Yury Dyldin, a scientist at the TSU Biological Institute, initiated a large-scale study of the diversity of freshwater fish and marine species entering the fresh waters of the Russian Federation and adjacent regions. The audit carried out by scientists from Russia, the Czech Republic and Germany showed more than 300 previously unrecorded species in the Russian Federation. The findings are presented in the Kyoto University Research Information Repository.
As the TSU ichthyologist notes, quantitative data on fish biodiversity are based mainly on studies in the middle of the last century with minor additions, which gives extremely erroneous data on the true state of Russian ichthyofauna. A group of scientists that included specialists from the three countries, including one of the most recognized ichthyologists in the world, Ronald Fricke (Germany), analyzed a large array of information regarding the ichthyofauna of the Russian Federation.
