At lake Baikal, there are many holy places, whom an unusual power and mysterious history is assigned by the Buryatical inhabitants. Such a place are the Ushkanin islands which are situated at important place in the middle of the lake and which are a place of pilgrimage of biologists of all the world. The cause for that is the nerpa, or phoca sibirica, or Baikal seal - one kind of the family of seals that lives in fresh water. Until today scientists puzzle about the question how these creatures were coming into the lake Baikal. One presumption is that they were coming along the rivers in the north, up the river Jenissej to the spring of the Angara river and from there straight into the lake Baikal.
One thing is clear - the seals are here, in the lake Baikal. Their population consists of about 60,000 - 100,000 specimen. Neither an epidemic which was observed in the year 1987 nor the prohibited but practised hunt for the young seals in spring could make the seals die out. Until now.
