R-24-26-Wilson Using hydroacoustics to support shad and river herring management

Karen Wilson
University of Southern Maine

Data for management of juvenile American Shad and river herring (alosines) in the Kennebec River is generally limited to abundance as determined by Maine Department of Marine Resource (MDMR’s) annual beach seine surveys. This project will augment these data by leveraging MDMR’s survey to collect fish samples for a better understanding of the ecology (e.g., diet, growth, residency) of these juveniles and will use the survey data to complement a proof-of-concept hydroacoustic survey of alosine abundance in deeper areas.
