Johanna Bjånes Marcussen

PhD Research Fellow

My research focuses on the study of population dynamics in marine shellfish, including lobsters, red king crab, and brown crab, and their assessment to provide fisheries advice. My current work involves the assessment of data-limited shellfish stocks, particularly brown crab, Nephrops, and European lobster. Furthermore, I am engaged in projects to explore the impact of unaccounted fishing mortality, such as recreational fishing, on stock estimates and uncertainty. This research contributes to the understanding of marine ecosystem dynamics and the sustainable management of shellfish fisheries.
