The-present number of Caàpian seals is estimated at from
500,000 to 600,000. With the aim .of more rational utilization Of .
the stocks, measures have been introduced to regulate killing and to
conserve the reproductive and potentially-reproductive members of
the Caspian Seal herd. The killing of adult females during the
breeding period has been totally prohibited since 1966, and the killing
of sexually-immature animals and pregnant females in the aui;umn
shore rookeries since 1967. An annual limit (of. 60,000-65,000) lhas
been placed on the killing of young of the year during the winter. .

with folds or wrinkles. The claws, unlike thoe pï other suais, are
long and stout, with a longitudinal ridge on the upper margin.
