Will freshwater environments and fish populations benefit from the global COVID-19 pandemic and the resulting restrictions on the economy and society? Yes, in the short term, but probably not in the longer term – this is the conclusion of an international team of experts, including IGB scientist Robert Arlinghaus.

Researchers need data to generate scientific findings. Two new research methods – culturomics and iEcology – use the internet for this purpose. These approaches offer many opportunities, especially for the exploration of aquatic habitats.

Robert Arlinghaus' team has studied two predatory fish species, northern pike and European catfish, to determine whether the behavior and fitness of translocated fish differs from the behavior and fitness of the resident conspecifics.

On today's World Biodiversity Day: The natural species diversity of fished quarry ponds is at least as high, often even greater, than that of unfished comparative lakes. This is especially true for fish.

Germany’s highest award in science communication  goes to a knowledge disseminator for more sustainability in freshwater management and fisheries.

In addition to the offspring, also keep the particularly large, older specimens alive: This management achieves good compromises between the demands of professional and angling fishing and the natural reproductive capacity of fish stocks.   

Robert Arlinghaus has developed a method for combining the empirical knowledge of fishery stakeholders in such a way that the result corresponds to the best scientific understanding. This is of particular interest when human and financial resources are insufficient to achieve a profound scientific understanding or when, for example, fish stock data cannot be retroactively recorded.

Aquaculture is the fastest growing area of food production in the world – one of the reasons why it is the subject of controversial debate in society and politics. The information portal Aquakulturinfo.de provides objective and research-based information on aquaculture.
