Analysis of fishing pressure at sport fisheries managed by Czech Angling Union under the united fishing system.
 ŠMÍD, Pavel
The goal of the thesis was to analyse the fishing pressure, number of visits and number of catches in sport fisheries managed by Czech Angling Union (CAU). The selected data, mainly concerning the sport fisheries managed by South Bohemian Board of CAU, were graphically presented. At the trophy fishery Vltava 24, daily data were evaluated and the behaviour of fishermen was compared during the first two years of the new management (2010 and 2011). The second part of the thesis is aimed at the analysis of the united system of fishing management within the whole CAU and suggests a new system of financial flow. CAU is composed by 7 regional boards; however, it is possible to buy united fishing permit valid in all the fisheries of CAU. The financial budget coming from these permits is redistributed only according to the weight of killed and recorded fish. This system is advantageous mainly for regional boards with a big amount of fishermen and high fishing pressure at their fisheries; it is less advantageous for regional boards managing large areas. Within the thesis, a new model for redistribution of the financial budget was created. Except for the weight of killed fish, it includes other expenses connected with the management (fishing guards, lease of fishing waters, etc.) and the number of fishing visits. The model was provided to CAU for future negotiation.

Analysis of the Lipno dam reservoir fisheries management
 TOMS, Jan
The aim of the present bachelor thesis was to evaluate a development of the Lipno dam reservoir (the Vltava River, South Bohemia, Czech Republic) fisheries management during period from its filling in year 1958 to 1997 and during period 2004-2009. Fisheries statistics of number of stocked/caught fish (provided by the Czech Fishing Union; CFU) were used for the assessment of the state, as well as quantitative and qualitative changes of ichthyocenoses in time during monitored periods. These data were also compared with the results of the ichthyological screening at this dam reservoir in 2008 (undertaken by the employees of Biology Centre of the AS CR, v.v.i., Institute of Hydrobiology) in order to reveal a possible diference between a real fish assemblage compostion and structure of fishes caught by sport fishermen. Analyses of the catch sheets of the members of six choosen local organizations (belonging to CFU) from 2009 were used for evaluation of degree of fishing pressure during one choosen season (whole year) and for assessing of age structure of sport fishermen visiting Lipno dam reservoir.
