The international journal DATA, under the leadership of Corresponding Member of the Russian Academy of Sciences A.A. Kotov, published the work of Russian and Chinese researchers summarizing the results of 20 years of monitoring of the ichthyofauna of the Volga and Kama rivers. The purpose of the study is to describe the diversity of alien and native fish of the Volga and Kama rivers (the largest water system in Europe).
For the observation period from 2001 to 2021. a database of almost two thousand records (more than 36 thousand individual observations) was compiled for coastal and pelagic habitats of 143 locations, covering 52 species from 42 genera of 22 families of bony fishes.
The dataset is in the standardized DarwinCore format and is publicly available on the International Biodiversity Database GBIF.
As a result of the work, data on new findings are provided and the distribution of alien fish species in the Volga-Kama basin is clarified. For all alien species, genetic diversity data (DNA barcoding) is provided, which will allow our data to be used as a comparison material for the accurate identification of alien fish species in order to control their spread.
The work was supported by the Russian Science Foundation (project 23-14-00178).
