The fish assemblage of the left Dnipro tributaries – the rivers Supij and Trubizh is described. The total collected 3242 specimens. Studies were conducted in 2011 and 2015 in Kyiv and Cherkasy regions. We analyzed materials from collections of National museum of natural history NAS of Ukraine (Kyiv) also. In Supij are found 21 species, in Trubizh - 22 species. The fish assemblage includes three introduced species, the stone moroko Pseudorasbora parva (Temminck et Schlegel, 1846), the Prussian carp Carassius (superspecies auratus) (Linnaeus, 1758) and Chinese sleeper Perccottus glenii Dybowski, 1877. In both rivers the most numerous species was the European bitterling Rhodeus amarus (Bloch, 1782). Dominant fish are phytophilic ecologic groups, eurytopic species, benthophags. In our studied rivers disappeared some native species (with comparison 1970-th): Leuciscus idus (Linnaeus, 1758), Aspius aspius (Linnaeus, 1758), Chondrostoma nasus (Linnaeus, 1758), and species listed in the Red Book of Ukraine: Leuciscus leuciscus (Linnaeus, 1758), Carassius carassius (Linnaeus, 1758), Gymnocephalus baloni Holcik & Hensel, 1974. However, there are some 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, Romanogobio belingi (Slastenenko, 1934), Misgurnus fossilis (Linnaeus, 1758). This allows us to take some reserved sites on rivers Trubizh and Supij as objects of Emerald Network.
