 Kučera, Štefan
The diploma thesis is primarily focused on the standardization of Daphnia magna breeding in laboratory conditions of the Department of Zoology, Fisheries, Hydrobiology and Beekeeping at the Faculty of Agronomy of the Mendel University in Brno. The main aim of the work is to simplify the preparation of medium for breeding Daphnia magna due to time saving. During testing, we were interested in births and mortality of individuals observed during 14-day tests in two media. We focus on chemical and physical properties of the media, namely the pH, temperature and intensity of the light.
