Short Course on Passage of Lamprey and Anguillid Eels

About the Course

This short course will review current aspects of upstream and downstream passage of North American lamprey species, including both west coast Pacific lamprey and Sea Lamprey, as well as generic aspects of passage of anguillid (freshwater) eels worldwide. Passage technologies for these nontraditional species are in development, and while success in passing these species in the past has been marginal, new advances in technologies and understanding of passage behaviors opens the door to implementing effective passage in the future. Specific topics will include: climbing ramp design and operation for lamprey and eels, passage behaviors, downstream protection via guidance and exclusion structures. Methods of selective passage for controlling invasive lamprey will also be reviewed.

Dr. Alex Haro ( is a Research Ecologist at the U.S. Geological Survey Leetown Science Center S.O. Conte Anadromous Fish Research Laboratory at Turners Falls, Massachusetts, USA and serves as a Principal Investigator and Section Leader of the Fish Passage Engineering Section.  His present work involves migratory fish behavior, design, engineering, and evaluation of fish passage structures, fish swimming performance, and ecology and management of American eels.  Dr. Haro provides extensive basic and applied research and advice to state, national, and international agencies, NGOs, and the private sector on fish passage technology and operations.  He is also an Adjunct Associate Professor at the University of Massachusetts Department of Natural Resources Conservation and serves as a major advisor for graduate students, as well as an instructor for courses in fisheries biology.

Dr. Mary Moser ( is a Fisheries Biologist with the National Marine Fisheries Service, Northwest Fisheries Science Center in Seattle, WA.  Using telemetry and PIT technologies, Dr. Moser has spent the last 15 years investigating behavior of adult Pacific lamprey and other anadromous species at both large hydropower dams and low-elevation irrigation diversion dams in the Columbia River drainage.  In the course of this research program, she has been directly involved in development of passage aids specifically designed for adult lamprey and in development of retrofits to existing fishways that provide passage for adult lamprey and/or protection of downstream migrant juveniles.  With her expertise in lamprey passage, Dr. Moser has been called upon to serve on both national and international expert panels and to assess fish passage at a variety of obstacles to lamprey.  Dr. Moser is an Honorary Professor at the University of Southampton, School of Civil Engineering and has served as an advisor on graduate student committees at the University of Guelph, University of New Brunswick, Oregon State University and the University of Idaho.
