Gudgeons of the genus Gobio (Pisces: Cyprinidae) in Central and Eastern Kazakhstan: the history of description, systematics and the current state of knowledge

Abstract

The current state of knowledge of the native freshwater ichthyofauna in Kazakhstan water bodies does not allow to
adequately assess its real diversity. The gudgeons of the genus Gobio are not an exception, as their taxonomy and phylogenetic
relationships remain poorly studied. Currently, they are of considerable interest of many ichthyologists. The present review
article examines the history of the description and the taxonomical problems of Gobio representatives from the Central and
Eastern Kazakhstan, as well as the available information on their biology. As a result of the analysis of literary sources, a
great lack of data on the taxonomy, relationships and biology of gudgeons in this region has been identified. At present, there
is a need to revise their taxonomy, as well as detailed investigation of various aspects of the biology of these representatives
of the Kazakhstan ichthyofauna.
