(Dept. 4) Fish Biology, Fisheries and Aquaculture
In the Department of Fish Biology, Fisheries and Aquaculture we seek to understand the ecological and evolutionary processes that structure populations and communities of freshwater fishes and affect their functions and ecological services. An important part of our work focuses on interactions between natural and anthropogenic factors and their effects on evolution, reproduction, stress, development, growth, behaviour, productivity and recreational quality of fish. Our goal is to create the scientific foundations for the conservation of wild fish populations and for sustainable fisheries management and aquaculture. The methodological approaches include hypothesis-driven laboratory research, mesocosm experimentation, lake manipulation, comparative field studies and theoretical modelling.

Evidence for a by-product mutualism in a group hunter depends on prey movement state
Researchers from the Cluster of Excellence Science of Intelligence (SCIoI), in which the Humboldt-Universität zu Berlin (HU Berlin) and the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) are involved, have proven in an underwater field study in the ocean off Mexico: the faster a school of prey moves, the higher the capture rate of the striped marlin.
Freshwater megafauna shape ecosystems and facilitate restoration
This is a review, synthesizing how megafauna shape ecological processes in freshwater ecosystems and discussing their potential for enhancing ecosystem restoration. Restoring freshwater megafauna can revive essential ecological processes like disturbances, trophic cascades, and species dispersal, boosting biodiversity and enhancing nature's contributions to people.
A global systematic map of knowledge of inland commercial navigation effects on freshwater ecosystems
The authors conducted a systematic mapping of the published literature (1908–2021) to provide a global synthesis of the effects of inland navigation on the biotic and abiotic components of freshwater ecosystems. Inland navigation impacts rivers through shipping, infrastructure, and waterway management, causing direct (e.g., waves) and indirect effects (habitat loss, invasions).
The European Reference Genome Atlas: piloting a decentralised approach to equitable biodiversity genomics
Researchers from all over Europe have created high-standard reference genomes for 98 species as part of the European Reference Genome Atlas (ERGA) pilot project. This collaboration of scientists from 33 countries is an important milestone on the way to a reference genome database for European animals, plants and fungi.
The global extent and severity of operational interactions between conflicting pinnipeds and fisheries
Conservation efforts have led to the recovery of pinnipeds populations worldwide after decades of intensive hunting and culls. However, this positive development has led to conflicts with fisheries, particularly small-scale fisheries. They are almost three times more likely to come into conflict with seals, sea lions and walruses, and lose four times more of their catch than larger fisheries.
