3 Welcome to Newport, OR and the 19th Western Groundfish Conference Welcome to the central Oregon coast and the 2016 Western Groundfish Conference. The WGC has always provided a unique opportunity to review current research and management concerning West Coast groundfish resources; including fisheries, management, stock assessment, ecology, habitat, and new technologies. This year s conference will include contributed oral presentations and a poster session, plus four evening events planned to allow conference participants to network and discuss ongoing projects. The conference banquet will include a keynote address by Dr. Ellen Pikitch, formerly on the faculty at Oregon State University, Department of Fisheries and Wildlife in Newport, Oregon and now executive director of the Institute for Ocean Conservation Science and a professor at the School of Marine and Atmospheric Sciences at Stony Brook University. The informal conference atmosphere is intended to encourage dialogue among researchers, managers, government agencies, conservation groups, and industry. We hope you enjoy your time in Newport, the conference, and the opportunity to interact with other groundfish aficionados. Sincerely, Lynn Mattes (ODFW) and David Sampson (OSU) and the 19th WGC Organizing Committee The 2016 Organizing Committee: IPHC Claude Dykstra, Ed Henry, Kirsten MacTavish NMFS Keith Bosley, Tom Hurst, Waldo Wakefield The Nature Conservancy Gway Kirchner ODFW Ashley Knight, Lynn Mattes, Ali Whitman OSU Faculty Scarlett Arbuckle, Scott Heppell, David Sampson OSU Students Linsey Arnold, Noelle Yochum

Pikitch is a professor at the School of Marine and Atmospheric Sciences at Stony Brook University and is the executive director of the Institute for Ocean Conservation Science. Dr. Pikitch has spearheaded the first scientific consensus on ecosystem-based fishery management and chaired the Lenfest Forage Fish Task Force. Her research efforts focus on vulnerable and ecologically important marine species, including pelagic sharks and both Atlantic and beluga sturgeon. Her work has informed policy decisions such as the listings under the U.S. Endangered Species Act, passage of the U.S. Shark Finning Prohibition Act, and more precautionary forage fisheries management. Dr. Pikitch received a Ph.D. in Zoology from Indiana University and M.A. and B.S. degrees in Mathematics from the City College of New York.
