The fish assemblage of the left Ross tributaries – the rivers Kamianka and Protoka is described. The total collected 2842 specimens. Studies were conducted in 2013 and 2020 in Kyiv and Zhytomyr regions. The current species composition includes 30 species for Kamianka and 20 species - Protoka. According to the research results, it has been established that the rivers are dominated by fish of the eurytopic ecological group, phytophils, zoobenthophages. It was found that the species composition in the studied parts of the Kamenka River is higher than in the Protoka River. This indicates the presence of a high level of biotopic diversity in comparison with other water bodies. In some areas studied there are species - from Resolution 6, adopted to create the Emerald Network. It’s such species as Rhodeus amarus (Bloch, 1782), Cobitis taenia (s.l.) Linnaeus, 1758, Misgurnus fossilis (Linnaeus, 1758). This allows us to take some reserved sites on rivers Kamianka and Protoka as objects of Emerald Network.
