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).A specimen of shrimp of the genus Macrobrachium Bate, 1868 was caught in the Don River in the vicinity of the mouth of the Manych River in 2017.This instance is predefined as Macrobrachium cf.rosenbergii (De Man, 1879).The most probable ways of appearance of this species in the Don are either industrial production in artificial reservoirs, using the water of the Don pool, or drifting into the river by aquarists.
