In thestudy, published in Nature Food, the research team estimates that recreational fishing in lakes and rivers accounts for more than eleven per cent of the annually reported catches in inland fisheries worldwide. The analyzed total consumption value of harvested fish is around 10 billion US dollars per year. Due to climate change and direct human impacts on freshwater ecosystems, the productivity of important fish species such as trout and salmon is declining, affecting the nutritional services offered by rivers and lakes.

Together with Dr Jörn Gessner from IGB and the Director of the Lower Oder Valley National Park, Dirk Treichel, Federal Environment Minister Steffi Lemke today released 600 sturgeons into the Oder River near Criewen. The new home of the young fish is a special habitat, as the Oder is the last major river in Germany where sturgeon and other animals can migrate unhindered over long distances. Since 2006, it has been a priority area for the reintroduction of the Baltic sturgeon.

In order to protect lakes from chronic diseases and threatening conditions and to heal them, strategies similar to those used in human healthcare should be applied: Prophylaxis, regular screening, treatment and mitigation on a local to global scale.

A new IGB manual makes knowledge about the construction methods and authorisation requirements for Vertical Wetlands publicly available to interested parties.

From as yet undiscovered biodiversity and resilient forests to the impact of food consumption on nature: 64 experts, including many IGB researchers, have published the "10 Must Knows from Biodiversity Science" for 2024. With the new report, the Leibniz Research Network Biodiversity provides policymakers and society with concrete ways to effectively conserve and sustainably use biodiversity at the local, national, and European levels and thereby also mitigate climate change.

Aquatic microorganisms in China's Yangtze River are particularly resistant to many antibiotics, posing a high health risk. This is the result of a study by a Chinese research team in which IGB scientist Professor Hans-Peter Grossart was involved.

Die Zahl großer Süßwassertiere wie Störe, Riesenwelse, Flussdelfine, Flusspferde, Krokodile oder große Schildkröten ist weltweit stark zurückgegangen, ebenso wie die Größe ihrer Verbreitungsgebiete. Die Ursachen für die Gefährdung dieser Megafauna sind weitgehend bekannt, die Folgen des Verlusts für die Ökosysteme dagegen kaum.

Fish are changing how they search for and consume prey in warmer waters, with models suggesting extinctions become more likely due to this behaviour change. This is the result of a new study led by researchers from the German Centre for Integrative Biodiversity Research (iDiv) and the Friedrich Schiller University Jena, with the participation of IGB, published in "Nature Climate Change".
