My research profile
My research is focused on aquatic ecology and migrating salmonids, in particular Atlantic salmon. During my PhD education I studied effects of different feeding regimes on the phenotype; the smolt migration; and the adult return rates, in hatchery-reared Atlantic salmon. After attaining my doctorate I hope to include more wild fish and also expand the scope to what is happening with the fish in the sea. What determines how they succeed and how long they stay in the sea before they return to their home river? I’m also interested in the health status of salmon and questions related to their downstream and upstream migration in regulated rivers.
I’m used to handling fish, mainly juveniles, and I have tagged a few thousand fish with PIT-tags and a few hundred with acoustic tags (surgical implantation). During my time as a PhD student I worked closely with other people at the university as well as the staff at the hatchery and various field technicians and I’m a big fan of teamwork. When it comes to publishing I really enjoy discussing results and theories and I enjoy writing.
I like to pursue a carrier as a scientist and my goal is to increase the knowledge about migrating fish and contribute to the conservation of species and related ecosystem services.
I have given lectures both at the undergraduate and master level here at SLU and elsewhere. Topics that I have covered are related to fish and wildlife census techniques (including handling and tagging of fish), and to fish farming and aquaculture.
