Current possibilities of breeding and production of whitefish in the Czech Republic
MRÁZ, Luděk
The main goals of this thesis are description of a quite complicated peled breeding topic in the Czech Republic, evaluation of inconsistent taxonomical data, biology and ecology of the Coregonus maraena and Coregonus peled. The approach to peled breeding is in detail evaluated recently as well as in the past. Methods of breeding, fishing out, fish tank breeding and fish transfer are addressed. The questionary survey among peled producers was used for critical evaluation of their experience. The factors that discourage producers from peled breeding (eutrophication, predation by cormorants or otter as well as technological difficulties) were stated. Due to these factors the peled production is limited despite the stabile market demand. The case study of peled production was realized. In the condition of huge fish stock (carp and grass carp) the main negative impacts were confirmed.

Breeding burbot (Lota lota L.)in the Czech Republic
MRÁZ, Luděk
Zabývám se chovem mníka jednovousého různými metodami chovu a to od váčkového plůdku až po ročka (jednoletou rybu) s možným výhledem do budoucna jako s tržní rybou. Také srovnávám poloumělý a umělý způsob výtěru. Krátce se zmiňuji i o chovu v zahraničí především Polsko a Německo. Navrhuji opatření na zvýšení produkce a uplatnění mníka na našem trhu jako konzumní ryby.

Napoleon´s theorem
MRÁZ, Luděk
The target of the this diploma thesis called ''The Napoleon's theorem'' is a detailed concentration on this theorem, where the process of so called ''regularization'' is described. Under the investigation of the Napoleon's theorem this diploma thesis is concerned with a lot of proofs, properties and then their generalization in a plane and in space. Pictures, which can help the reader to understand this problem are supplemented in this diploma thesis.

Use of paper folding techniques in teaching mathematics
MRÁZ, Luděk
The target of the Bachelor's thesis "Use of paper folding techniques in teaching mathematics" is to highlight the importance of origami in mathematics and its subsequent use as a suitable tool in lessons of mathematics in primary or in secondary schools. Most of the work is devoted to practical problems. It means constructions of planar and spatial figures and solving interesting or problematic tasks which are accompanied by graphics solutions and proofs.
