Background
Lyle Gilbreath first joined the NWFSC's Coastal Zone and Estuarine Studies Division--which later became the Fish Ecology Division--in 1971. His projects have included: coded-wire-tag marking of juvenile salmonids for transportation and homing studies; sampling returning adult salmonids; evaluating juvenile passage at hydroelectric projects, including fish guidance efficiency, orifice passage efficiency, bypass system passage survival, and effects of bypass system passage on fish condition and physiology, and investigating the limnological characteristics of John Day Reservoir. Lyle graduated from Washington State University with a B.S. in zoology.
Current Research
Lyle's current research is designed to investigate differential mortality rates for juvenile chinook salmon passing through the Snake/Columbia river hydropower system. His responsibilities include planning and justifying research protocols, operating and maintaining a 25,000-gallon recirculating seawater system at Bonneville Dam, acquiring and rearing test fish in the seawater system and analyzing and presenting results of his studies. He also recruits, trains, schedules and supervises a staff of eight personnel who monitor the seawater system and care for the research fish on a 24-hour, seven-day schedule. Lyle coordinates research activities with the U.S. Army Corps of Engineers, other state and federal fisheries agencies, and other NWFSC divisions.
