Natural Swimming Pool for a Small Municipality
Mrkývka, Michal ; Hyánková, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
Bachelor thesis deal with natural swimming biotope. In the first part concetrates on the principle of water purification natural swimming pool, a device used for the operation, properties of water, right sort of plant and regulations dictated by the state. In the sekond part presents free selected natural swimming pool in southern Moravia, compares selected indicators in bathing water and source water in natural biotope. At first depots graphic progres sof temperature, transparency and pollution in a particular biotope and then compares individual biotope between them with respect to the notice of the Ministry of Health.

Verification of the Relationship between Stock Density and Transparency of Water
CHMELICKÝ, Petr
The given study reveals results which were obtained after having conducted a survey on the physical and chemical properties of water including its transparency, along with zooplankton sampling and the measurement of dynamics related to fish stock growth. This research was conducted in three different ponds with surface areas of 68.2 ha, 48 ha and 5.5 ha, situated in the Protected Landscape Area of Český ráj (Bohemian Paradise). These ponds were stocked with carp in the age group from K2 to Kv, at an initial weight of fish stock 196 kgxha-1, 102 kgxha-1 and 127 kgxha-1. The ponds in question were selected so that they either differ in size, or in the intensity of their fish farming. Plankton samples were collected by using the Schlott Fichtenbauer Bauer probe based on the principle of a Schindler-Patalas plankton trap.
