Analysis of ichtyofauna of the Czech Republic focused on alien species
Goldstein, David ; Hanel, Lubomír (advisor) ; Andreska, Jan (referee)
This thesis analyzes the ichthyofauna in Czech Republic in historical terms, i.e. how was the data on the occurrence of native species of fishes and lampreys collected. Particular attention is given to species alien to this territory - the following species are elaborated in more detail: Carassius auratus, Ameiurus nebulosus, Pseudorasbora parva, Ctenopharyngodon idella, Hypophthalmichthys molitrix, Aristichthys nobilis, Gasterosteus aculeatus, Coregonus maraena,Coregonus peled, Acipeneser baerii, Acipeneser stellatus, Acipenser gueldenstaedtii. The history of the introductions, the current situation in the Czech Republic and the impact on native ichthyofauna are listed (a more detailed evaluation of invasiveness is included for Carassius auratus, Pseudorasbora parva). Finally, the efforts to enrich the local ichthyofauna by introducing new species are generally evaluated.

Complex ichtyological investigation of the Lipno Reservoir in 2017
Soukalová, Kateřina ; Kubečka, Jan ; Bartoň, Daniel ; Děd, Vilém ; de Moraes, Karlos Ribeiro ; Jůza, Tomáš ; Souza, Allan T.
The aim of the study was to monitor the overall status of the fish stock of the Lipno reservoir in the key year 2017, when the fishing rules were changed. The catches of multimesh gillnets, fry trawling, seining and electrofishing, and the assessment of European catfish were evaluated. The species composition and relative abundance of fish in all significant reservoir volumes were found, and the year class strength of all species 2017 was quantified. The report also contains recommendations for further fishery management of the reservoir.

Sport Angling in Prague and Main Motivation for this Hobby
Dopitová, Aneta ; Hanel, Lubomír (advisor) ; Andreska, Jan (referee)
My thesis is called "Sport fishery in Prague and the main motivation for this hobby". The Vltava river belongs to the main rivers in Czech Republic. It begins its flow when the Warm Vltava and the Cold Vltava join is the Šumava mountains. In my thesis I occupied with the analysis the Prague's part of the Vltava river. I concentrated to the quality of the water and local ichtyofauna. There is mentioned the history of the fishery in Prague and current situation of the fish territory. In detail there is watched the fisgery at the territories Botič 2 (ÚN Hostivař) and Vltava 5. Here I watched the catches of the specific fish's species in the fixed period. Using the survey I found out the motivation for the fishery and student's knowledge of the "Fishes" at the chosen secondary schools. At the end I prepared themes (theoretic and practical) as a content of the kid's fishery society for the whole school year. Key words: The Vltava river, fishery, fish catches, motivation, students

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.
