Abstract: The Danube between Harta (rkm 1549) and Kehlheim (rkm 2410) was sampled qualitatively in 1985-1995 at all seasons. Eighteen epigean species of Malacostraca (Janiridae, Asellidae, Gammaridae, Talitridae, Corophiidae, Mysidae, Astacidae, Cambaridae) were recorded. The malacostracan fauna shows a distinct longitudinal zonation in the River Danube. At least nine species are of Ponto-Caspian origin. The actual distribution patterns were analyzed with respect to former studies. At least six species were strongly expansive during the last few decades. Navigation appears to be among the crucial factors for this dispersion.
