Research Summary

My research focuses on the factors controlling fish production in Arctic lakes.  In my PhD-project I am working towards the ultimate goal of contributing to a sustainable and effective management of Arctic lake fish populations in a changing climate.

Project Summary

adaptive management of arctic lake fish populations

The main objectives of the project are to 1) increase understanding of factors controlling biomass production in Arctic lakes, 2) to develop novel methods for monitoring climate change, and 3) to develop new management strategies that ensure sustainable use of Arctic lake fish stocks. This will be accomplished by studying lakes in the Jämtland, Västerbotten and Norrbotten counties in Sweden. The work includes measuring different chemical and physical parameters, the production of algae and estimations of fish biomass and production. Within this project we will also develop new methods for discovering changes in light availability, algae and fish production as well as new statistical models for a rapid detection of changes in lake productivity and fish population dynamics.
