Model estimates of Cumberland Sound beluga (Delphinapterus leucas) population size and total allowable removals [electronic resource] / Marianne Marcoux and M.O. Hammill. Title at head of French abstract: Estimations modélisées de la taille de la population de béluga de la baie Cumberland (Delphinapterus leucas) et des prélèvements totaux autorisés Ottawa : Fisheries and Oceans Canada, c2016. iv, 35 p. : map, tables, graphs.

"The subsistence harvest of Pangnirtung, Nunavut, is directed towards a single stock of belugas (Delphinapterus leucas) in Cumberland Sound, which forms a separate stock among belugas in the Canadian Eastern Arctic. A population model incorporating updated information on harvest statistics (1920–2015) was fitted to four aerial survey estimates using Bayesian methods, resulting in a current estimated population of 1,000 (rounded to the nearest 100) animals. The management objective is to achieve a population of 5,000 animals by 2091. This could be expressed as an interim target of 1,235 animals within a decade (2026). At current reported harvest levels of 41 animals, the probability of the population declining over a 10-year period is 1. The probability that the population would increase to the interim target was 0.3, 0.25 and 0.1 for reported harvests of 0, 6, and 25 animals respectively" - Abstract - p.iv.
