Several organizations are looking for volunteers to help monitor alewife runs in Maine’s rivers and streams.

Alewives spend the majority of their lives at sea and return to freshwater lakes and ponds every spring to spawn. The Maine Department of Marine Resources said in a statement that alewives are important because of their place in the food chain and because they serve as lobster bait.

The Bristol Mills Alewife Restoration Project is seeking volunteers to monitor alewife passage at Bristol Mills Dam on the Pemaquid River. The marine resources department is also looking for volunteers to monitor Flanders Stream in Sullivan. Interested parties should call Claire Enterline at (207) 350-6124.

The Kennebec Estuary Land Trust is also seeking volunteers at the Nequasset Dam in Woolwich. Information is available on its website.
