ConEvolHer officially kicked off 13th-14th April in Bergen!

The entire project group including the international participants Bruno Ernande (IFREMER) and Marc Mangel (UCSC) and a special guest Shaun Killen (University of Glasgow) gathered in Bergen for a two-day meeting to present current research and discuss ongoing and upcoming project plans.

 All participants contributed with talks on project-related topics, in particular on background information on the project, specific project tasks, Norwegian spring-spawning herring and fishing-induced evolution, but also density dependence and stock assessment. Additionally, PhD-students Gabriella Ljungström  and Tom Langbehn introduced their research plans. Both are part of the MARmaED project, a Marie Sklodowska-Curie European Training Network under Horizon 2020, where Institute of Marine Research is a partner. Within a productive and stimulating atmosphere, the aggregated expertise was able to resolve previous challenges, outline the next steps, and devise ideas for future research.

List of talks by the participants:

  • Katja Enberg: Introduction to the project
  • Marion Claireaux 1) Bioenergetics-statistical modelling 2) Modelling effects of behaviour-selective fishing
  • Fabian Zimmermann: Density regulation and recruitment variability in North Atlantic stocks
  • Aril Slotte: Norwegian spring spawning herring - an overview of the stock and data available
  • Arild Folkvord: Strong herring year classes after 1904 - how have they affected growth of subsequent year classes?
  • Marc Mangel: Density dependence, the theory of harvesting, and the practice of stock assessment: A perspective on steepness and its implications
  • Mikko Heino: FiE overview and new challenges
  • Bruno Ernande: Estimation of energy allocation parameters and age and size at maturation using otolith back-calculated growth curves
  • Anders Opdal: A novel approach to disentangling demographic and genetic effects of harvesting
  • Christian Jørgensen: Fishing-induced evolution causes higher natural mortality
  • Shaun Killen: The role of physiology in fisheries-induced evolution
