The spread rates of alien species of Amphipoda and Mysida were calculated for the Dnieper, Pripyat and Neman rivers in the territory of Belarus. The maximal values of spread rate were obtained for Dikerogammarus villosus (in the Pripyat River - 37.8 km/year, in the Dnieper River - 17 km/year) and Dikerogammarus haemobaphes (in the Pripyat River - 53.6 km/year, in the Dnieper River - 17 km/year), while the minimal values of spread rate were calculated for mysids Paramysis lacustris (in the Dnieper River - 0.4 km/year) and Limnomysis benedeni (in the Dnieper River - 0.6 km/year), also for amphipods Chelicorophium robustum (in the Dnieper River - 0.5 km/year) and Echinogammarus trichiatus (in the Dnieper River - 1.3 km/year). The differences in the spread rates of species connected with the time of their first records at the monitoring points and the intensity of economic activities in the studied rivers.

In the River Tisza, the longest tributary of the Danube,Limnomysis benedeniCzerniavsky, 1882 had been the only mysid recorded until recently. In 2011, we found a few juvenile specimens ofHemimysis anomalaG. O. Sars, 1907 in two daytime samples taken from the Hungarian river section. During the overnight survey in 2012 aimed at revealing the actual distribution of this nocturnally active species, its most upstream occurrence was detected at Szolnok (river km 334).Paramysis lacustris(Czerniavsky, 1882) was also found at every sampling site of the river downstream of Tiszabercel (rkm 568), representing the first record of the species for the fauna of Hungary, and its most upstream self-sustaining population in the basin of the River Danube (1759 rkm from the Danube mouth).P. lacustrisis the fourth Ponto-Caspian mysid that has begun to expand its range spontaneously in the Danube catchment afterL. benedeni,H. anomala, andKatamysis warpachowskyiG. O. Sars, 1893. Due to its zooplanktivory it can be anticipated to have a considerable effect on the composition and abundance of the zooplankton assemblages and it may also become an important food source for certain fish species, especially in the impounded reaches and in stagnant or slow-flowing backwaters.P. lacustris — similarly toH. anomala — shows a diel vertical migration, moving to shallow waters only by night, which calls for increased attention in order to reveal its possible future range expansions. Although the River Tisza itself is not connected directly to other river basins via canals, it may potentially contribute to the further spread of the species (e.g., via fish stocking).
