John Beeman

I began working as a fishery biologist with the U.S. Department of the Interior in the 1980s, retired in 2016, and continue my affiliation with Interior under their Emeritus program.  My experience revolves around migratory riverine fishes and their interactions with hydropower systems.

Biography

Education:

B.S. 1981. Biology, St. John’s University, Collegeville, MN

M.S. 1984. Biology, University of South Dakota, Vermillion, SD

 

Research Interests:

I am interested in any topic related to fish migration and survival, and most often studied fish movements using some form of telemetry.  My colleagues and I commonly evaluated fish passage systems and estimated survival of juvenile salmonids using a variety of probability-based methods such as Cormack-Jolly-Seber models.   Most of our work was associated with migrations of riverine fishes at low- and high-head dams in the western USA, particularly in the Columbia River and nearby systems in the Pacific Northwest.  We usually used radio or acoustic telemetry to track fish movements and their presence/absence to inform management decisions about the effectiveness of fish passage systems and to diagnose system deficiencies.  That work enabled me to provide technical assistance to several international groups beginning in 2012, primarily to those living and working near the Mekong River in Southeast Asia.
