Science Advisory Group Members

The Seafish Science Advisory Group (SAG) will provide high-quality, independent scientific challenge and support to ensure Seafish has access to the best possible scientific evidence, and where relevant, increase engagement with the scientific community.

Chair - Professor Michel J Kaiser
Michel Kaiser is the Professor of Marine Conservation Ecology at the School of Ocean Sciences, Bangor University, he is an independent Member of the Joint Nature Conservation Committee and the UK Marine Science Coordination Committee. Formerly he was a board member of Seafish from 2007 - 2015. He was a member of the Science Advisory Panel that oversaw the Marine Conservation Zones project in England. He co-convened the 6th World Fisheries Congress in 2012. After gaining his Ph.D. in 1991, he joined CEFAS to lead research on the effects of human activities (fishing and aquaculture) on the marine environment. He joined Bangor University in 1998 as a lecturer where he has expanded these interests to encompass social and economic consequences of different approaches of managing fishing activities. Michel was awarded a D.Sc. in 2003 in Marine Biology, and was awarded the Fisheries Society of the British Isles (FSBI) medal in 2004 for his contribution to fish and fisheries research. He was awarded a personal Chair in Marine Conservation Ecology in 2006.

His current research focuses on techniques to achieve sustainable use of the marine environment, with a particular emphasis on developing techniques to minimize ecological impacts of fisheries and aquaculture, and research to underpin the appropriate use of marine protected areas. The latter focuses on recovery and dispersal dynamics in seabed communities and integration of spatial social and economic valuation of marine biodiversity. His research group provides scientific advice to the Welsh Government and the Isle of Man Government.

Dr Grant D Stentiford FRC Path
Grant Stentiford is team leader for Pathology and Molecular Systematics at Cefas and Director of the European Union Reference Laboratory for Crustacean Diseases. His team works on diseases of fish and shellfish.

Dr Walter Crozier

Walter Crozier graduated in 1979 with an honours degree in Zoology from Queens University of Belfast (QUB) and subsequently received a Doctorate from QUB in 1983 in fish population genetics end ecology. He won a post-doctoral fellowship to study the biology of the angler fish Lophuis piscatorius in the Irish Sea, which he completed in 1985, then taking up a permanent post as a salmon biologist with the then Department of Agriculture for Northern Ireland. In 2005 Walter was appointed Head of the Fisheries and Aquatic Ecosystems Branch of DARD Science Service, which became the newly created Agri-food and Biosciences Institute(AFBI) in 2006. In this post he has been responsible for a science group delivering the core government fisheries science portfolio for Northern Ireland departments and thus has worked closely with policy customers and fishing  industry stakeholders. Throughout his career Walter has been an active researcher in fish population genetics, ecology and population dynamics and is the author of over 65 peer reviewed publications in these fields. He has served at senior level on a wide range of on national and international science bodies and has worked extensively in fisheries science advisory roles. His pastimes include photography and sailing.

Dr Bryce Stewart

Bryce is a marine ecologist and fisheries biologist whose work has ranged from temperate estuaries to tropical coral reefs and the deep-sea. The central thread in his research has been to gain an increased understanding of the factors regulating marine populations and communities so as to ensure their sustainable utilisation. His work on deep-sea fishes was among the first to demonstrate their extreme longevity, and on coral reefs he provided new evidence for mechanisms of community regulation of prey fish by predators. More recently his focus has been on how to improve the management of fisheries through the use of predictive recruitment models, marine protected areas and stock enhancement, particularly for scallops. Bryce has also been active in promoting the sale and consumption of sustainable seafood by working with everyone from government ministers to fishermen, restaurants and supermarket chains.

Dr Neil Auchterlonie

Neil is the Technical Director for the International Fishmeal and Fishoil Organisation (IFFO), the marine ingredients organisation (, based in London.  Neil has also worked as an independent aquaculture and fisheries consultant, previously holding technical roles in both government and industry with a strong emphasis on science management and technology transfer.  He holds a BSc (Biology) and PhD (Aquaculture) from the University of Stirling as well as an MSc (Applied Fish Biology) from Plymouth University.

Dr Simon Jennings

Simon Jennings is a Lead Adviser at Cefas. His current advisory role has been preceded by other senior roles as an advisor and research scientist, working nationally and internationally on marine environmental management and fisheries issues. Current external roles include membership of the Technical Advisory Board of the MSC. Simon also remains active as a research scientist, working with colleagues to further understanding of marine systems and their interactions with people and the environment. This understanding is being used to improve methods of monitoring, assessment and management.

Professor Mike Elliot

Professor. Mike Elliott, Institute of Estuarine and Coastal Studies (IECS), The University of Hull, UK Director of the Institute of Estuarine & Coastal Studies (IECS) ( and Professor of Estuarine and Coastal Sciences at the University of Hull, UK. Mike is a marine biologist with a wide experience and interests in marine and estuarine ecology, human impacts, marine and estuarine management and policy. His teaching, research, advisory and consultancy work has included studies of many ecological components and communities, as well as policy, governance and management of estuaries and coasts. Mike has published widely, co-authoring/co-editing 15 books and contributing to over 200 scientific publications. This includes co-authoring 'The Estuarine Ecosystem: ecology, threats and management' (with DS McLusky, OUP, 2004), 'Ecology of Marine Sediments: science to management' (with JS Gray, OUP, 2009), and 'Estuarine Ecohydrology: an introduction' (with E Wolanski, Elsevier, 2015) and as a volume editor and contributor to the Treatise on Estuarine & Coastal Science (Eds.-In-Chief - E Wolanski & DS McLusky, Elsevier). He has advised on many environmental matters for academia, industry, government and statutory bodies in Europe and elsewhere. Mike is a past-President of the international Estuarine & Coastal Sciences Association (ECSA) and is also one of the 4 Editors-in-Chief of the international journal Estuarine, Coastal & Shelf Science; he has Adjunct Professor and Research positions at Murdoch University (Perth), Klaipeda University (Lithuania), the University of Palermo (Italy), and the South African Institute for Aquatic Biodiversity, Grahamstown. From 2014 Appointed Independent Non-Executive member of the UK Marine Science Coordinating Committee and member of the Science Advisory Board of Marine Scotland. From 2014, member Society for Underwater Technology: International Salvage & Decommissioning Committee.

Professor Andrew Rowley

Andrew Rowley is a professor in the Department of Biosciences in Swansea University. He has published over 150 research papers in his career together with several books and review articles. His current interests are in marine aquaculture - especially disease control and biosecurity, and fisheries with particular reference to shellfish (lobsters, crabs and cockles).
