IGB’s topics in a nutshell

Welcome to our world!

Water consists of only two chemical elements – and yet the subject of water is infinitely diverse. Since everything we do at IGB is associated with water, our work is likewise very varied. Examples of the topics we explore include the use of freshwaters, exposure to contaminants, and aquaculture. To give you easy access to everything that may interest you concerning our research activities, we have structured this information into ten thematic areas. For each topic, the relevant news reports, events, projects, publications, materials and details on who to contact are clearly arranged together in these thematic areas.

Integrating academic research with stakeholder knowledge and experience contributes to sustainable fisheries management.

Aquaculture and aquaponics

We explore environmental, economic and social aspects of sustainable aquaculture.

Behavioural ecology and swarm intelligence

Social networks and collective decision processes are not only interesting for ecology, but also for decision management in politics, medicine or the economy.


Freshwaters are some of the most species-rich habitats on our planet. One important objective of our research is to protect their biodiversity as effectively as possible.

Dialogue and transfer

The provision of information and objective consulting to social players from policy, authorities, associations, the economy and the interested public is an important task undertaken by IGB.

Environmental change

Lakes and rivers react extremely sensitively to climate change and environmental changes. As such, we use them as an early warning system for global ecological change.

Freshwater ecosystems

Ecosystems are equally important as habitats and resources. We explore the underlying processes and interactions.

Multiple stressors and pollutants

Freshwaters are used intensively by humans, meaning that they are exposed to a number of stressors. We explore the complex interrelations and impacts of multiple stressors.

Use and management

Freshwaters are used in many ways. All these functions can only be ensured if rivers and lakes are in a good ecological state. We develop concepts for the future-oriented management of freshwater resources.

Water and matter cycles

Rivers, lakes and wetlands connect the land to the sea, they are directly linked to groundwater, and regulate the global nutrient and carbon balance.
