Biography

Jill Janak is a Post Masters Research Associate who joined the Ecology group in 2010. Jill assists with the maintenance and care of the Aquatic Research Laboratory (ARL), where salmonids, sturgeon, and other fish species are raised and held for use in laboratory and field studies. Jill’s main area of research is fish hard part geochemistry, which uses the hard parts of fish such as otoliths (ear bones) and fin rays to determine provenance, migratory, and environmental history. Jill also supports a variety of research projects that assess the effects of hydropower on fish, including radio and acoustic telemetry studies to assess survival of migrating salmon passing through hydropower facilities, as well as biological responses of fish to tagging and surgery.
