Such species as: Caspiosoma caspium (Kessler, 1877), Knipowitschia cameliae Nalbant et Otel, 1996, Neogobius ratan (Nordmann, 1840), Neogobius syrman (Nordmann, 1840), Benthophiloides brauneri Beling et Iljin, 1927 have not been identified by us, but are mentioned in other scientific sources (Ganea et al., 1981; Cozari et al., 2003; Romanescu, 2012; Moșu et al., 2013). Comparative analysis of the gobiidae ichthyofauna from Dniester River and Prut River revealed a greater diversity and abundance of Gobiidae in the Dnister River than in the Prut river, 10 species versus 6 species. The relative abundances of Gobiidae species in the Lower Dniester sector for the year 2018 captured with juvenile catching trap are: N. fluviatilis (Pallas, 1814) – 4.13%, N. kessleri (Gunther, 1895) – 3.96%, N.
