Inuit Knowledge of Beluga Whale (Delphinapterus leucas) Foraging Ecology in Nunavik (Arctic Quebec), Canada

The beluga whale (Delphinapterus leucas (Pallas, 1776)) is expected to be influenced by changes in the environment. In Nunavik, the Arctic region of Quebec, Nunavimmiut (Inuit of Nunavik) have depended on beluga for centuries developing an extensive understanding of the species and its ecology. Forty semi-directive interviews were conducted with Inuit hunters and Elders from four Nunavik communities, who had a range of 28 to 47 years of beluga hunting experience. Interviews followed an ethnocartographic format and were analyzed using a mixed methods approach. Hunters most commonly reported prey species from the sculpin, cod, salmon, and crustacean families; regional variations in prey as well as foraging habitat were found. Hunters identified significant changes in body condition (i.e. blubber thickness), which were associated with observations about the seasonality of feeding. The timing of fat accumulation in the late fall and winter coupled with the understanding that Hudson Bay is not known as a productive area suggest alternate hypotheses to feeding for the seasonal movements exhibited by these whales. Inuit Knowledge of beluga foraging ecology presented here provides information on diet composition and seasonality of energy intake of the beluga and can be an important component of monitoring diet composition for this species into the future.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
