Conditional indicator in breeding market carp in semi-operation experiments in fish-ponds in Třeboň
FLOKOVIČ, Ondřej
In my bachelor thesis, I dealt with supplementary feeding of common carp (Cyprinus carpio, L.) in semi-operation experiments in fish-ponds in Třeboň. For the experiment, three-year carp of the operation line scaly Třeboň carp was used. The main objective of the experiment realized by me was to compare the feed triticale in various modified forms. For extra feeding, the feed triticale was used in three modified forms (whole triticale, pressed triticale, whole triticale thermally processed at 100°C). The feeding study was realized for the assessment of conditional indicators of market carp. For the experiment, which lasted 83 days, four fish-ponds were used. 363 pieces were set per hectare of fish-pond. In the fish-pond No. 1, whole triticale was used for supplementary feeding. In the fish-pond No. 2 pressed triticale was used for supplementary feeding. In the fish-pond No. 3, whole triticale thermally processed at 100°C was used for supplementary feeding. The fish-pond No. 4 was used for control without supplementary feeding. During the experiment, control fishing was performed to measure body length, body circumference, body weight and measure fat in the fish muscle. There was a considerable difference in the final weight between the feed whole triticale thermally processed at 100°C in comparison with the control group without supplementary feeding. It was the biggest gain from all tested feed types and reached 12.061 kg. The results of all tested feed types were best for the feed whole triticale thermally processed at 100°C, which proved to be the most suitable.

Evaluation of carp fish-scale reading production indicators in fishponds
PETR, Miloš
The main fish in the Czech pond aquacultures is Cyprinus carpio (common carp). All forms of carp feed on natural food and additionally they are fed with bread cereals. In the literary review I will describe the various cereals, which are used in carp-scale reading. Further I'll try to focus on the editing posibilities of the various cereals to increase their productive effectivity. In the chapter "Results and discussion" I will describe the characteristics of growth and condition indicators of experimental fish stocks during the growing season, in experimental ponds in South Bohemia, near the city of Třeboň. Finally, I review the results and try to propose some ways to use different feeds in working practices.

Feeding of wild boar in hunts of Chlum and Sepekov
KOTALÍK, Tomáš
The bachelor thesis is focused on feeding of wild boar in two hunts. The first hunt which was chosen is the hunt of Chlum. The second hunt which was chosen for monitoring is the hunt of Sepekov. There were chosen two feeding places for monitoring in each hunt. The monitoring started in March 2009 and ended in February 2010. The monitoring of feeding should display differences between forest and mixed hunt. But the main reason was to find out the intensity of visits of wild boar in particular seasons pursuant to the influence of different factors. These factors were judged: climatic (snowfall, rainfall and temperature), the influences of sowing and harvest of agricultural crops during the year, the influence of collective hunting on wild boar near the feeding place and shooting on feeding places. The influence of feeding on the damages made by wild boar to fields was judged too. Localities were controlled twice a week. The feeding places were controlled by Ir-C cameras which were given on two feeding places once a week. These facts were found out by the observing. The intensity of visits on the feeding places is very different in particular seasons. The visit rate of feeding places isn´t influenced by the production of forest seeds in spring. We found out that the most favourite feed in this season was maize. Wild boar stays in agricultural monocultures in spring and on feeding places comes minimally. The popularity of particular sorts of feed depends on the term of their putting and hunting of wild boar in autumn and winter. We can avoid the damages to agricultural crops in spring, autumn and winter if we will have large enough forest in which we will be able to hold wild boar by feeding. The visit rate of the feeding place is influenced by the hunting near the feeding place, but the intensity of this influence depends on the scope of the hunting and the number of hunted members of herd which visited this feeding place. Wild boar visits the feeding place about two or three hours earlier in time of indigence. But during the rain it never appears on the feeding place.
