Being in a comparatively cold climate with a short summer season, it may take Atlantic salmon parr up to eight years before they become smolt and migrate to sea. In addition, some populations of these Atlantic salmon, such as in the Koksoak (#91) and the Nastapoka (see below), consist of some fish which spend the summer in the estuary like sea trout, and others which are truly anadromous, migrating to feeding grounds off west Greenland.

Note: Shown in the lower left corner on this map is another far northern river, the Nastapoka, about half way up the east coast of Hudson Bay, which has Atlantic salmon.
