Intenzivní chov okounka pstruhového (Micropterus salmoides) v RAS s různým světelným režimem

BOŇKO, Dominik January 2019 (has links)
Largemouth bass (Micropterus salmoides) is one of the species of fish that don´t have a significant position among the species of fish breeded in Czech Republic. However the trend of building aquaculture recirculation systems with warm water comes to the fore. Breeding in these conditions opens up the possibility of introducing new kinds of thermophilic fish species. Largemouth bass definitely belongs to this group. The general factors of successful breeding of largemouth bass are the temperature and purity of the water, the suitable-composed diet and the correct stocking density. This work studies another factor that not only participates in the success of the breeding, but also has influence on the energy expenses of the aquaculture system. It is the effect of photoperiod during breeding. Five experimental groups with three repetitions were created according to the time of lighting (8, 12, 16, 20 and 24 hours of light a day). The experiment lasted 16 weeks. The average water temperature was 24,6 °C. The initial stocking density for all tanks was 20.6 kg . m-3. Fish had an initial average weight of 32.6 +- 2.1 grams. The feed ration was set up at 1% of biomass per day. As a diet were used a floating dry pellets Skretting R-2 Europa 15 F of 2 mm. The feed contained 55 % of protein and 16 % of fat. Fish were fed manually by hand. All groups showed high survival during the experiment (99.4 - 100 %). The best results were achieved by a group of 8 hours with the highest feed conversion (FCR = 0.94 +- 0.06) and the highest growth rate (SWGR = 0.6 +- 0.04 % . day-1). The average individual fish weight of the 8 hour group at the end of the experiment was 64.07 +- 2.82 g. On the other hand, group of 12 hours was the worst with the lowest average individual weight (W= 57.51 +- 1.51 g), growth rate (SWGR = 0.49 +- 0.04 % . day-1) and the lowest feed conversion (FCR = 1.16 +- 0.08). These two groups were significantly different in most production indicators. The pervisceral fat index grew with biomass. The longer the photoperiod, the higher the plasma and ammonia content of lactate. In contrast, glucose content decreased. A longer photoperiod also influenced the higher production of antioxidants.

Vývoj struktury volných pracovních míst ve vztahu k ekonomickému růstu / Development of Structure of Vacancies in Relation to Economic Growth

TALÍŘOVÁ, Lucie January 2011 (has links)
This thesis deals with development of structure of vacancies in relation to economic growth. Objective of the thesis was to assess the development of vacancies in terms of economic growth in the selected region. The thesis was divided into theoretical and practical part. Terms regarding the given issues were clarified in the theoretical part. This part also deals with offer, demand and balance on the labor market, unemployment, employment policy, economic growth ? it´s measurement and patterns. The region České Budějovice, which will be further discussed in the thesis, is characterized in the first chapter of the practical part. The thesis answers the question, what the unemployment rate, number of job applicants or number of vacancies in the region is. It also deals with the structure of vacancies according to education, profession or length of vacancy and on the other hand it deals with the structure of job applicants according to sex, age, profession or length of unemployment. The effect of economic growth on the structure of jobs is assessed in the next chapter. There´s a certain mismatch between the structure of vacancies and the structure of the unemployed. Main problems of this mismatch are defined in the final chapter of the practical part. There are an overall summary of the results and recommendations for the future in the conclusion of the thesis.

Chov lamy krotké v ČR / The breeding of llamas in Czech Republic

KREJNÍKOVÁ, Sandra January 2011 (has links)
During the past few years a development of breeding llamas and alpacas took place in Czech Republic. Increasing interest in those animals entails the need to determine how they respond to the conditions of our country. The aim of this thesis is to evaluate the growth ability of crias, some of the physical dimensions (withers height) and bodyweight of adult llamas. The same indicators are to be evaluated for alpacas as well. The results are to be compared with the standard for llamas and alpacas. A total of 104 animals were measured and weighted, namely 44 llamas and 60 alpacas, and 280 pairs of weight and height data were obtained. Weighing and measuring of adult llamas and alpacas took place once a year around the end of August for two years (2009 and 2010). Young llamas were weighed and measured at approximately monthly intervals according to the possibilities of their breeders. Young alpacas were weighed at approximately weekly intervals. The thesis is divided into two parts. The first part evaluates llamas. It was discovered that the average birth weight of llamas in the Czech Republic is 11 kg. Once mature, they reach an average live weight of 130.3 kg and average height of 110.2 cm. Average daily gains were observed as follows: from birth to 7 weeks 0.20 kg per day, from 7 weeks to 24 weeks 0.18 kg per day and from 24 to 72 weeks 0.13 kg per day. The second part of this thesis is devoted to alpacas, for which the same parameters as for the llamas were monitored. It was found that the average birth weight of alpacas in the Czech Republic is 6.5 kg. Once mature, they reach an average live weight of 65.6 kg and average height at 88.4 cm. Average daily gains are at the following levels: from birth to 7 weeks 0.1 kg per day, from 7 weeks to 24 weeks 0.09 kg per day and from 24 weeks to 72 weeks 0.08 kg per day. It was found that these two species reach final physical maturity later in the Czech Republic than stated by literature. Compared to the standard, most of the llamas and alpacas are up to their standards.

Vybrané aspekty intenzivního chovu síha marény (Coregonus maraena, Bloch) a peledě (Coregonus peled, Gmelin)

ŠEBESTA, Roman January 2018 (has links)
Maraena whitefish and peled are considered to be economically important fish species. This Ph.D. thesis deals with testing of selected aspects which show potential for improvement of quality and effectivity of larvae and juveniles of both fish species in recirculating aquaculture systems. The whole Ph.D. thesis includes 9 chapters described in 125 pages. In chapters 2-8, there are described the individual factors which can influence quality of intensive rearing of mentioned fish species. The effect of light intensity and tank wall colour on growth and survival of peled larvae is tested in chapter 2. The effect of different temperature on growth and survival of maraena whitefish larvae is presented in chapter 3. The effect of various stocking density on growth and survival of maraena whitefish larvae is given in chapter 4. The influence of different feeding strategy on survival, growth, and intestine and liver development of maraena whitefish larvae is being shown in chapter 5. The effect of various weaning time and co-feeding duration on growth and survival of peled larvae is described in chapter 6. The effect of variable water oxygen saturation on growth and haematological profile of peled juveniles is shown in chapter 7. The prevalence of deformities in intensively reared peled and comparative morphometry in intensively reared fish compared to pond-reared fish is described in chapter 8. Ph.D. thesis contains important advices which can be used in fishery practise and at the same time they can prevent from elevated fish mortality.
