We study fish reproduction, eco-physiology, the development from the embryo to the juvenile in the River Danube and its tributaries. There we also investigate fish biodiversity, migration and habitat selection and habitat use of fish assemblages and single species. Applied methodologies are standard fisheries techniques (active and passive) and high frequency multi-beam sonar.
