Sustainable aquaculture with a responsible water and nutrient management  


Head of the research program: Dipl.-Ing. Jan Mráz, PhD.

The research team of the RP 3 consists of selected employees from 2 research institutes. These will be employees of 7 scientific laboratories of the FFPW USB, specifically the Laboratory of Nutrition (LN), the Laboratory of Controlled Reproduction and Intensive Fish Culture (LCRIFC), the Laboratory of Applied Hydrobiology (LAH), the Laboratory of Lipid Metabolism (LLM), the Laboratory of Aquatic Toxicology and Ichtyopathology (LATI), the Laboratory of Signal and Image Processing (LSIP) and the Laboratory of Intensive Aquaculture (LIA). Next, it comprises employees of the Department of Ecosystem Biology (DEB) of the Faculty of Science, University of South Bohemia and employees of the Department of Hydrochemistry and Ecosystem Modelling (HEM) and the Department of Aquatic Microbial Ecology (AME) of the Institute of Hydrobiology, Biology Centre CAS.


The world fish consumption has been constantly rising thanks to the growth of human population and information about positive effect of fish on human health. Demand for fish has been satisfied primarily through freshwater aquaculture production. From the worldwide point of view, aquaculture has become the fastest growing animal production industry in the past 50 years with an annual production growth of around 8%. At present, it has covered more than 49% of fish supply for human consumption. It is expected that by 2050, human population will increase to 9 billion people. Such sharp increase will raise demand for foodstuffs and water and subsequently for feed and fertilizers. In order to cover the existing fish consumption, it will thus be necessary to increase the aquaculture production at least by 60%. In the Czech Republic, aquaculture has almost a thousand-year-old tradition and thanks to its historical legacy in the form of pond resources, it has mainly focused on pond fish farming. Due to increasing requirements for the environmental conservation, it is supposed that fish pond production has achieved its top level and the fish production growth will be implemented through intensive aquaculture. According to the National Strategic Plan for Aquaculture, the increase in the fish production will be achieved mainly by establishing new recirculation aquaculture systems. By building new recirculation farms and pressure exerted on ecological fish production, an increased demand for know-how, technologies and innovative solutions leading to sustainable and diversified aquaculture will emerge. The objective of the proposed research programme is to support freshwater fish farming through a technical and biotechnical innovation which will enable this sector ecological, efficient, balanced, varied, continuous and quality production of fish and their products.

The vision of the research programme is the aquaculture as the future solution for maximum production of quality foodstuffs for 9 billion people with minimum consumption of water and energy, minimum production of waste matters, minimum “food miles” and minimum competition for resources with consumption of people and farm animals. Next objective is that the aquaculture industry, which is dependent on supply of fish from oceans and pollutes aquatic resources, would become an industry independent on sea fishery and which consume more waste products than it creates.
Objective of the RP

The objective of the research programme is to develop technologies enabling maximum use of nutrients, wastes, including municipal waste of a vegetable and animal origin, and energy for production of fish and plants with minimum released waste products and greenhouse gases into the environment. Key outputs of the RP will be mutually connected technologies for production of fish, plants and other organisms with treatment and use of waste which will enable maximum use of nutrients directly on an aquaculture or aquaponic farm with minimum released waste products into the environment. Results will have a significant impact for the entire society mainly for ensuring enough high-quality foodstuffs, minimization of production of greenhouse gases, use of waste, decrease in food miles and thus decrease in fossil fuels, decrease in water consumption and production of waste, decrease in water eutrophication and reducing dependence of aquaculture on fishery.

Results of the experiments and studies achieved by the research team have been continuously published and the emphasis has been put on publication of applied results in scientific journals, monographs and scientific publications. A highly important activity of the research team is represented also by commercial activities generating significant financial resources. Since 2010, members of the research team have implemented 15 contracts in total relating to a contractual research within a direct consultancy or innovation of fish farming with total revenues exceeding CZK 15 million.
