“…Anadromous (those that migrate between fresh water where they spawn and/or overwinter to marine habitats where they feed) coregonines such as broad whitefish (C. nasus), inconnu, lake whitefish, least, and Arctic cisco (C. sardinella and C. autumnalis) are harvested during their fall spawning migrations along western Arctic coastal rivers and especially in the Mackenzie River where a fishery estimated at 150,000 kg/year is taken for subsistence purposes [11]. Northern anadromous Dolly Varden Char (Salvelinus malma) are mainly subsistence fished in the Beaufort Sea coastal waters [12] and along the Mackenzie River system on their return migration from the coast (e.g., Aklavik and Fort MacPherson). Anadromous Arctic charr are harvested throughout the territory of Nunavut in all coastal communities as well as in the communities of Paulatuk, Ulukhaktok, and Sachs Harbour in the Northwest Territories.…”

“…Anadromous Dolly varden char (Salvelinus malma) are mainly fished for subsistence using gillnets in Beaufort Sea coastal waters of both Canada (Northwest Territories and Yukon) and Alaska [12]. They are also harvested in Inuvialuit and Gwich'in communities along the Mackenzie River system (e.g., Aklavik and Fort McPherson) on the return migration to headwater spawning/overwintering areas.…”

Migration occurs when key aspects of the life cycle such as growth, reproduction, or maintenance cannot all be completed in one location. The Arctic habitats are variable and Arctic species are often migratory. The predictable nature of migrations in both space and time allow Arctic people to harvest fishes and marine mammals. We describe migratory/dispersal behavior in four types of taxa from the Canadian Arctic: anadromous and freshwater fishes, marine fishes, marine invertebrates, and marine mammals. Patterns of migration are remarkably different between these groups, in particular between distances migrated, seasonal timing of migrations, and the degree of reproductive isolation. Migratory anadromous and freshwater fishes become adapted to specific locations resulting in complex life histories and intra-and inter-population variation. Marine mammals not only migrate longer distances but also appear to have distinct demographic populations over large scales. Marine fishes tend to be panmictic, probably due to the absence of barriers that would restrict gene flow. Migratory patterns also reflect feeding or rearing areas and/or winter refugia. Migratory patterns of harvested aquatic organisms in the Canadian north are extremely variable and have shaped the north in terms of harvest, communities, and culture.
