Abundance estimates of narwhal stocks in the Canadian High Arctic in 2013 / T. Doniol-Valcroze ... [et al.].: Fs70-5/2015-060E-PDF
In summer, narwhals of the Baffin Bay population migrate to the fiords and inlets of northeastern Canada and northwest Greenland. Numerous Inuit communities across Nunavut hunt narwhals on their summering grounds or along their fall migration routes for subsistence. To prevent localized depletion, management of this population is based on summering aggregations. Abundance estimates for most of these stocks were dated while others were totally lacking or known to be incomplete. DFO conducted the High Arctic Cetacean Survey (HACS) in August 2013 to estimate abundance of all four Canadian Baffin Bay narwhal summer stocks as well as putative stocks in Jones Sound and Smith Sound. This is the first survey to count all of the narwhal stocks in the Canadian High Arctic during one summer. This document presents the results of the survey and new abundance estimates for the stocks, as well as updated estimates of Potential Biological Removals (PBR).
