In October 2018, two adult females
of the Northern fur seal and one juvenile male were deployed with
satellite tags on the Tyuleniy Island in the Sea of Okhotsk. The
resulting operational time of the tags ranged from 33 to 203 days. The
adult females started their winter migration in the first half of
November; the initial stage of their winter migration occurred in the
Japan/East Sea, into which they entered through the La Perouse Strait.
The juvenile male left the rookery in mid-October, crossed the Sea of
Okhotsk in a wide arc in a north-western direction and returned to the
south. The male had reached the coastal areas of Japan by the end of
November. From the Sea of Okhotsk, the male entered the Pacific Ocean
through the Yekaterina Strait and subsequently entered the Japan/East
Sea via the Tsugaru Strait. The winter foraging of the male occurred
within the Japan/East Sea in coastal waters of Japan. After 3 months,
the male returned to the Pacific and remained off the Sanriku Coast
