Marshal Hoy, a Biological Science Technician, angling on Ross Lake for Western Fisheries Research Center (WFRC) food web study in October 2021. As a part of this study, fish are sampled for stomach contents, scale samples to assess age and growth, and fin tissue for stable isotopes and genetic analysis.
