Department Fish Ecology and Evolution

Fish Ecology & Evolution (FishEc)

We study ecology, evolution and biodiversity of fishes and other aquatic organisms. We are interested in the mechanisms that drive the origins, the maintenance and the loss of species, genetic and functional diversity.

In a survey of Swiss rivers and streams, more than 50 different fish species were recorded. For the first time, more than one species was also found in the case of smaller types of fish such as the bullhead.

Biologists at Eawag have identified ten species of whitefish in the lakes of the Reuss river system. Of these, seven have been described as distinct species for the first time – although in two cases this required inspection of specimens from historical collections, since eutrophication of lakes in the 20th century also led to the extinction of fish species in Central Switzerland.

Research Projects

Establishing a framework for conservation genomics of freshwater biodiversity
We study the biodiversity of Swiss freshwaters and design data-driven conservation strategies that take climate change and human impacts into account.
In this project we are interested in which traits govern the efficiency of stickleback foraging in different ecological contexts.
This project contributes to the Blue Green Biodiversity Research Initiative
