ABSTRACT

New data on biology and morphology of the isolated population of the Baikal grayling Thymallus baicalensis from the mountainous Gitara Lake are given. The features were determined that distinguish it from other populations of the species inhabiting the Lake Baikal and mountainous water bodies of the Baikal-Sayan region, which is the result of adaptation to extreme conditions of the ultraoligotrophic lake and isolation from other populations of the species.
