About the group
The main aim of the the group is to explain the fluctuations in population abundance, recruitment, growth and distribution of major fish populations. To do so we apply statistical analyses and modelling. Factors affecting these dynamics can be intrinsic, such as competition or cannibalism, and external, such as climate, fisheries and interaction with other species. Although the main focus is on fish our work also includes both lower and higher trophic levels (zooplankton, sea birds, marine mammals). Much of our work is based upon long, historical time series, which are indispensible for understanding long-term fluctuations. Several of our members are bio-economists and study economic aspects of fish harvesting. Other members use the latest genomic techniques to investigate patterns of local adaptation, and to investigate if fisheries affect the evolutionary potential of Atlantic cod, thus connecting us firmly with other groups at CEES.
