Commercial and subsistence catches of beluga whales (Delphinapterus leucas) from Cumberland Sound, Nunavut, 1840-2016 / by D.B. Stewart. : Fs97-6/3250E-PDF
"A record of commercial and subsistence catches of beluga whales (Delphinapterus leucas) from the Cumberland Sound population in Nunavut, over the period 1840 through 2016, is presented. This work adds substantially to the catch record and improves the basis for population modelling to inform recovery planning. Commercial hunts in 1860 through 1966 removed at least 14,079 belugas from Cumberland Sound, and subsistence hunts another 2,765—mostly after 1960. Annual catches suggest a pattern of long-term depletion, with partial recovery related to a hiatus in commercial hunting around World War I, followed by continued depletion. Catches stabilized following formal harvest regulation in 1980. In some years the historical commercial catches were 15x greater than the current annual subsistence catches”--Abstract, p. vi.
