Assessment rationale/justification
Numbers of belugas using Cumberland Sound have declined by about 1500 individuals between the 1920s and present. The population decline is believed to have been caused by hunting by the Hudson Bay Company into the 1940s and by the Inuit until 1979. Hunting has been regulated since the 1980s. Current quotas (41 in 2003) appear to be sustainable. Concerns have been raised about increased small vessel traffic and the associated noise of outboard motors, as well as fishery removals of Greenland halibut, a food of belugas.; Le nombre de bélugas utilisant la baie de Cumberland a connu un déclin d'environ 1500 individus entre les années 1920 et aujourd'hui. La chasse par la Compagnie de la Baie d'Hudson jusque dans les années 1940 et la chasse par les Inuits jusqu'en 1979 semblent être la cause du déclin. La chasse est réglementée depuis les années 1980. Les quotas actuels (41 en 2003) semblent être durables. Des préoccupations concernant le trafic accru de petites embarcations et le bruit des moteurs hors bord qui leur est associé, ainsi que la pêche au flétan noir, un aliment consommé par le béluga, ont été soulevées.

History
The Southeast Baffin Island-Cumberland Sound population was designated Endangered in April 1990. In May 2004, the structure of the population was redefined: the Southeast Baffin Island animals (formerly part of the Southeast Baffin Island-Cumberland Sound.; La population du sud-est de l'à®le de Baffin et de la baie Cumberland a été désignée ' en voie de disparition ' en avril 1990. En mai 2004, la structure de la population a été redéfinie : les individus du sud-est de l'à®le de Baffin (appartenant autrefois à la population du sud-est de l'à®le de Baffin et de la baie Cumberland) ont été ajoutés à la population de l'ouest de la baie d'Hudson. En mai 2004, la population de la baie Cumberland, nouvellement définie, a été désignée ' menacée '.
