Rucki, Marek ; Bijok, Petr (referee) ; Radimský, Michal (advisor)
The thesis focuses on the development of a study for the municipality of Pohořelice. The town is located in the South Moravian region, Brno-Venkov district. It is located near the D52 highway. The thesis deals with roads I/53, II/395 and II/416 towards the south of the town. Several options for the area were considered and the most suitable option was developed in accordance with the municipality's master plan. The reason for the study´s preparation is to examine the area for the future development and to find a suitable solution for increasing vehicle intensity and safety improvment in the town.

Význam a úloha umělých vodních toků v soudobém městě
Vernerová, Nora
The thesis examines the role of the artifitial watercourses in urban landscape. The author divides the thesis into two parts, theoretical and practical. Theoretical part focuses on definitions, introduction and the relationship between the human society and the watercourse through ages. This part continues in the references and examples of the contemporary urban riverbanks both worldwide and in the Czech Republic. The second part presents the author´s own conception of the city watercourse revitalisation, namely the Millrace and part of Jihlava´s river in the city of Pohořelice. Applying the conclusions of the first part of this paper to the analysis of the model area, the author developes a study revitalizing the above mentioned local urban watercourses.

Male Sterlet (Acepenser ruthenus) Fertility under Fish Farming Conditions of the Czech Republic
SCHACHERLOVÁ, Jiřina
Currently, fish fertility studies are mainly focused on female fertility. Studies showing fertility of male fish of any kind are missing to a large extent. The main objective of my thesis was to identify what level of fertility is achieved by male sterlet (Acipenser ruthenus) in the conditions of fish farming in the Czech Republic. Male fish from the Vodňany farm where the raised population comes from Russia was compared to male fish from Pohořelice where the raised population comes from Danube. The total comparison test involved 49 pieces of fish. Following stripping to collect semen from male fish, the concentration of sperm (.109.ml-1) was measured in a 1 ml-1 semen sample. Consequently, a sperm count per 1 kg-1 male fish (.109.ml-1) and a sperm volume per 1 kg-1 male fish (ml-1) and a total male fish sperm count (.109) were measured. The highest values of weight identified in male fish was measured in the Pohořelice fish farm. The lowest values of weight was measured in male sterlet of the Vodňany fish farm. The highest as well as lowest volumes of collected semen per 1 kg-1 male fish were identified in Vodňany. However, the average volumes of both cultures were not significantly different. It was concluded by comparison that collected semena volume does not depend on the weight of said fish. Also, the relative fertility was significantly different between male fish of the same population. The highest and lowest sperm count per 1 kg-1 male sterlet were identified in Vodňany. The average minimum and maximum sperm counts per 1 kg-1 male fish were different very much which shows that a greater number of male fish should be used for spawn to ensure sufficient egg fertilization. The average overall fertility values in both cultures are very similar and mainly different in specific specimen of the same culture as well as between those cultures. The results showed that a total sperm count in semen depends on the volume of collected semen. It was further concluded that sterlet fertility does not depend on the size (weight) of fish.
