This Year's Awardees

Daniel Pauly

Beverton Medal Awardee

We are delighted to announce that the Awardee of the 2021 Beverton Medal is Professor Daniel Pauly. The Beverton Medal is awarded in recognition of ground-breaking research and lifelong contribution to the study of fish and fisheries science.

Daniel Pauly moved to the Fisheries Centre of the University of British Columbia in Vancouver as Professor in 1994 and was its Director from 2003 to 2008. As an extension to his work for FishBase and SeaLifeBase, which provide marine biodiversity information globally, he created the Sea Around Us project, which provides information on global marine fisheries since 1950. He is currently University Killam Professor at the University of British Columbia. His achievements are characterised by an original, outspoken and pragmatic approach that earned him a lot of supporters, and some critics. He has been at the forefront of the development of models and tools used worldwide for the analysis of aquatic ecosystems and fisheries. Daniel Pauly has authored or co-authored over 1000 scientific articles, book chapters and shorter contributions, and authored, or (co-)edited about 30 books and reports. Among his 15 most cited publications are five in the top journal Science and Nature.

He was one of the first to point out that fishing dramatically affects fish stocks. He identified global trends in fishing and developed the concept of fishing down the food web. The idea of shifting baselines, or the floating frame of reference of young researchers for what an original fish stock actually represents, also belongs to him.

He is currently the most influential scientist in the field of fisheries biology. He has received 37 prizes and awards since 2000. Daniel was also knighted as Chevalier de la Légion d’Honneur (2017) by the French government.

Daniel Pauly is a passionate scientist who enters into discussion with society. His mission is to secure the oceans so that future generations, rich and poor, can continue to catch and eat fish. The world citizenship and sense of justice of Daniel is undeniably linked to his turbulent youth. He was born in Paris in 1946 but grew up in Switzerland in unenviable circumstances. At the age of sixteen he left for Germany to continue his secondary studies.

Thanks to a scholarship he was able to study biology at Christian Albrecht University in Kiel. During his university studies he carried out fish research in Ghana and Indonesia. After obtaining his doctorate in Fisheries Science at the University of Kiel in 1979, he joined the International Center for Living Aquatic Resources Management (ICLARM) in Manila (Philippines), the current WorldFish Center. Time and again, he was confronted with the limitations of fisheries research and the problems of fisheries in developing countries. A major achievement is his 'Pauly equation', a simple equation for calculating natural fish mortality, which one of his most cited publications. This gave rise to his idea of collating and disseminating data on the economically most important fish in a database, so that they would also be available to scientists in developing countries. This eventually led, in collaboration with computer specialist Rainer Froese and through a strong team of partners and staff, to the development of FishBase, the world's largest online fish encyclopaedia.

Ian Winfield

Le Cren Medal Awardee

We are delighted to announce that the Awardee of the 2021 Le Cren Medal is Ian Winfield.  The Le Cren medal is awarded to one or more individuals who have made a lifelong contribution to all aspects of the study of fish biology and/or fisheries science, with a focus on conservation, training or public understanding of the discipline.

Ian Winfield is a name known to many people involved in fish and fisheries science within the UK, and globally. Not only for his impressive research output, but through his long-standing relationship with the FSBI – where he is perhaps one of the few to have occupied several Officer roles within the Society, including Honorary Treasurer (1997-2005), Honorary Secretary (2017-2021) and President (2011-2015).

In a professional career which has spanned 40 years Ian has authored over 200 scientific papers in peer-reviewed journals on topics that range from behavioural ecology, genetics, population biology and invasive species to climate change. When added to the over 350 contracted science reports and 43 popular scientific articles that he has published, he has made a significant, and long-term, contribution to our field. Not only in terms of publishing hard science, but also its application to real world issues, and in making it accessible to a wider general audience.

A native of Hull, Ian started his scientific career at Bangor University, where he came under the influence of Tony Pitcher, a well-established fish biologist who mentored him during this early stage in his scientific training. He then moved back to England to join a vibrant research group at the University of East Anglia led by Colin Townsend. It was during his time as a PhD student, working on Alderfen Broad, that Ian’s interest in the ways in which cyprinid-dominated communities can influence freshwater ecosystems really took off. This eventually led to the publication of his own magnum opus on the systematics, biology and exploitation of cyprinid fishes (co-edited with the late Joe Nelson of University of Alberta, Canada). It continues to be widely cited.

Following completion of his PhD in 1983, he moved to a research fellowship the University of Lund in Sweden and then to a lectureship at the University of Ulster’s (UU) Limnology Laboratory on the shores of Lough Neagh in Northern Ireland. Ian made an immediate impact at UU and was instrumental in developing long-term monitoring strategies for a range of freshwater species. But it was his exposure to Coregonus autumnalis that sparked an interest in coregonids that would dominate much of his future scientific career. In 1990 he made the move back across the Irish Sea to lead freshwater fish work at the Institute of Freshwater Ecology (now UK Centre for Ecology & Hydrology (UKCEH)). There, in addition to inheriting the role of maintaining long-term datasets on pike, perch and Arctic charr in Windermere, he was also located in the epicentre of the UK’s meagre, but important, collection of coregonid populations. He rapidly became an internationally recognised expert on the monitoring and management of rare European whitefish and vendace populations. His work in this area is well recognised.

Ian’s enthusiasm is natural and contagious, and the breadth of his interests and contributions are exemplified further by his quick recognition and contribution to state-of-the-art approaches in fish and fisheries science, such as his early publications on freshwater applications of hydroacoustics and environmental DNA. Always supportive of students and ECRs, Ian is, in every way, a model scientist. Although retired from full-time employment with UKCEH he remains active in the fish scene through his duties as Honorary Secretary to the FSBI, and continued involvement in research and student supervision.

Christos Ioannou

FSBI Medal Awardee

We are delighted to announce that the Awardee of the 2021 FSBI medal is Dr Christos Ioannou. The FSBI medal is awarded to an early career scientist who is deemed to have made exceptional advances in the study of fish biology and/or fisheries science in recognition of their achievements.

Christos Ioannou completed his PhD in 2008, and is currently Associate Professor in Behavioural Ecology, School of Biological Sciences, University of Bristol, where he held previously a lectureship and NERC (UK) fellowship. Christos has established himself as an influential fish biologist and is especially noted for ground-breaking contributions in the fields of predator-prey relationships and collective decision-making. His contributions are exemplified by a strong publication record (46 journal papers which include many first- and last-authorships in Science, PNAS, Nature Communications and Science Advances with 3710 career citations and an h-index of 27 to date). He is recognised as a gifted experimental biologist, characterised by an unusual talent to work with mathematicians and computer scientists.

One of his biggest achievements is the development of a new approach to the study of fish behaviour which involves interactions between real predators and virtual prey. This approach allows Christos to investigate how predators select for behavioural traits in their virtual prey over multiple generations thereby providing unparalleled insights into evolutionary processes. Major first-author papers in, for example, Science (2012) and PNAS (2019) have resulted from this work and have been highly influential. An additional noteworthy research domain is Christos’ work on collective decision-making behaviour. His first major contribution in this area was a Science paper in 2011 which showed that a minority of fish with a strong directional preference can dictate group choice, but the presence of uninformed individuals spontaneously inhibits this process, returning control to the numerical majority. He followed this paper with another study on leadership which showed that effective leadership required informed fish to appropriately balance goal-oriented and socially oriented behaviour (American Naturalist 2015). More recent work has focused on the role of the individual in collective decisions, also highlighting the importance of population differences in this context. In this work he used his background in collective behaviour and connected it to aspects of animal personality and information use (Nature Communications 2020).

Most recently, he has broadened his research to take an applied perspective to understand how the predatory and social behaviour of fish interacts with changing habitats driven by anthropogenic activity. This work so far has explored the effects of invasive species, turbidity and anthropogenic noise on fish behaviour. Christos has become a major presence at many international conferences and he successfully fosters new talent in his rapidly expanding research group.

Presentation of the Medals

The Beverton, FSBI and Le Cren medals are presented to the successful nominees at FSBI's annual International Symposium which is usually held in July of each year, or if this is not possible then at a place and time mutually agreed between the Society and the recipient. In addition, all three medallists are invited to give a short presentation on their research during the symposium.
