Johan Hjort symposium 2019

Challenging the scientific legacy of Johan Hjort: time for a new paradigm in marine research?

12–14 June 2019
Bergen, Norway

In 2019 we celebrate the 150-year anniversary of Johan Hjort (1869–1948), who introduced the fundamental theory for current fisheries science with his concepts of the roles played by strong and weak year classes in population structure and productivity. Since then a wide range of new methods and approaches have emerged to refine Hjort's theory, but today's knowledge of factors regulating stock dynamics, e.g. recruitment and migration dynamics, is still vague and thereby makes stock projections often highly uncertain. Moreover, the urge to broaden the standard routines in stock management to embrace today's holistic views, including ecosystem approaches to fisheries and on-going changes in the marine environment, implies an interdisciplinary co-operation. In order to move forward, the current situation asks for a profound insight in the past and present stage, and a dedicated search for new ideas and scientific framework.

To investigate the history, the present and to explore new directions in a free and creative atmosphere – in the spirit of Hjort – we invite marine researchers and historians of marine science to gather in this Bergen symposium, at the place where Hjort launched his paradigm-changing publication in 1914. 

We argue that by integrating data, information and perspectives, from a range of scientific fields, we will be able to reach a more advanced understanding of marine life as well as the practice of marine science in the past and present. Challenging the scientific legacy of Johan Hjort will be a truly interdisciplinary event, and bring historians together with marine and fisheries scientists.

The majority of the sessions will be set up as plenary sessions, and contain contributions from different bodies of knowledge.

Opening session: “Johan Hjort (1914): a Classic to Honour and Challenge"

This session will introduce the aims and ambitions for this symposium, but also to remember, examine and challenge the classics in marine research, with a particular focus on Hjort 1914.

Opening keynote speaker:

  • Professor Ray Hilborn, University of Washington, Seattle, USA

​Other keynote speakers:

  • Professor Akinori Takasuka, The University of Tokyo, Japan
  • Senior Research Scientist, Karen Evans, CSIRO, Hobart, Tasmania, Australia (tunas)
  • Director/Research Scientist, Robert L. Stephenson, DFO, St Andrews Biological Station, Canada (herring)
  • Science Leader/Principal Scientist Timothy M. Ward, SARDI, Henley Beach, Adelaide, Australia (“small pelagics”)
  • Principal Scientist Svein Sundby, IMR, Bergen, Norway (the recruitment enigma)
  • Killam Memorial Chair/Professor Jeffrey A. Hutchings, Dalhousie University, Canada
  • Researcher Dorothy Jane Dankel, University of Bergen, Norway
