Further more work is targeted on evaluation of anual catches of fish listed below on trout areas Svitava 3,4 and 5 in last 15 years. This results will be compared to fishing pressure on monitored areas with level of releasing of fis listed below. For evaluation of catches, fishing pressure and level of released fish was used evidence of trout kinds fish areas MRS in Brno. Results are showing, that the largem number of catches in last 15 years are in Svitava 3 area, which i also under the biggest fishing pressure. On the contrary the most fish released were in area Svitava 5. Enviromental factors in Svitava river are distictly better than in 1989.

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.
