Analysis reveals shifts in species status and conservation measures for lampreys and fishes in Russia.
The sections on lampreys and fishes in three editions of the Red Data Book of Russia (1983, 2001, and 2021) have been analyzed. Changes in species composition and the reasons that caused them are considered. The history of the formation of categories of rarity and endangerment statuses in the Russian Red Data Books and their close connection with the Red Data Book and the International Union for Conservation of Nature Red List is shown. The need for categories of conservation status (I, II, and III priorities of conservation measures) is considered. Changes in approaches to listing species in different editions are analyzed. A number of problematic issues in maintaining the Red Data Book of Russia are noted. Proposals are put forward for the formation of a list of lamprey and fish taxa to be listed in the next edition of the Red Data Book of Russian Federation and the selection of status categories for them.
