Yong Chen is a fisheries scientist and faculty member at the University of Maine’s School of Marine Sciences. His research focuses on quantitative fisheries ecology, stock assessment, and management of fisheries resources. Much of Chen’s work is interdisciplinary and involves fisheries biology, ecology, mathematical and statistical modeling, management policy, and computer simulations. His research interests include evaluating fish life history and environmental impacts, designing fisheries-dependent and fisheries-independent survey programs, and conducting risk analysis of alternative management strategies.

Chen co-led a project funded by the Mitchell Center. His team built relationships with lobstermen working in the Gulf of Maine in order to address the problem of bycatch. They worked closely with lobstermen to assess the ecological, social, and economic impacts of bycatch in the region.

In addition to working at the University of Maine, Chen is a visiting professor at Shanghai Ocean University in China. He is currently the editor of the Canadian Journal of Fisheries and Aquatic Sciences. Chen was recognized in 2008 with a University of Maine Graduate Mentor Award. Since 2009, he has coordinated both the UMaine Marine Policy and UMaine Dual Master Degree in Natural and Social Sciences programs. Chen is currently a member of the New England Fisheries Management Council Scientific and Statistical (SSC) Committee.

Chen’s research has been funded by the Canadian Natural Science and Engineering Research Council, NOAA’s National Marine Fisheries Service, both the National and Maine Sea Grant programs, the Atlantic States Marine Fisheries Commission, the National Science Foundation, the Maine Department of Marine Resources, and the Maine NSF EPSCoR SSI program, among others.

Chen has been published in peer-reviewed journals including the Canadian Journal of Fisheries and Aquatic Sciences, ICES Journal of Marine Science, Fisheries Research, Aquatic Ecology, Journal of Fish Biology, Fishery Bulletin, Chinese Journal of Oceanology and Limnology, Marine Biology, Marine Ecological Progress Series, Freshwater and Marine Research, and Ecology and Society.
