На о. Тюленьем за этот период погибает в среднем 7,9 % щенков, на Командорских островах – 14,4, на о-вах Прибылова – 9,8 %. Повышенные показатели смертности щенков на Командорских островах определяются заболеванием их унцинариозом на Северо-западном лежбище. Причины гибели щенков для разных мест их рождения сходны, основными из них являются истощение, травмы, болезни.</p></abstract><trans-abstract xml:lang="en"><p>Mortality rate of fur seal puppies is considered for the first two months of their postnatal ontogenesis, from the birth to leaving the rookery on Tyuleniy Island for wintering in the open waters of the Pacific. On average, 7.9 % of puppies die on the island, that is lower than the mortality on the rookeries on Commander Islands (14.4 %) and on Pribylov Islands (9.8 %). The higher mortality of puppies on Commander Islands is reasoned by their disease with uncinariosis at the northwestern rookery. In general, deaths of puppies have similar causes in different places of their birth: mainly exhaustion, injuries, and diseases.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>северный морской котик</kwd><kwd>смертность</kwd><kwd>причины гибели</kwd></kwd-group><kwd-group xml:lang="en"><kwd>northern fur seal puppy</kwd><kwd>mortality</kwd><kwd>cause of death</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Автор благодарит А.М.
