William Francis Ganong, New Brunswick biologist and historian, wrote: Gaspereau, or Gasparot. Name of a common salt-water fish of Acadia (also called alewife), first used, so far as I can find, by Denys in 1672. Nowhere can I find any clue to its origin. It seems not to be Indian. Acadians named two rivers after the fish, the Gaspereau River in Nova Scotia and the Gaspereaux River in New Brunswick. In eastern Massachusetts, Alewife Brook flows through Arlington,
Alewife taxa ("Bythotrephes longimanus", "Leptodiaptomus ashlandi", "Leptodiaptomus minutus", "Leptodiaptomus sicilis", and "Leptodora kindtii"). Alewife populations have seen big declines throughout much of their range. Several threats have most likely contributed to their decline, including loss of habitat due to decreased access to spawning areas from the construction of dams and other impediments to migration, habitat degradation, fishing, and increased predation due to recovering striped bass populations. In response to the declining population trend for alewives, the states of Massachusetts, Rhode Island, Connecticut, Virginia, and North Carolina have instituted moratoria on taking and possession.
