First Records Of The Alien Amphipod Dikerogammarus Haemobaphes (Eichwald, 1841) In The Neman River Basin (Belarus)

The alien Ponto-Caspian amphipod Dikerogammarus haemobaphes, that is already well-established in the main rivers of the Belarusian part of the Black Sea basin, was recorded for the first time in the Belarusian part of the Neman River basin (Augustow canal in 2018 and Chornaya Hancha River in 2020). Most likely, this alien amphipod spread naturally and/or was introduced with boat hull fouling from the Polish part of the Narew River (Vistula River basin) via the Augustow canal. This species will invade the Neman River in the very near future.
