Jesse has nearly a decade of experience working in fisheries. His diverse background allows him to contribute to a variety of CFS projects spanning multiple biological disciplines. Jesse has served as the lead biologist on predation assessments, otolith microstructure studies, as well as numerous restoration monitoring projects to benefit salmonids. His analytical experience includes macroinvertebrate and fisheries community analysis, genetic analysis, and otolith microstructure analysis. His other experience includes PIT tag antenna arrays, electrofishing, stomach content analysis, salmonid carcass and redd surveys, rotary screw trapping, seining, trawling, and snorkel surveys. Jesse is an expert at identifying California’s diverse fishes, and an experienced boat operator in lakes, rivers, and deltas.
