The historical development of landscape in South Bohemia
VAVRUŠKOVÁ, Zdeňka
This bachelor thesis describes the historical development of landscape at times of Lords of Hradec, Lords of Rožmberk, Schwarzenberg sand at times of Hussitism. The thesis also deals with the development of pond culture, the description of landscape after Thirty Years´ War, The Second World War and after the year 1989. There are depicted the changes of the landscape in each time period. The main attention is paid to the changes of forests, water management and agriculture. The most important changes of landscape are associated with the time of wars, when the landscape was devastated. The image of landscape is also influenced by human settlement, the forests are often cut down, the plough land is dissolved etc. because of the growing built-up area.
Comparison of growth and survival of selected tench breeds in performance test
PRCHAL, Martin
This thesis is focused on comparison of performance traits of growth and survival of selected breeds of the common tench using the pure-blooded animal breeding method. The best way how to compare performance traits of particular breeds is through so-called performance tests. For this thesis following breeds were chosen: Vodňanské -(V), Hlubocké(H), Königswartha (German - N), Mariansko-Lázeňské (ML) and Romanian(R). The Golden tench were chosen as a control breed in order to correct the influence of the environment on the weight achieved. The testing began with selection and stripping preparation of spawners of relevant breeds selected for testing. Own performance test of selected groups proceeded from yolk - sac fry to the age of L2 in ponds with semi-intensive farming. Each tested breed was bred in the first growing period and in winter period together with the control group only. After group marking (the second growing period) by the cryogenic method, all breeds were bred together with triplication. In the first testing period reproductive parameters of spawners and their weight and survival of tested breeds were evaluated, in other period only weight and survival were evaluated. Reproductive parameters in males did not vary statistically in none of the parameters using any statistical method. In females significant differences were proved only between the breeds ?Hluboká? and the control breed. After the second growing period the highest weight was achieved by the Mariánsko-Lázeňské breed (112.9 ? 44.9 g), whose weight was statistically comparable only with German breed (105.4 ? 32.4 g). The survival after this period ranged from 70,4 % (Romanian breed) to 84,1% (Mariánsko-Lázeňské breed) and all breeds had statistically comparable values. The best performance traits after the second year of testing was achieved by the Mariánsko-Lázeňské breed.
