Study Committee


Ray Hilborn, Professor Hilborn was co-leader of the original NCEAS working group with Boris Worm on which this study is modeled.  He has done considerable research on the impacts of fishing from that project and many others.  He currently has 3 post-docs and several students working on analysis and expansion of the database on fisheries status and trends.

Simon Jennings Simon Jennings has led several research projects to quantify the environmental effects of trawling and to assess how the dynamics of fishing fleets affect their interactions with seabed habitat. Through the Centre for Environment, Fisheries and Aquaculture Science he provides impartial scientific advice on fishing-environment interactions to a range of national and international bodies.

Michel Kaiser, Professor Kaiser has 20 years’ experience working on impacts of fishing gear on seabed habitats and has published over 145 papers. He currently has 2 post-docs and 6 PhD students. He is the Deputy chair of the UK Seafish Industry Authority that interfaces between industry, science and policy makers and is therefore well placed to disseminate outputs from this project to global industry leaders.

Adriaan Rijnsdorp Adriaan Rijnsdorp studied population biology of flatfish and the ecosystem impact of beamtrawl fisheries and published over 100 papers. He is coordinating a pan-European research project on Integrating the Role of Marine Benthic Ecosystems in Fisheries Management (BENTHIS) and supervising two related PhD-projects.

Roland Pitcher Roland Pitcher, Principal Research Scientist CSIRO, has >30 years experience working on fisheries and marine ecology, including a series of large-scale projects on the impacts of trawling in NE Australian regions. These comprised experiments on direct effects, recovery dynamics, fishing effort patterns, regional-scale biodiversity distribution surveys and impact analyses, dynamic modelling of trawl impacts and management strategies, and quantitative sustainability risk assessments for >1000 bycatch species. Outputs have been adopted into management outcomes, and approaches are now being applied in SE and NW Australia.

Bob McConnaughey Bob McConnaughey is a Research Fishery Biologist with NOAA Fisheries where he leads a multi-disciplinary research team studying offshore habitats in the eastern Bering Sea. Several large-scale field investigations of bottom-trawl effects have been designed and executed, involving close interaction with Native Alaskan communities and the commercial fishing industry. A research plan for new studies in a previously unfished area of the arctic was recently prepared in response to regional managers’ concerns about potential impacts if commercial trawling is authorized. He is particularly interested in the relationship between levels of natural disturbance and the overall sensitivity of benthic communities to bottom trawling.

Jeremy Collie Jeremy Collie is Professor of Oceanography at the Graduate School of Oceanography (GSO), University of Rhode Island. He studied Biology at the University of York, England and was awarded his doctorate in Oceanography from the Massachusetts Institute of Technology / Woods Hole Oceanographic Institution. He worked in British Columbia and Alaska before moving to Rhode Island in 1993. Collie is a quantitative ecologist who specializes in fish population dynamics. He also studies the impacts of disturbance on benthic communities, predator-prey interactions, stock assessment and fisheries management. Since 1998, he has supervised the GSO Fish Trawl.

Jan Hiddink Jan Geert Hiddink studies the impacts of bottom trawl fisheries and climate change on benthic ecosystems. His research combines ecological modelling, ship-based research and the analyses of long-term data sets to assess and predict the effect of disturbances on the functioning of marine ecosystems. He has published 48 papers and is supervising six PhD-students. Web Page

Ana Parma Ana Parma is a fisheries scientist with the Argentine National Council for Science and Technology, working at a research center in Patagonia. Originally trained in fisheries stock assessment and modeling at the University of Washington, she worked at the International Pacific Halibut Commission for 10 years before returning to Argentina in 2000, where she became more involved with the assessment and management of coastal fisheries. She is now coordinating a project focused on the evaluation of impacts of shrimp trawling in a region of high conservation significance in the Patagonian coast.

Kathryn Hughes Kath’s research focus considers characterising ecological and anthropogenic drivers of the distributions of fish populations, and attempts to disentangle one from the other. Of particular focus is the use of varying spatial scales to elucidate sound ecological patterns in populations of pelagic and groundfish distributions and relative abundance and potential mechanisms of change in time and space in the marine environment. Kath is a member of several ICES working and advisory groups and has recently completed her PhD since when she has joined the Trawl Committee Team as a Postdoctoral Researcher.

Petri has a Ph.D in fisheries science and aquatic ecology from the University of Helsinki and 30 years of professional experience in fisheries research and development. His special field of expertise is the development and practical implementation of technical management measures and the evaluation of ecological and socio-economic impacts of these measures. In 1996-2009 he was the Director of the Fisheries Research at the Finnish Game and Fisheries Research Institute. Since 2009 has worked at FAO Fisheries and Aquaculture Department’s Fishing Technology and Operation Service (FIRO). He has 80 scientific publications and book chapters, mainly on various fields of technical fisheries management measures. 

Ricky has a Doctor of Biology from National University of Comahue in Argentina studying the meta population dynamics and management of scallops. He is a post-doctoral fellow at the University of Washington.


Tessa has a Ph.D. in biology from the University of Queensland. A key component of her doctorate research was modelling (species distribution modelling, remote sensing, predictive modelling), particularly for addressing the limitations of data availability and working across broad spatial scales. She is a post-doctoral fellow at the CSIRO lab in Brisbane.
