Alewife \Ale"wife`\, n.; pl. {Alewives}. [This word is properly aloof, the Indian name of a fish. See Winthrop on the culture of maize in America, ``Phil Trans.'' No. 142, p. 1065, and Baddam's ``Memoirs,'' vol. ii. p. 131.] (Zo["o]l.) A North American fish ({Clupea vernalis}) of the Herring family. It is called also {ellwife}, {ellwhop}, {branch herring}. The name is locally applied to other related species.
The predator brought the alewife population in check, and the salmon began to grow so large that sport fishermen paid big money to catch them.
But the goby doesn't appear threatening, unlike a host of other invaders, including the water pipe-clogging zebra mussel, the trout-killing sea lamprey, and the beach-befouling alewife.
Chinook salmon, introduced into Lake Michigan more than 25 years ago to control an alien alewife population, are the dominant sport fish in the lake and make up more than half the catch, according to Wisconsin record keepers.
The alewife population exploded.
Now, suddenly, the alewife population has diminished, causing the average size of salmon reeled in to drop to eight pounds from 11 pounds.
