Great attention is given to investigation of invasive species, however, the fauna of the basin of the Don River in this respect has not been sufficiently studied. Until now, there is no generalized list of invaders of the Don basin, including the Lower Don. The fauna of decapod crustaceans of the Azov-Black Sea basin is well studied and has 52 species. For the Don River 3 species of Decapoda are known, including invasive crab Rhithropanopeus harrisii (Gould, 1841).
