North American Journal of Fisheries Management, 2016 Abstract The Arctic Char Salvelinus alpinus is widely considered the most important subsistence fish species in the Canadian Arctic. Throughout the species’ range, commercial fisheries for Arctic Char also exist, the management of which primarily follows river-specific harvest strategies. Such an approach, however, may not be appropriate

Mechanisms of co-existence of Heterocope saliens (Crustacea, Copepoda) and planktivorous fish
Fauna Norvegica, 1984 The simultaneous occurrence of Heterocope saliens and a large stock of Arctic char was investigated in the oligotrophic, coastal Lake Selura in SW Norway. Habitat-overlap of H. saliens and Arctic char was restricted mainly to June.
