Description:

Bowhead whales, the only "true" arctic baleen species, are large rotund whales with a range confined to

icy arctic and sub-arctic seas. The four bowhead populations, or "stocks" in management terms, are

named for the seas they inhabit: Okhotsk Sea (OKH; ~218 individuals); the East Greenland, Svalbard,

Barents Sea (EGSB; ~318 individuals); the East Canada-West Greenland Sea (ECWG; ~6,400 individuals);

and the Bering-Chukchi-Beaufort Seas (BCB; ~16,800 individuals) (Fig. 1; Givens and Heide-Jørgensen

2021; Baird and Bickham 2021). All populations were hunted to near-extinction by commercial whaling,

which ceased by the early 1900s, but the two last mentioned have nearly fully recovered. Their

conservation success story was made possible by the productive collaboration of international

organizations, Indigenous hunters, non-governmental organizations, and national governments (Suydam

and George 2021). The two smaller populations have not recovered and are considered at high risk by

the International Union for Conservation of Nature (IUCN; Givens and Heide-Jørgensen 2021).
