Fish migration

Karlstad University is pleased to announce the doctoral defence of Samuel Shry, entitled “Anadromy in Fragmented Rivers: Downstream Passage Challenges for Migrating Salmonids.”

The defence will take place on 20 February 2026 at 10:00, in Sjöströmsalen (Room 1B309) at Karlstad University.

In his doctoral research, Samuel Shry investigates how river fragmentation affects downstream migration of anadromous salmonids. With a particular focus on migration barriers and passage challenges, the thesis contributes important insights into fish ecology, river management, and conservation strategies in regulated river systems.

The appointed opponent is Senior Research Scientist Line Sundt-Hansen from the Norwegian Institute for Nature Research (NINA), Norway.

The defence is open to the public, and colleagues, students, and interested members of the wider research community are warmly welcome to attend.

Daniel Nyqvist from Politecnico di Torino will be giving a seminar entitled Fish movement and behavior in industrial waters – electromagnetism, noise and ecohydraulics on Tuesday 31 May 2022 at 13.15 CEST over zoom https://kau-se.zoom.us/my/kaubiology.

Daniel’s current research focuses on fish behavior and ecology in regulated rivers. Also, he is interested in movement ecology, effects of acoustic noise and electromagnetism on fish behavior, conservation, and the connections between ecology and socioeconomics.

You are welcome to join this seminar.

Dr. Erin McCallum, a researcher at (Forskare) at SLU in Umeå will be giving a talk about waterwater effluents and salmonid migration in freshwaters on Tuesday 5th April at 13.15 CET over zoom. Erin is a behavioral ecologist and ecotoxicologist interested in understanding the causes and consequences of anthropogenic stressors for aquatic wildlife. Erin’s seminar is entitled “A tale of two research programs: Wastewater effluents and salmonid migration in freshwaters”. She will present her current research on wastewater effects on fish communities and the migratory success of anadromous brown trout smolt. You can visit Erin’s page to read more about her research interest.

You are welcome to join this seminar free of charge via https://kau-se.zoom.us/my/kaubiology.
