Villy Christensen is an ecosystem modeller with a background in fisheries science. He is known for his work as a project leader and core developer of Ecopath, an ecosystem modelling software system widely used in fisheries management. Ecopath was initially an initiative of the NOAA, but since primarily developed at the UBC Fisheries Centre of the University of British Columbia. In 2007, it was named as one of the ten biggest scientific breakthroughs in NOAA’s 200-year history. The citation states that Ecopath “revolutionized scientists’ ability worldwide to understand complex marine ecosystems".

Christensen did his Ph.D under Sven Erik Jørgensen at Copenhagen University. Jeffrey Polovina initiated the Ecopath approach in the early 1980s. Christensen, along with Daniel Pauly and others, has been involved in the subsequent development of Ecopath since 1990.
Christensen currently facilitates international workshops on Ecopath around the world. He is a professor at the UBC Fisheries Centre at the University of British Columbia, specialising in ecosystem modelling. His main project is with the Sea Around Us Project working on "database-driven ecosystem model construction", with the aim of using "global, spatial databases to parameterize, balance and fit ecosystem models". This work includes developing a dynamic exchange model of biomass over time in the Chesapeake Bay area, as well as how marine protected areas can be optimally positioned. He is also director of the Lenfest Ocean Futures Project, where a visualization system is being developed to support decision making in ecosystem-based fisheries management. This system combines Blender, a 3D-gaming engine, with Ecopath.
William Edwin "Bill" Ricker, (August 11, 1908 – September 8, 2001) is an important founder of fisheries science. He is best known for the Ricker model, which he developed in his studies of stock and recruitment in fisheries. The model can be used to predict the number of fish that will be present in a fishery. He also had an international standing as an entomologist and a scientific editor. He published 296 papers and books, 238 translations, and 148 scientific or literary manuscripts.Boris Worm
Boris Worm is a marine ecologist and Killam Research Professor at Dalhousie University; Halifax, Canada. His research program focuses on changes in marine biodiversity, and the effects of fisheries, climate change, and other human impacts on global ocean ecosystems. He is a frequent commentator on marine environmental issues in the media, and has won numerous awards for his scientific work and public outreach.
He received both a M.Sc. (1996) and Ph.D. (2000) from the University of Kiel, Germany and worked as a postdoctoral fellow with the late Ransom A. Myers at Dalhousie. He joined the faculty at the Biology Department, Dalhousie University in 2004. Dr. Worm and his students have published over 100 peer-reviewed scientific articles, several of which have become citation classics. Dr. Worm was identified as a Highly Cited Researcher by Thompson-Reuters in 2014.
Dr. Worm has contributed to several well-known ocean documentaries, including Sharkwater (2007), End of the Line (2007), Revolution (2012), and Racing Extinction (2015). Since 2010, Dr. Worm has produced a regular column for CBC Radio, focusing on ocean science and policy. Since 2013 he is the Scientific director of Ocean School, a collaborative ocean education initiative between Dalhousie University and the National Film Board of Canada.Bruno Hofer

Callum Michael Roberts is a marine conservation biologist, oceanographer, author, research scholar at the University of York, England.Ecopath
Ecopath with Ecosim (EwE) is a free ecosystem modelling software suite, initially started at NOAA by Jeffrey Polovina, but has since primarily been developed at the UBC Fisheries Centre of the University of British Columbia. In 2007, it was named as one of the ten biggest scientific breakthroughs in NOAA's 200-year history. The NOAA citation states that Ecopath "revolutionized scientists' ability worldwide to understand complex marine ecosystems". Behind this lie more than two decades of development work in association with Villy Christensen, Carl Walters, Daniel Pauly, and other fisheries scientists, followed with the provision of user support, training and co-development collaborations. Per January 2012 there are 6000+ registered users in 150+ countries.FishBase
FishBase is a global species database of fish species (specifically finfish). It is the largest and most extensively accessed online database on adult finfish on the web. Over time it has "evolved into a dynamic and versatile ecological tool" that is widely cited in scholarly publications.FishBase provides comprehensive species data, including information on taxonomy, geographical distribution, biometrics and morphology, behaviour and habitats, ecology and population dynamics as well as reproductive, metabolic and genetic data. There is access to tools such as trophic pyramids, identification keys, biogeographical modelling and fishery statistics and there are direct species level links to information in other databases such as LarvalBase, GenBank, the IUCN Red List and the Catalog of Fishes.As of November 2018, FishBase included descriptions of 34,000 species and subspecies, 323,200 common names in almost 300 languages, 58,900 pictures, and references to 55,300 works in the scientific literature. The site has about 700,000 unique visitors per month.Fred M. Utter
Fred Utter is an affiliate professor in the School of Oceanography at the University of Washington. He was recognized by NOAA in 2006 as one of their 26 history makers over the preceding 200 years, and characterised as the founding father of fishery genetics. In 1959 he began work in the ancestor laboratory of the NOAA Northwest Fisheries Science Center fishery genetics laboratory, of which he became the head in 1969. He led the genetics group until he retired from NOAA in 1988. During retirement, he has remained active in the field, acting as editor of the North American Journal of Fisheries Management and Transactions of the American Fisheries Society, as well as being a member of the Interior Columbia River Technical Recovery Team. He has authored over 100 scientific publications, and co-edited the book Population Genetics and Fishery Management.Frederikshavn Municipality

SeaLifeBase is a global online database of information about marine life. It aims to provide key information on the taxonomy, distribution and ecology of all marine species in the world apart from finfish. SeaLifeBase is in partnership with the WorldFish Center in Malaysia and the UBC Fisheries Centre at the University of British Columbia. Daniel Pauly is the principal investigator and it is coordinated by Maria Lourdes D. Palomares. As of October 2016, it included descriptions of 74,000 species, 47,700 common names, 12,400 pictures, and references to 31,700 works in the scientific literature. SeaLifeBase complements FishBase, which provides parallel information for finfish.The Old Mill on Mols

The UBC Institute for the Oceans and Fisheries (IOF) is a research unit at the University of British Columbia (UBC) that was formed in 2015 by incorporating members from the former UBC Fisheries Centre (est. 1991, dis. 2015), as well as a subset of researchers that are conducting marine related research at UBC. Members of the IOF are drawn primarily from the Departments of Earth, Ocean and Atmospheric Sciences, Zoology and Botany. The UBC Institute for the Oceans and Fisheries brings together a community of Canadian and international experts in ocean and freshwater species, systems, economics, and issues to provide new insights into how global marine systems function, and the impacts of human activity on those systems. It is working towards a world in which the oceans are healthy and their resources are used sustainably and equitably. IOF is located at The University of British Columbia, and promotes multidisciplinary study of aquatic ecosystems and broad-based collaboration with researchers, educators, maritime communities, government, NGOs, and other partners.Uwe Kils
