Fish species in need of conservation in Primorsky Krai, Russian Far East (for the regional Red Data Book update)

Based on the results of long-term monitoring of the freshwater and coastal marine ichthyofauna of Primorsky Krai, the list of rare fish species in need of protection for the new version of the regional Red Data Book has been critically revised. The new list includes only two threatened species – Sakhalin sturgeon, Acipenser mikadoi, and Sakhalin taimen, Parahucho perryi, which were also listed in the Federal Red Data Book published in 2021. The other 29 fish species listed in the former Red Data Book of Primorsky Krai (2005) were removed from the list for various reasons, which are discussed in detail in this publication.
