Presumpscot River Alewives
Each spring, alewives migrate up coastal brooks and rivers from the Gulf of Maine to spawn in their natal ponds. This massive concentration of ocean fish coming into freshwater is a great boon the inshore and riverine ecosystems, providing highly caloric meals for every predator that can get their mouths around them, from eagles, to seals, to raccoons. Humans, too, get in on the action and use alewives as bait for lobsters and halibut, and even eat them smoked as a traditional snack. Alewife numbers have declined in recent years, but our monitoring efforts on local rivers ensure that the best available science is used by managers.
