Response Statement - Atlantic Salmon, Quebec Eastern North Shore population
This species requires rivers or streams that are generally clear, cool and well-oxygenated for reproduction and the first few years of rearing, but undertakes lengthy feeding migrations in the North Atlantic Ocean as older juveniles and adults. This population breeds in rivers along the north shore of the St. Lawrence River estuary from the Napetipi River (not inclusive) westward to the Kegaska River (inclusive). This population shows opposing trends in the abundance of small (1 sea-winter) and large (multi-sea-winter) fish. Small salmon have declined 26% over the last 3 generations, whereas large salmon have increased 51% over the same period; pooling the data for both groups suggests a decline of about 14% for all mature individuals considered together. The small size of the population, about 5000 mature fish in 2008, is cause for concern. As is the case for most populations of the species, poor marine survival related to substantial but incompletely understood changes in marine ecosystems is also a concern.
