In 2000, a new pup production survey will be undertaken. New population and replacement yield estimates will be produced after results of the survey are available. A study of Arctic ringed seals has confirmed the existence of several distinct groups of ringed seals. The structure of the ringed seal population in Labrador is less well known. In response to a suspected population decline, a sampling program for ringed seals has begun in Hudson's Bay in cooperation with the Nunavut Wildlife Management Board.
Ringed seals are a critical prey item for polar bears in the North.
Consequently, any proposal for a commercial harvest of this species would have to take into account the potential impact on polar bears. There are few detailed estimates of ringed seal abundance for Canadian populations. Hunting of ringed seals is currently done for subsistence only. Other Seals There are no reliable population estimates for harbour and bearded seals. The scope and nature of environmental effects are considered when developing management plans.
