The small reservoirs as part of cultural landscape
Portová, Nikola ; Vrba, Ing Jan (referee) ; Milerski, Rudolf (advisor)
While the title of this thesis is “Small reservoirs as a part of the cultural landscape”, the focus of this study is much broader. The analysis goes beyond small water reservoirs, discussing both the historical and technical aspects of their restoration with emphasis on the south Moravian reservoir systems. The opening chapter explores the history of the relationship water has with both society and nature. In the second chapter, the focus shifts onto the various roles, the physical and technical characteristics, as well as the methods for restoring small water reservoirs. In the final chapter, the emphasis shifts from reservoirs to ponds - and their utilization for farming fish. This chapter starts by exploring the current pond systems across Czech Republic, and then compares today’s south Moravian pond systems to their historical beginnings.

Assessing the Possibility of Setting up a Dam
Prokešová, Eva ; Hlavinková, Vítězslava (referee) ; Hrubanová, Michaela (advisor)
The aim of the thesis is to assess the possibility of establishing a water reservoir in s selected location witch regard to its possible water management activities including geological conditions. The thesis also defines basic terms related to water reservoir and their parts. This work was elaborated with the help of available literature and valid laws of the Czech Republic concerning the given issue. At the end of the work will be valued land meeting the conditions for the construction of a small water tank. The award will take place in two ways according to the decree and direct comparison.

The Occurrence and Basic Aspects of the Biology of Pseudorasbora parva (Temminck et Schlegel, 1842) in a Model Pond System located in the region of Třeboňsko
ČECH, Miroslav
The stone moroco (Pseudorasbora parva) is a invasive little fish whose species origin is not from our waters. It is desirable to eradicate this species from the Czech environment or at least decrease its numbers as much as possible, using an environmental method. The data for the dissertation was found out on a model pond system in Třeboňsko. This complex consists of thirteen ponds 203.1-hectare. The ponds in this locality are highly productive and their average depth is about one meter. The aim of the dissertation was to determine the composition of feed of Pseudorasbora parva and according to this, to assess the potential importance of this species as a rival to the locally bred carp (Cyprinus carpio). The other submission was to map the migration of Pseudorasbora parva in the aforementioned pond system and to determine what part of the pond is the most coveted by this fish and estimate the total number of fish population in some ponds. The use of fingerling nets was one of the methods used to catch Pseudorasbora parva in the shallow water of the ponds. Furthermore fish-pots were used for catching fish in the deeper parts, and drop nets were used for catching in the effluents. The Pseudorasbora parva was present for a whole calendar year in all parts of the system i.e. in all ponds, drains and in their effluents. The stone moroco occurred predominantly at the banks of the pond. The occurrence of fish in the open water was recorded sporadically. The sampling of plankton was carried out with plankton net in different seasons. With exception of winter when plankton was not found, the composition of feed the same during the whole year. Only proportional representation of species of plankton was different. The catching of Pseudorasbora parva was performed in the ponds Pražský, Rod, Láska and Víra, the fish was necropsied for assessment the intestine content. At the same time four carps of age group K2 were necropsied. By the analysis of the intestine content the conformity in the feed consummation by both aforementioned fish species was confirmed.
