Every year, over half a million river herring swim from the Boston Harbor up the Mystic River to lay eggs in fresh water. This amazing wildlife story is largely invisible. Join us and discover the remarkable story of river herring on the Mystic River and how the numbers from last year’s migration add to this story.

Find out about river herring lifecycle, the Mystic River, and hear from scientists studying the fish all across the state. We’ll also talk about how YOU can be involved in gathering data in-person this spring and through our web-based community science project.
