Researchers explain the ecological developments in Lake Stechlin and the latest findings in a new IGB Dossier. In it, they also provide an assessment of which follow-up actions now appear appropriate.

Dr. Timo Rittweg , former doctoral student at IGB, was awarded the “Forschungsstiftung Ostsee” Research Prize for his doctoral thesis. In his dissertation, he studied the life of pike in the Bodden off Rügen as part of the BODDENHECHT project. 

Whether a caught fish is released back into the water or removed for consumption depends on more than just the fish species and size. Researchers from IGB have analysed the role of anglers' personal characteristics and the influence of the fishing context in a diary study.

Internal clocks can tick very differently. While some people are most productive in the morning, others are only active later in the day or at night. This phenomenon is known in science and medicine as chronotype. In a comprehensive analysis of the activity patterns of wild fish, a research team involving the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) has shown that fish – carp, trout, zander, and others – also have individual early and late risers. The results were published in the journal Fish and Fisheries. 

A new joint Policy Report by the German National Academy of Sciences Leopoldina and the Brazilian Academy of Sciences (Academia Brasileira de Ciências, ABC), to which IGB researchers also significantly contributed, shows what sustainable and circulation-orientated aquaculture could look like in Germany and Brazil.

Today on Earth Day, the 19 National Champions of the Frontiers Planet Prize, a globally significant research prize for sustainability, were announced. Robert Arlinghaus, Professor of Fisheries at the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) and the Humboldt Universität zu Berlin, and his team are recognized for their groundbreaking publication in Science on the effectiveness of habitat improvement on fish populations in lakes.

The brackish lagoons around the German island of Rügen in the southern Baltic Sea are known as outstanding fishing areas, especially for large pike. However, pike catches and catch sizes have been declining for several years.  There are many reasons for this: loss of spawning grounds, decline in nutrition, increased natural mortality due to cormorants and other natural predators, climate change and overfishing.

The Stifterverband has honoured two outstanding Leibniz researchers from Berlin with the ‘Research in Responsibility’ science award. IGB researcher Robert Arlinghaus shares the 40,000-euro prize with Lena Hipp from the WZB Berlin Social Science Center.
