Abstract

Abstract The fish fauna of the Gilmimliveem River (the Bering Sea basin) includes five taxa of species and subspecies ranks: Arctic grayling Thymallus arcticus signifer, resident (landlocked) dwarf Dolly Varden trout Salvelinus malma, relict three-spined stickleback Gasterosteus cf. aculeatus, the nine-spined stickleback Pungitius pungitius, and the western slimy sculpin Cottus cognatus cognatus. Arctic grayling and nine-spined stickleback were found for the first time. Two rare Beringian subspecies are recorded (T. arcticus signifier and C. cognatus cognatus) and a local endemic of Northeast Asia (G. cf. aculeatus). A morphological description, some features of the biology and current state of populations of freshwater fish of a unique ecosystem of thermal mineral springs of the Gilmimliveem River are presented for the first time. The linear growth of these fish on the Chukchi Peninsula of the Russian Arctic (the northeastern edge of the Asian continent) is discussed.
