Lo Persson
I have a general interest in biology and ecology and I find the academic working environment extremely stimulating and rewarding. The title of my PhD thesis is "Effects of feeding regimes on phenotype and performance in Atlantic salmon", which I defended in November 2017. I'm the mother of two sons and I like an active and outdoorsy spare time.

Presentation

My research profile

My research is focused on aquatic ecology and migrating salmonids. During my PhD education I worked with hatchery-reared Atlantic salmon and studied effects of different feeding regimes on the phenotype, the smolt migration, and the adult return rates. At the moment I’m involved in work related to monitoring of sea trout in the Baltic Sea. I’m really fascinated by the life history of those two species and I would like to know more about what factors determine if they succeed and how long they stay at sea before they return to freshwater to spawn. I’m also interested in the health status of salmon and questions related to the 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. I’m a big fan of teamwork, and when it comes to publishing I really appreciate discussing results and theories with my colleagues 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.

 

Undervisning

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.
