that establish territories in ice covered areas, whereas the juvenile seals<br />

mainly spend the winter in areas with loose unconsolidated sea ice.<br />

<strong>The</strong> catches in the assessment area have been around 3,000 animals per year<br />

since 2003 (this has been a warm period). Catches were, however, about<br />

three times higher during the last cooling period in the 1990s when the packice<br />

from the <strong>Davis</strong> <strong>Strait</strong> was closer to the coast and the extent of sea ice in<br />

the fjords was larger.<br />

Conservation status: <strong>The</strong> ringed seals in general have a favuorable conservation<br />

status, because they have a relatively uni<strong>for</strong>m and widespread circumpolar<br />

distribution, which prevents overexploitation on an overall population<br />

level. Ringed seals are listed as of Least Concern (LC) on the Greenland Red<br />

List.<br />

Sensitivity: Breeding ringed seals depend on stable sea ice during the 2<br />

months when they give birth and nurse their pups. This stationary behaviour<br />

makes them vulnerable to disturbance and particularly to activities<br />

that can disrupt the stable ice. However, ringed seals were not particularly<br />

shy towards seismic operations in Arctic Canada, where they showed only<br />

little avoidance of the ships (Lee et al. 2005). Ringed seals can be affected by<br />

oil spills in the same way as all other seals (i.e. tissue damage and poisoning).<br />
