River Herring

river herring

Over the past 300 years, what had been a bountiful harvest of river herring declined for many reasons including dam construction and poor water quality. In the late 20th century, herring populations sharply dropped to as little as one percent of their historic size.

Woods Hole Sea Grant is working in partnership with conservationists, river herring wardens, and others to monitor the population, to study it to understand the pressures on the species, and to develop solutions to help increase its numbers.
