The Arctic cisco is the most northerly of cisco/whitefish species, existing in both salt and fresh water. This species has historically been called the Arctic cisco. However, unlike other ciscoes, which are primarily plankton feeders, this cisco is a predator, an extremely aggressive biter and will take just about any artificial lure cast in its direction. Residents of the community of Kugluktuk at the mouth of the Coppermine River in Nunavut, Canada call this species “whitefish” and do not differentiate it between any other species of whitefish. There, they are caught as a by-catch while subsistence or sport fishing for Arctic char, and mostly fed to their dogs despite bearing a flesh that is similar in taste and consistency to lake whitefish.
