Jack Eschenroeder

Jack is a fisheries biologist with experience in a variety of freshwater systems, including delta and coastal environments. He has coordinated field monitoring programs in the Salinas, Carmel, and Guadalupe River watersheds. Jack is proficient in a wide range of methodologies, including the use of unmanned aerial systems (UAS), passive integrated transponder (PIT) tag antenna systems, eDNA and genetic techniques, automated fish passage monitoring systems, and acoustic telemetry transmitters, including JSATS acoustic tags in juvenile salmon. His sampling experience also encompasses boat, backpack, and barge electrofishing; hook-and-line sampling; Kodiak, midwater, oblique, and benthic trawls; and trammel, drift, gill, fyke, hoop, and seine nets.

Jack is experienced in the use of R statistical software to conduct analyses and create data visualizations, as well as GIS software for analyzing spatial data and creating maps. He regularly writes reports and develops communication materials for multiple websites and social media platforms operated by FISHBIO. Jack holds a master’s degree in biology from Georgia Southern University, where he studied the studied hybridization of an endemic freshwater fish species with an invasive congeneric relative, and assessed the effects of anthropogenic alterations of the watershed on contemporary genetic diversity.
