Ryan Koch

Ryan Koch (pronounced, "Cook") has been working for the USFWS: Columbia River Fisheries Program Office since November of 2005. He currently is a biologist on the Water Management and Evaluation team. Specifically, he works on the bull trout crew, which conducts monitoring and research studies utilizing all aspects of PIT and radio telemetry technology to investigate movement patterns, spatial and temporal distribution and identify spawning and rearing habitat suitability criteria for ESA listed bull trout in the Walla Walla River Basin.

Prior to working at CRFPO, Ryan was employed by USGS: Columbia River Research Laboratory in Cook, WA. He worked on the main stem Columbia and Snake Rivers for over 3 years, focusing on the effects of hydroelectric projects on juvenile and adult salmonid behavior using radio telemetry and hydro acoustics. In addition, he also worked on a pre-restoration project that studied the use of habitat by juvenile salmonids at Crims Island (Columbia River). Prior to federal service, Ryan spent two field seasons with Oregon Department of Fish and Wildlife working on a population assessment of Oregon coastal coho using screw traps, electro fishing, and adult ladder traps.

Ryan has a B.S. in Fisheries Science from Oregon State University. In his spare time he likes to attend Oregon State football games and renovate his 1970's ranch home.
