Water is crucial for all living organisims that covers almost 80% of our planet. Although productivity of water resources unproportionally distributed, all of them host vast biodiversity but only very minor part in freshwaters is available for human life. Aquatic life in these ecosystems are progressively threatened by invasive species, climate change and habitat destructions mainly through anthropogenic pollution, water abstraction, unpredictable fluctuations in water level and invasive species. All these impacts interact and enhance uncertainty about the availability of aquatic life.
Our most important goal is to ensure a sufficient supply of good-quality aquatic life and water for future generations. However, the maintenance and management of aquatic ecosystems require the close cooperation of scientists, politicians and stakeholders, and must arise from the best available knowledge and experience provided by ecologists. We hope that the first symposium on Marine and Freshwater Sciences will be an ecosystem based symposium including also studies on protected areas, tourism economy, energy, natural sources, and education and offer an opportunity to bring together experts from various disciplines and contribute substantially to increasing our knowledge of the theoretical and practical aspects of marine and freshwater sciences.
