Katja Enberg – Group leader

I am an Associate Professor in Fisheries Science, and in my research I use modelling tools to understand patterns observed in nature. I am interested in trying to understand the mechanisms that cause differences in for example life histories and population dynamics. I am very interested in what happens with nature now that we have entered the Anthropocene. Multiple stressors such as harvesting and climate change may lead to unexpected consequences for the marine and terrestrial populations and ecosystems. I have been working with contemporary human-induced evolution, particularly fishing-induced evolution and often combine this with fisheries management problems. I strive to find out what are the combined effects of human harvesting and changing climate for individual phenotypesgenotypes, life-history strategiespopulation-level processes, and ecosystem services? And what can we do to achieve the UN Sustainable Development Goals, in particular the SDG14: Life below water?


Henrik H. Jessen – PhD-student

My PhD project aims to assess the rate and direction of evolution in the North East Arctic (NEA) Cod stock, when accounting a combination of climate changes and fisheries pressure. This knowledge will help managers and stakeholders make informed decisions with regard to the sustainable utilization of one of our most pressured natural resources: fish stock. In order to do this I will be using an Individual Based Model (IBM) constructed in the Sustainable Fisheries Group here at the university, and forecasting various IPCC climate scenarios, combined with likely fishing intensity and selectivity.

Jessica Tengvall – PhD-student

I am a PhD student working on stock assessment and natural mortality. The aim of this PhD project is to untangle what happens when variability and directional change of natural mortality rates are ignored in stock assessment models (e.g. VPA, SAM, and XSAM). How does an incorrect natural mortality rate affect stock estimates, the maximum sustainable yield, and harvest control rules? This work will be able to improve stock assessment models and increase the effectiveness of sustainable fisheries management strategies.
