Brief description

Dikerogammarus haemobaphes (Eichwald, 1841) is a species of freshwater gammarid crustacean. These gammarids are commonly known as demon shrimp, likely because they are an extremely successful invasive species. Native to the Ponto Caspian basin, Dikerogammarus haemobaphes expanded their range in the 1950s. This expansion began in Lake Balaton, Hungary and then spread into certain rivers and lakes in Austria, Belgium, Germany, Poland, Russia, Ukraine, and the United Kingdom. These crustaceans likely broadened their range due to the interconnection of waterways in Europe and the use of transportation vectors such as boats and ships (Wikipedia contributors, 2023).

Status and distribution in Luxembourg

The species was recorded in 2008/2009 in the French part of the Moselle (Labat et al. 2011), and was detected in the Moselle in Luxembourg in both 2018 and 2024 during monitoring by the LfU Rhineland-Palatinate State Office for the Environment.
