Maeghen Wedgeworth, M.S.

Fisheries Biologist

B.S. Biology; M.S. Natural Resource and Ecology Management

 

West Sacramento, California

Maeghen is a fisheries biologist with experience in both freshwater and estuarine fish research including abundance estimation, occupancy relationships, mark-and-recapture, and life history studies. She recently served as an inshore fisheries biologist for the South Carolina Department of Natural Resources – Marine Resources Research Institute where she conducted long-term population monitoring of freshwater and estuarine finfish, sharks, turtles, and marine mammals. She has diverse field survey experience including snorkel, eDNA, radio-telemetry tracking, electrofishing, seine net, trammel net, gill net, longline, drumline, and trawl gears. She is an experienced boat operator in rivers, deltas, bays, and nearshore waters. Additionally, she is experienced in laboratory techniques including otolith, fin-ray, microplastics, and histological sample processing and staging. Maeghen also has experience managing and analyzing fisheries abundance, occupancy, life history, and hierarchical data using RStudio, SAS, and JAGS programs. During her graduate career, she developed protocols and led research on Prairie Chub abundance and life history relationships in the Red River basin of Texas and Oklahoma.
