Interviews with previous students

Johanna Myrseth

Johanna graduated in 2009 with a Masters thesis in Fisheries management: Managing marine fish populations under uncertain estimates. What are the benefits of stock information?

She became interested in theoretical ecology though a course in aquatic ecology with prof. Øyvind Fiksen where he introduced her to theoretical modeling.

- I was very fascinated by how one could explain/simulate nature with mathematical equations, and decided that I wanted to do my thesis using this type of research method.

In her thesis in fisheries management, Johanne studied how uncertainty in fish population estimates affects the annual harvest of the population as well as fluctuations in the population's biomass. The results have been presented at international conferences and published in a scientific journal:

Myrseth J, Enberg K, Heino M, Fiksen Ø. 2011.
Do accurate stock estimates increase harvest and reduce variability in fisheries yield?
Natural Resource Modelling. 24: 222-241. [ pdf ]

Since her graduation Johanna has worked in several fields, including The Norwegian Trekking Association and Norsk Gjenvinning . Currently, she has just started her PhD education at the Institute of Marine Research , with Øyvind Fiksen as her co-supervisor.

Knut Wiik Vollset

Knut finished his Masters degree in 2006, and PhD in 2010.

He was affiliated with the Theoretical Ecology Group through prof. Øyvind Fiksen, who was his co-supervisor during both Masters and PhD degrees.

- I worked primarily with growth and survival during early life stages of two populations of Atlantic cod (Gadus morhua) in large outdoor mesocosms. The results contradict some of the earlier findings of population differences.

After finishing his PhD in December 2010, Knut was hired by Uni Environment, to work with wild salmon ecology and the interaction between wild fish and farming and river regulation. More specifically he belongs to the sub-group The Laboratory for Fresh water ecology and inland fisheries.

- Currently, I work as a Senior Researcher and do both field work and publish articles on anthropogenic effects on wild Atlantic salmon and trout .

Knut has published several articles from both his Masters and PhD work. You can find more information about his work here.

Kristian Andvord

Kristian graduated in 2008 with a Master thesis in Fisheries management: Activitiy and space-use in European lobsters from ultrasonic tracking in a marine protected area .

His master thesis focused on the behavioral ecology of the European lobster, and was part of a larger research project which investigated whether establishing marine protected areas is a suitable means to rebuild the depleted lobster stocks. He investigated lobster movement and activity patterns by tracking lobsters marked with radio acoustic tags.

- I chose the Theoretical Ecology group because their competence was relevant for the type of problems I wanted to investigate in my Master thesis. I also had close collaboration with the Institute of Marine Research, in Flødevigen, Arendal, where I did my fieldwork .

Shortly after graduation Kristian started working as an adviser for the Norwegian Ministry of Fisheries and Coastal Affairs. The Ministry is responsible for the management of the fisheries and aquaculture industries in Norway.

- My work is primarily concerned with developing and implementing environmental policies for the fisheries and aquaculture sectors.
