Distribution of North Atlantic right whales, Eubalaena glacialis, in Eastern Canada from line-transect surveys from 2017 to 2022 / Anne P. St-Pierre, Talia Koll-Egyed, Valérie Harvey, Jack W. Lawson, Caroline...: Fs70-5/2024-059E-PDF

"North Atlantic Right Whales (NARW), Eubalaena glacialis, have been designated as "Endangered" by the Committee on the Status of Endangered Wildlife in Canada, and "Critically Endangered" on the International Union for Conversation of Nature (IUCN) Red List, due to their current small population and decline caused by commercial whaling and mortality from ship strikes and entanglement in fishing gear, as well as declines in productivity. … Information on the distribution and abundance of NARW in Canadian Atlantic waters was limited prior to the onset of targeted surveys in 2017 and broad-scale, repeated surveys in 2018. … This study presents results from the DFO Science NARW aerial surveillance program conducted from August 2017 to November 2022 across Atlantic Canada and focuses solely on NARW abundance and distribution. In particular, it presents the variability in abundance estimates among years and within the survey season each year. These results will contribute to providing advice on the spatial and temporal distribution of NARW in Canadian waters and to identifying potential areas where NARW occur across Atlantic Canadian waters, especially outside of the traditional areas in the Bay of Fundy and nearby Scotian Shelf (SS) waters"--Introduction, pages 1, 2.
