Due to declining salmon stocks throughout the Maritimes, the Department of Fisheries and Oceans has instituted management restrictions over time. The following is a general timeline of the major restrictions.
1984 - All commercial salmon fisheries in the Maritimes and Quebec closed.
1984 - Mandatory catch-and-release of all large salmon in the Maritime provinces.
2000 - All commercial salmon fisheries in Atlantic Canada closed.
2002 - Greenland imposes moratorium on commercial fishing of Atlantic salmon.
2007 - Greenland extends salmon fishing moratorium until 2014.
The St. Mary's River Association collaborates with the federal Department of Fisheries and Oceans and the provincial Department of Fisheries and Aquaculure for fisheries management within the watershed. Such collaboration includes assisting with salmon stock assessments and providing comment on discussion papers.
