[Helminthofauna of Steller's sea lion (Eumetopias jubatus) inhabiting the north-eastern coast of Asia].

Helminths collected from 55 Steller's sea lions in the western and central Bering Sea were examined. Helminth species, their localization in the host organism, invasion indices, categories, and host ranges are reported. Helminthofaunas of sea lions from various sea areas are compared. Forming of the recent Steller's sea lion helminthofauna and its links with other host are discussed. It was hypothesized that helminths do nor substantially affect the recent decline of the Steller's sea lion abundance.
