River Herring (IMAGE) University of Massachusetts Amherst Caption New England has an exceptional network of river herring wardens and other citizen science groups who for many decades have kept track of important life cycle dates and counted numbers of these and other fishes in the Gulf of Maine as they move up rivers to spawn. A new study led by UMass Amherst marine ecologists urges climate change researchers to make more use of such phenological records in marine species.
