Kenneth Tiffan

Snake River fall Chinook salmon were listed as “threatened” under the ESA in 1992. My entire career has focused conducting applied research to provide information that would increase our understanding of this unique stock and facilitate recovery efforts.  The work of myself and colleagues from other agencies have produced most of the contemporary information on Snake River fall Chinook salmon.

Biography

Education:

M.S. 1992. Fishery Biology, Colorado State University, Fort Collins, CO

B.S. 1987. Fishery Biology, Colorado State University, Fort Collins, CO

 

Research Interests:

The main focus of my work is understanding Snake River fall Chinook salmon life history and ecology to support recovery of this listed stock.  Over the years research topics have included migratory behavior, habitat use and quantification, physiology, and feeding ecology of juvenile fish in the Snake and Columbia rivers.  Other research areas have included understanding the effects of elevated flows on chum salmon spawning behavior, and investigating recent food web changes to lower Snake River reservoirs.
