The symposium

In 2019 we celebrate the 150­ year anniversary of Johan Hjort (1869–1948), who introduced the fundamental theory for 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, but today’s knowledge of factors such as recruitment, connectivity and migration dynamics is still vague and thereby makes stock projections uncertain. Moreover, the urge to broaden the standard routines in stock management to embrace today’s holistic views, including ecosystem approaches to fisheries and on­going changes in the marine environment, requires an interdisciplinary co­ operation. In order to move forward, the current situation asks for a profound shift in our approach, and a search for new ideas and a new scientific framework.

To investigate the history and 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 include plenary sessions and contain contributions from different fields.

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: Prof. Ray Hilborn, University of Washington, Seattle, USA.

Scientific legacy, theories and study species

In this session, we aim to explore theories, traditions, and long trends in fisheries investigations. Any fish stock in the world could be addressed. We have selected four commercially important categories of stocks to exemplify current and long trends in fisheries research and advice to be presented as keynotes by outstanding fisheries/marine scientists. Each keynote will be followed by complementary presentations (oral and poster), but with the flexibility to create stimulating and, perhaps controversial, discussions. This session will cover issues including vital rates (bioenergetics, natural mortality, growth, recruitment), intra­ and interspecific stock dynamics, and how to implement environmental stressors in the era of ocean observing and climate change. Synthesis work rather than studies on specific topics will be given priority, especially those addressing progress in science and “what now” issues.

On the shoulders of the giants of marine science

When should fisheries science revisit the past, and where should it search for new answers? This session examines and challenges the intellectual heritage and suggests ways forward. We want papers which search for a deeper insight in the present stage of scientific basis, and encourage the search for new ideas and scientific framework.

Keynote speaker: Killam Memorial Chair/Professor Jeffrey A. Hutchings, Dalhousie University, Halifax, Canada

The making of fisheries scientists

Here we turn to the fisheries scientists of today. This session explores how their cultural and disciplinary backgrounds shaped their decisions to go into this research field. Which factors influenced their choice of career and topics; how did their personal ambitions and creativity impact fisheries science? Did fisheries collapses, environmental crises or “role models” play a part?

Chair and moderator: Professor Jennifer Hubbard, Ryerson University, Toronto, Canada

Science and management, an uneasy pair?

This session examines how science influenced fisheries management decisions and fisheries policy, and the ways fisheries policy and management shaped fisheries/marine science. We welcome presentations (and papers) from marine scientists as well as managers emphasizing the value of past and on­going fisheries research in their daily operational decisions.

Keynote speaker: Researcher Dorothy Jane Dankel, University of Bergen, Bergen, Norway

When historians meet marine scientists

This is a special dialogue between historians and invited marine scientists. The goal is to investigate the past, present, and to explore potential new directions. We plan to send out questions beforehand. The session may include questions and comments from the public. Chair and moderator: Associate Professor Helen Rozwadowski, University of Connecticut, Groton, USA

Johan Hjort and the Bergen he saw

A photo exhibition of the life and work of Johan Hjort in Bergen will be part of the symposium. Research Professor Vera Schwach will introduce the exhibition. It will include a “marine science walk”: Across Bergen, in the footsteps of Johan Hjort. The aim is to visit important historical sites for marine research. In addition, we offer the opportunity to go on a short trip to the nearby fjord on IMR’s research vessel Johan Hjort.
