Main goals

The main goal of the project is to contribute to the development of decision tools that could allow us to monitor and predict the impact of harvesting on fish stocks in freshwater reservoirs. These tools will be based on data, gathered on the history of exploitation in selected water bodies in southern and central Bohemia with Lipno Lake as the main case study, and on mathematical models and computer simulations. This can provide feedback to the management and environmental authorities as to how the procedure of collecting and processing of data can be improved in the future.

Main project objectives

• Data analyses

• Compilation of a database of past exploitation and fish population dynamics in selected water bodies in the Vltava river basin, based on angler's logbooks, published reports and other gray literature, with Lipno Lake as the main case study (activity 1.1).
• Use of statistical analyses to search for patterns that could unravel the underlying ecological and evolutionary processes behind the changes in fish populations and their characteristics (such as mean size of fish in the catch) (activity 1.2).

• Modelling

• Application of mathematical models on optimal exploitation strategies and stakeholder interests in marine fish stocks and their adjustment to describe the situation in the study area (activities 2.1-2.3).
• Application of mathematical models on evolutionary consequences of fishing in marine stocks and their adjustment to describe selected species in the studied reservoirs (activities 3.1-3.2).

• Outreach and dissemination of result

• Exchange and transfer of knowledge on mathematical models and advanced statistical analyses of fisheries data between the teams in the Czech Republic and Norway (activites 4.1-4.4).
• Organization of the international symposium DINFISH2010 to further strengthen collaborative links and promote the research topic for a wider scientific and stakeholder audience (activities 5.1-5.3).
• Communication of expert advice on sustainable exploitation of fish to key stakeholders identified during the study in order to improve the procedures used in environmental monitoring of Czech reservoirs (activities 1.3, 2.1, 2.3).
