Alewife Migration Walk
10 AM–12 PM | Mill Brook Preserve, Westbrook | PublicThe Gulf of Maine Research Institute and Presumpscot Regional Land Trust invite you to join us for a unique opportunity to observe and collect data on alewives during their annual spawning run.

The Gulf of Maine Research Institute and Presumpscot Regional Land Trust will lead a walk during the annual alewife migration season at Mill Brook Preserve in Westbrook. The walk will be a two-mile round-trip on uneven, hilly terrain. GMRI Research Scientists, Zach, and Aaron, will guide us through the process of observing and collecting data on these fascinating fish while Brenna, from the Presumpscot Regional Land Trust, will talk about the importance of preserving critical habitat.
During the event, we'll discuss the significance of the alewife to our ecosystem and the challenges they face during their spawning run. We'll also learn about the methods used by scientists to collect data on these fish and how the data help us gain a better understanding of the pace and direction of these changes taking place in the coastal marine fishery ecosystems that support our region.
No prior experience or scientific background is necessary to attend this event. All are welcome to register and learn about the alewife and the important role they play in our environment. Parking is limited and information will be shared with registered participants.
