title: [Parasites of the introduced Amur sleeper, Perccottus glenii (Osteichthyes): alpha-diversity of parasites and age of the host].
abstract: Three age groups of the Amur sleeper have been studied: underyearlings (0+), two-year-olds (1+), and three- and four-year-olds (2+ and 3+). The long-cycle parasites prevalent in all three age groups are the merocercoids of Ophiotaenia europaea, third-instar larvae of Spiroxys contortus, and metacercaria of Isthmiophora sp. and Prohemistomidae gen. sp. Different age groups of the Amur sleeper have different roles in the life cycle of O. europaea. Underyearlings are second intermediate hosts of O. europaea, and Amur sleepers aged 1+ and older are parathenic hosts. The alpha-diversity of long-cycle parasites of the Amur sleeper increases with the age of the host.
