Procedures of the use and application of the biochemical preparations to the aquatic environment quality and water elements sediment state adjustment in the frame of cultural heritage management
Rozkošný Miloš ; Hudcová Hana ; Kratina Josef ; Sedláček Pavel ; Dzuráková Miriam
The monument procedure contains knowledge and instructions, which, according to the experience gained, should contribute to solving the unsatisfactory state of the aquatic environment in terms of water quality, excessive algae growth, increased turbidity, odor, and worsening conditions for fish life. This is usually associated with fluctuations in oxygen content and pH of water, the occurrence of toxic forms of metals, ammonia, etc. One of the parts is devoted to the possibility of the application of biological and biochemical preparations to reduce the organic component of sediments and reduce their volume. Recommendations are given for the survey of sediments, analysis of their composition, and determination of a suitable procedure for the application of preparations. Part of the monument procedure is documentation for the design and production of cultivation equipment for biological preparations (bioreactor), including description of its operation and maintenance.

Sustainability principles of fish stock of cultural monuments and historical settlements water elements
Adámek, Zdeněk ; Rozkošný, Miloš ; Hudcová, Hana ; Kratina, Josef ; Sedláček, Pavel
The object of the monuments procedure is to put into practice suitable and verified principles of composition of fish stocks of cultural monuments water elements, for production ponds and reservoirs, and for ornamental reservoirs, basins and pools. At the same time, it brings information about methods of fish stock management, principles of introduction of predatory fish, use of fish for biomelioration of aquatic environment. It also provides recommendations for the maintenance and care of farmed fish. To achieve this, it also includes a section aimed at identifying and describing an appropriate approach to solutions to improve water status, including water quality, and ensure the sustainability of fish stocks. Part of the monuments procedure is also a brief analysis of the issue of degradation of the reservoirs and ponds environment from the perspective of fish survival, due to pollution and water eutrophication. It also describes the individual causes of the unsuitable state of the aquatic environment.

Effective use RAS technolgy for breeding of ornamental fish in garden tanks.
MITÁŠ, Jaromír
The aim of this thesis was to evaluate the efficiency of the technology RAS for water cleaning and conditioning for ornamental tanks with an emphasis on sustainable conservation of water transparency. Initial costs for building the tank, operational costs and costs of purchasing fish were compared. Results include measurements that have been carried out on private property of the author, who breeds ornamental koi carp (Cyprinus carpio). The filtration of breeding tank was formed by vortex, by chamber with brushes, chamber with bioblocks and bioaquacitem. Tentative and 24 hours measurements of selected variables were used for data obtaining. The results indicate that the filter system is effective, but it had insufficient capacity. Transparency of water and elimination of glaucoma was solid by involving of UV lamp into the system of filtration. Available commercial resources were successfully used for controlling of filamentous algae. This thesis also includes a brief overview of ornamental fish species of our region, Moreover we mentioned the most common diseases, causative agents, symptoms and treatments. Overall, monitoring of the system of the garden's ornamental tank confirmed that water quality is dependent on the right choice and dimensioning of the filtration system and that current technology of recirculating of aquaculture systems can be successfully and effectively used within the construction and operation of tanks used for breeding of ornamental fish species.
