Herring Count Volunteer [End of March- early June]

Location: Plymouth, MA
Sanctuary: Tidmarsh

River Herring, Alewife and Blueback Herring are anadromous fish or migratory fish that live in the ocean and move into our rivers, lakes and ponds, including Beaver Dam Brook and Fresh Pond, to spawn as adults. The juvenile fish then return to the estuaries and then to the ocean to live as adults. Herring counting helps document the number of herring coming to spawn in the stream to help research on the restoration project.
