The Petitcodiac River’s marine species have been severely impacted by the construction of the causeway in 1968. By the end of the 1980s, at least six species had completely disappeared from the watershed, including Atlantic sturgeon, American shad and the distinct Inner Bay of Fundy Atlantic salmon, since declared endangered in Canada.
This list also includes the Dwarf Wedgemussel, which used to live in abundance in the Petitcodiac River, its sole known location in the country. Today, this small mussel is extirpated from Canada and found in only nine American watersheds. Its elimination is attributed to the Petitcodiac causeway.
The education poster that follows, produced by Riverkeeper in 2005, lists the various marine species of the Petitcodiac. The restoration of fish passage at the Petitcodiac causeway will allow most of these species to be re-established in our ecosystem.
