Alewives reach a maximum length of about 40 centimeters (16 in), but have an average length of about 25 centimeters (10 inches). The front of the body is deep and larger than other fish found in the same waters, and its common name is said to come from comparison with a corpulent female tavernkeeper (“ale-wife”).
Alewives are perhaps best known for their invasion of the Great Lakes by using the Welland Canal to bypass Niagara Falls.–Wikipedia
