHKO Třeboňsko nearby villages Frahelž and Klec and it consists of total of 15 ponds which are used for intensive fish farming, partly for breeding of Wild Ducks for hunting purposes. The counting of birds, active searching of nests and measuring parameters of nests and eggs were carried out during the work. The nests were found on ponds Naděje, Skutek and Láska. In 2013 18 nests were measured altogether. On the fishpond Naděje 8 nests were situated, on the fishpond Láska 4 nests and on the fishpond Skutek 6 nests altogether. 13 nests of the total were found on a free water surface and 5 nests were situated in the vegetations of the Great Reedmace (Typha latifolia) at a maximum distance of 1 m from the free water surface. In 2013 64 eggs were measured altogether. On the fishpond Naděje parameters of 33 eggs were obtained, on the fishpond Láska 17 eggs and on the fishpond Skutek 14 eggs were found altogether.
