Governance and Program Design Indicators

Suzanne Iudicello, J.D. (Principal, Iudicello Consulting) earned her J.D. from the National Law Center at George Washington University. She consults on fishery management policy to state and federal government agencies, foundations, fishing associations, and conservation organizations. She has conducted reviews of the New England groundfish buyout, the Cape Cod Hook and Line Sector Program, and the Pacific coast groundfish draft environmental impact statement and port socioeconomic impact statement. She evaluated the potential applicability of rights-based systems to community-based fishery management in Port Orford, Oregon. She served on the indicator design committee for the State of the Nation’s Ecosystems report produced by the Heinz Center for Science, Economics and the Environment.

Ecological Indicators

Tim EssingtonTim Essington, Ph.D. (Associate Professor, University of Washington) holds a M.S. in fisheries and wildlife conservation from the University of Minnesota and a Ph.D. in zoology from the University of Wisconsin-Madison. He is a marine fisheries ecologist whose research focuses on interactions between human activities and marine food webs and on the effectiveness of fishery management approaches. He works in ecosystems ranging from estuaries to the open ocean, and he uses a wide variety of quantitative techniques to evaluate how ecological systems respond to fishing. He has published numerous peer-reviewed scientific articles in journals such as Fisheries, Fish and Fisheries, Limnology and Oceanography, Ecological Applications, and Proceedings of the National Academy of Sciences.

Trevor Branch, Ph.D. (Assistant Professor, University of Washington) holds a Ph.D. in aquatic and fishery sciences from the University of Washington. He is a quantitative fisheries scientist who has published multiple papers detailing the effects of catch-share fisheries. In his research, he has compared the U.S. west coast fishery with the catch share system in place in British Columbia, examining discards, revenues, fleet sizes, and changes in fishing behavior, in addition to reviewing the ecological effects of catch share programs. He has published numerous peer-reviewed scientific articles in journals including Science, Nature, Trends in Ecology and Evolution, Proceedings of the National Academy of Sciences, and Fish and Fisheries.

Peter Kuriyama, B.A. (Ph.D. Student, University of Washington) holds a B.A. in biology from the College of Creative Studies at the University of California, Santa Barbara. His dissertation research focuses on the effects of catch shares in North America and on stock assessment methodology. He has published scientific papers in Fisheries Research and Marine Policy and contributed to the assessment of petrale sole for the Pacific Fishery Management Council.

Economic and Social Indicators

Marcus HartleyMarcus Hartley, M.S. (Vice President & Senior Economist, Northern Economics) holds a M.S. in agricultural and resource economics from Oregon State University and has more than twenty years of experience in fisheries economics. He has completed fisheries-related projects for the Pacific Fishery Management Council, Pacific States Marine Fisheries Commission, NOAA Fisheries Service regional offices (Alaska, Pacific Northwest, Western Pacific, Gulf of Mexico, and Northeast), and other federal, state, and local agencies and non-government organizations. Previously, he was senior economist at the North Pacific Fishery Management Council, and he has worked on nearly every allocation, access, and catch share issue for Alaska’s groundfish, halibut, crab, and salmon fisheries since 1989.

Donald Schug, Ph.D. (Socioeconomic Analyst, Northern Economics) has professional experience in a wide range of fisheries-related research and applied work in the United States and abroad. As a consultant with NEI, Dr. Schug has conducted several economic and social analyses of fisheries that are currently managed under catch share programs or for which such programs are proposed. Particularly relevant studies to which he contributed include the development of an analytical approach for an environmental review of the Pacific Coast groundfish trawl fishery rationalization program; a summary of the economic regulatory analysis of the fishery management plan amendments creating the Pacific Coast groundfish trawl fishery rationalization program; an analysis of cooperative arrangements to manage the financial risk associated with constraining species catch in the Pacific Coast groundfish trawl fishery following rationalization program implementation; and a post-implementation evaluation of the BSAI crab rationalization program.

Michael Downs, Ph.D. (Senior Social Scientist, Northern Economics) has 29 years experience on complex projects throughout the United States, including specialized fisheries experience in social impact assessment (SIA), socioeconomics, environmental justice, subsistence, and traditional-use issues.
