Unique wildlife:
Lake Baikal is rich in
wildlife. Nearly 300 species of birds
nest around the lake, and many more stop off on their seasonal migration,
especially in the marshy delta of the Selenga River. White-tailed eagles patrol the shores for
carrion, and brown bears are forest residents.
More than a third of plant and animal species living here, such as the
Baikal sturgeon, are found nowhere else in the world.
Baikal’s most famous residents are
the steel-grey nerpas, a species of freshwater seal. How seals came to be here is a mystery,
although scientists speculate that they swam up rivers form the Arctic Ocean
and were cut off from the sea during the last Ice Age. When the ice melted they never went back, but
became isolated in the lake. Nowadays,
seals can be seen basking on rocks on the Ushkany Islands and other central and
northern parts of the lake. Nerpas feed
mainly on golomyanka, or Baikal oilfish, the most common fish in the lake. These bottom-dwellers come close to the
surface to feed at night. Oilfish lack a
swim bladder but have a high oil content and porous bones, which allows them to
move up and down in Baikal’s water unaffected by changes in pressure.
Another notable resident of the lake
is the omul, a small, silver-sided, salmon-like fish occasionally caught by
nerpas and the primary catch of local fishermen. Smoked omul is a delicacy sold in markets
around the lake and popular with travellers; locals prefer their omul salted. A traditionally dish, known as stroganina,
consists of a salad of finely cut strips of freshly frozen, raw omul served
with onion, salt and black pepper.
