Emily Jonagan

Emily Jonagan is a fisheries biologist with extensive fish population monitoring and freshwater ecology expertise. She earned a Bachelor’s in Environmental Science from Xavier University (2016) and a Master’s in Fisheries and Wildlife Sciences from Arkansas Tech University (2022), where her research focused on the genetic impacts of barriers on a migratory fish species in the Arkansas River. Emily has contributed to a wide variety of fisheries projects, including long-term monitoring programs on the Mississippi and Illinois Rivers with the Illinois Natural History Survey. She is proficient in multiple sampling techniques, including gill-, hoop-, fyke netting, trawling, seining, and electrofishing. Before joining FISHBIO, she worked on juvenile salmonid marking and coded wire tagging at Northern California conservation hatcheries.

At FISHBIO, Emily has led and supported numerous projects, including PIT tag and mark-recapture studies in the Calaveras and San Joaquin River watersheds. She recently led efforts to quantify fish entrainment during dredging operations in the Sacramento-San Joaquin River Delta and contributed to restoration-related biological monitoring on the Tuolumne River. She is proficient in the programming language R and has used MATLAB to process Acoustic Doppler Current Profiler (ADCP) data.
