Internship in Fish ecology/Fish migration

Updated: 4 months ago

Eawag, the Swiss Federal Institute of Aquatic Science and Technology, is an internationally networked aquatic research institute within the ETH Domain (Swiss Federal Institutes of Technology). Eawag conducts research, education and expert consulting to achieve the dual goals of meeting direct human needs for water and maintaining the function and integrity of aquatic ecosystems.

The Department of Fish Ecology and Evolution (FishEc) located in Kastanienbaum (Lucerne) has a vacancy for an

In the research group ‘River Fish Ecology’, we study the ecology and evolution of fish in riverine eco-systems. We work mainly at the interface between ecology and evolution and realize repeatedly that these two traditionally separate disciplines are interdependent. More specifically, we are working on adaptation, fish migration and river fish biodiversity at the genetic, phenotypic and community level. The overall objective of our work is to understand the interactions and potential feedbacks between ecology and evolution.

We are looking for an intern to work on research projects on migratory fish. We are working with lake-ward migration of trout across all larger Swiss lakes and their tributaries and on anadromous Arctic charr from several fjords and their tributaries in Southern Greenland. Lastly, we are starting up movement and migration studies on larger fish in the Rhine/Aare River network.

Prerequisite for the application is the enrollment at a university or college, ideally degree program Biology, Environmental Sciences, Environmental Engineering etc. (bachelor or master's degree, but not yet completed).

Your responsibilities are predominantly support during fieldwork and laboratory analyses of samples from migratory fish. The fieldwork may include participation in installment of acoustic receivers in rivers, electrofishing, tagging of fish and additional monitoring of fish migration. Laboratory work may include stables isotope analyses, stomach content analyses, morphological analyses and molecular analyses.

Time period: between September 2023 and April 2024. Start and end date of the internship is flexible and duration of internship is between 4 and 6 months.

The main work place is at Eawag’s Center for Ecology, Evolution and Biogeochemistry (CEEB) in Kastanienbaum, Lucerne, which besides the Fish Ecology and Evolution Department hosts research group from the Department Surface Waters – Research & Management and offers a beautiful workplace at the shores of Lake Lucerne, a friendly international working climate and a strong cross-disciplinary research environment. Both departments within CEEB share a common interest in understanding the principles of the functioning of aquatic ecosystems and their susceptibility and adaptability to changing environments, and a common concern for sustainable management of ecosystems and biodiversity.
