Autonomous system for control of aquarium
Charvot, Jakub ; Levek, Vladimír (referee) ; Tomíček, Pavel (advisor)
This thesis delves into the topic of aquarium automation, aiming to design custom system for this purpose. The essential technology requirements for efficient aquarium operation are summarized at the beggining followed by the market survey with depiction of existing commercial solutions in the field of automation. Regarding the practical part, the thesis explain the design process of the device and takes a deeper look at its crutial steps. System architecture is disccused as well as the creation of electrical schematics, and the design of custom printed circuit boards. The final part of the text is dedicated to the software. The outcome of the thesis is a modular system consisting of a control unit and several connected peripherals managing specific sensors and actuators. The entire system can be configured remotely via a web application.

Fully analog aquarium for growing tropical plants
Domanský, Ondřej ; Šotner, Roman (referee) ; Petržela, Jiří (advisor)
The aim of the thesis will be to clarify issues relating to the cultivation of tropical plants in aquariums. The main aspect of the work is to analyze the ideal environment for the home aquarium and the choice of specific components for plant growth. In the next sections will illustrate also the proposal of such a system and its implementation in ambient conditions.

Smart aquarium management system
Musil, Libor ; Kvíčala,, Radek (referee) ; Hudcová, Lucie (advisor)
This bachelor thesis deals with the design of an intelligent aquarium management system. The system is going to be based on the i.Mx8DV platform with graphical output on the touch screen. In the thesis, the methods of measuring and controlling the quantities, that are critical for the proper operation of the aquarium, are discussed. Also, the i.Mx8DV platform and the Neutrino operating system are described. This thesis solves the selection of suitable sensors and design of printed circuit board for connection of the i.Mx8DV platform with selected sensors. The principles of network communication and web server implementation options are described. In the end, the application is described.

An Aquarium as an Ecosystem Suitable for Ethological Observations of Fish
Mejstříková, Lucie ; Hanel, Lubomír (advisor) ; Andreska, Jan (referee)
Aquaristics is a very widespread hobby not only among adults, but also among children. However, the aquarium may not only serve as an decorative and relaxing element, but also as a teaching tool. Through project-based learning, the ethology of fish, for example their orientation in space and time in relation to where they feed or their epigamous and social behaviour, can be studied there. The success and failure of fish farming and plant cultivation points to the imbalance of minerals and substances in the water, so it is important to take into account their cycling in the aquarium. This paper describes how to set up and care for an aquarium and it also provides various recommendations. To illustrate the cycling of substances, energy and matter, simple diagrams have been created that can also be used in ecology lessons. In the practical part, the biology of model aquarium fish has been described, accompanied by many photographs. In the didactic part, worksheets were designed - one to serve as a basis for project-based learning, the other for data analysis. The effectiveness of the worksheets was verified in the sixth and eighth grade of a primary school. Since the first worksheet had very low return and was frequentely misunderstood the second worksheet was created. This one was less time consuming...

Prediction of invasive marbled crayfish (Procambarus fallax f. virginalis) global spread
Nováková, Pavla ; Patoka, Jiří (advisor) ; Antonín, Antonín (referee)
Biological invasions are currently a global problem. They often cause a loss of biodiversity and severely disrupt the balance of entire ecosystems. One of the most dangerous among the many species of crayfish known to be invasive is the marbled crayfish or Marmorkrebs (Procambarus fallax f. virginalis Martin et al., 2010).
The marbled crayfish is a major ornamental crayfish species. It is a known vector of infectious crayfish plague, which is lethal for crayfish species of non-North American origin. Marbled crayfish is also very tolerant to different water temperatures. The most important feature making it an especially dangerous invasive species, is the way of its reproduction. Marbled crayfish reproduces via apomictic parthenogenesis. Therefore, only females are able to reproduce and males of this taxon has not been recorded. This crayfish is characterised by a very quick maturation and extremely rapid growth.
Even though some established populations of this taxon in the wild have already been recorded, and probability of the establishment in selected regions was evaluated, no predictions for expansion on a global scale have been conducted.
The program CLIMATCH was used in this thesis to match the climate conditions between the source area (distribution of established populations of marbled crayfish in the wild) and target areas (all continents excluding Antarctica) based on temperatures during the coldest and warmest quarters of the year.
The results showed that marbled crayfish can probably survive and reproduce in even colder regions of the temperate zone. The presented findings additionally indicate that temperate zones contain slightly higher potentially suitable regions than in the case of tropics. There are temperature conditions most suitable for the survival and reproduction of the marbled crayfish within Europe in comparison of the rest of the world; and the least favourable temperature conditions are within Australia.
The marbled crayfish introduction and ability to survive and reproduce in the wild is a potential threat to native biota and entire ecosystems on all continents assessed. Therefore, it is strongly recommended that the breeding of and the pet trade with this crayfish should be regulated by policymakers and wildlife managers by improvement of legislative restrictions (such as in the EU) and intensive future education of general public. It is obvious that the monitoring of invasive crayfish species might be continuous. Nevertheless, the most important step is to make producers and hobbyists aware of the risks related with marbled crayfish.

History, development and present breeder trends in aquaristics
Kučerová, Kateřina ; Hanel, Lubomír (advisor) ; Andreska, Jan (referee)
History, development, and present breeding trends in aquaristics The presented diploma thesis is based on empirical research, and deals with the history, development, and current trends in aquaristics. The theoretical part is focused on qualitative content analysis of relevant specialized literature. This thesis defines history and development of aquaristics in the world, as well as in our country, and compares current and past aquarium equipment and methods. In this work are presented and described current trends in modern aquaristics. The text is complemented by contemporary drawings and layouts of historical and recent equipment and technology. The research part is focused on data obtained from quantitative content analysis of aquarium publications, where is observed frequency of mentions in the text of particular species of aquarium fish. At the same time the results are compared with the content analysis of statistical data of aquaristics portals aimed at the real preferences of breeders. From the conclusion results that in their articles the authors preferred some of the selected families in each of the examined periods. Most preferred family was Cichlidae, Characidae and Cyprinidae. However, often presented species of aquarium fish do not correlate with the real preferences of modern...
