. The Canadian field-naturalist. 392 The Canadian Field-Naturalist Vol. 102. Figure \. Male Narwhal, Monodon monoceros, with tusk (Drawing by Campet; courtesy Department of Fisheries and Oceans). Three stocks of Narwhals (one summering in northwest Greenland, one in the Canadian High Arctic, and one in northwestern Hudson Bay) have tentatively been recognized for management purposes by the Department of Fisheries and Oceans (DFO), Central and Arctic Region, within the overall aggregation that winters in Davis Strait/Baffin Bay. It is not clear, however, if these stocks are unique entities exhibiting breeding and site fidelity or if there is interchange of individuals or groups. The best known stock is that of the High Arctic which occurs in the waters and deep fiords of Baffin Bay, between western Greenland and Baffin Island, and throughout the eastern Canadian Arctic Archipelago (Mansfield et al. 1975). Known summer concentrations (Figure 2) occur in Eclipse Sound, Admiralty Inlet, Prince Regent Inlet, and Peel Sound. Lancaster Sound appears to be a major travel route to and from summer concentration areas rather than a summering area. The northwestern Hudson Bay stock occurs in the vicinity of Repulse Bay in Foxe Channel and near southern Southampton Island. The affiliation of Narwhals occurring in northern Foxe Basin is unclear, although an apparent gap in distribution between Hall Beach and Foxe Channel suggests they are part of the High Arctic stock. Narwhals have been observed wintering in the pack ice of Baffin Bay, Davis Strait (McLaren and Davis 1983), and the Disko Bay area of West Greenland (Vibe 1967; Kapel 1975,1977). Small numbers may winter in Hudson Strait (MacLaren Marex Inc. 1979a, 1979b; McLaren and Davis 1981; Finley and Renaud 1980). The range and distribution of the Narwhal may be directly related to long-term temperature fluctuations and the resultant ice cover (Vibe 1967).
