I coordinate activities at the Baltic Sea Science Center, developed by Skansen together with a team of experts (Kunskapsrådet) from SLU, Stockholms University and Stockholm Vatten och Avfall.
I am currently involved in research projects with focus on:
- National collaboration of Salmon health (reproductive disease, M74 & Red Skin Disease).
- Production and transport of algal toxins in the Baltic Sea environment.
- Development of tools for non-invasive monitoring of fish health.
I am engaged in teaching activities within the courses:
- Assessment and Advice on the Principles of Fisheries Science
The health situation for our native salmon is worrying, both in the Atlantic and in the Baltic Sea. Disease outbreaks (bleedings, erythema’s and fungal infections) along with well-studied reproductive disorder (M74), is reported by most Nordic countries. The reason(s) behind the failing salmon health are unclear and it is not known how the various symptoms are related. In spite of its iconic status, little effort have been put into studies of wild salmon diseases. Large-scale assessments and monitoring studies are key for research and monitoring efforts to shed light on the magnitude and cause of the deteriorating salmon health. With grants from the Nordic Council of Ministers (2021 – 2023), The Nordic collaboration network on salmon health, aim to strengthen collaboration within salmon health issues among the Nordic countriesromotes through networking and pilot studies.
Algal toxins and thiamine deficiency in the marine food web
Previous findings on toxic effects following exposure to algal toxins and thiamine deficiency in key species of the Baltic Sea food web require pursuit. This autumn, We aim to initiate study of spatiotemporal variations of algal toxins in pelagic mussels with the overall ambition to develop new tools for monitoring of concentrations.
I am the project leader of national monitoring programs of Baltic Sea salmon and responsible for coordinating the monitoring of reproductive disease, M74, in salmon and thiamine (vitamin B1) in salmon.
