Assessment rationale/justification
Calculations by the Species Specialist Subcommittee, based on survey estimates for some areas and informed judgements for others, suggest a total population in the order of 15,000 (6000 West Greenland, 1000 Gulf of St. Lawrence, 3000 Scotian Shelf, probably at least 5000 Newfoundland/Labrador = 15,000). Although the hunt in West Greenland may involve the same stock that occurs in eastern Canadian waters, recent and current removals are likely sustainable, given that the annual catch quota is 175, representing an offtake of ca. 0.01, which does not exceed replacement. Human-caused mortality from other potential threats does not exceed replacement.; Des calculs effectués par le Sous-comité de spécialistes des espèces, reposant sur des dénombrements estimatifs pour certaines aires et sur des opinions éclairées pour d'autres, indiquent que la population totale serait de l'ordre de 15 000 (6 000 individus dans l'ouest du Groenland, 1 000 individus dans le golfe du Saint-Laurent, 3 000 individus sur le plateau néo-écossais et probablement au moins 5 000 individus à Terre-Neuve-et-Labrador, pour un total de 15 000). Bien que la chasse dans l'ouest du Groenland puisse toucher la même population que celle des eaux de l'est du Canada, le nombre de captures récentes et actuelles semble durable, étant donné que le maximum annuel de prises est de 175, ce qui représente un coefficient d'environ 0,01 et n'excède pas le seuil de remplacement. La mortalité attribuable à l'humain par d'autres menaces potentielles ne dépasse pas le seuil de remplacement.
