A male white whale caught in 2012 lived in artificial environment for six years and was released in Sakhalin Bay in August 2018 with a satellite tag attached. Moving along the west coast of Sakhalin, at a variable speed, reached its southern part in a month, passed the La Perouse Strait and spent some time in the waters of the northern part of the Hokkaido. Then he left Japan waters and, moving in the Sea of Japan far from the coast, reached the waters of South Korea. Having examined the coast, the male began to return to the shores of Russia, when the signal from his radio beacon disappeared. The tracked route of the male white whale is undoubtedly of scientific interest. Studying the migration route of the white whale, we can confidently state that it regained the skills of independent foraging, but, most likely, it moved alone and its route is not typical for the migration of wild white whales.
