eDNA emerges as powerful tool for tracking threatened river herring in Chesapeake Bay

(University of Maryland Center for Environmental Science) Using environmental DNA (eDNA) to track the presence of fish in waterways is emerging as a powerful tool to detect and understand the abundance of species in aquatic environments. Researchers from the University of Maryland Center for Environmental Science and Smithsonian Environmental Research Center field tested using eDNA -- tracking the presence of fish by identifying DNA that has been left behind in the water -- to detect river herring in tributaries of Maryland's Chesapeake Bay.
