Invasive crustaceans in the Rhine river

Two invasive crustacean species are expanding in the Rhine river; see also here.

One of them is a copepod, Chelicorophium curvispinum, originally from the Black Sea.

The other species, originally from the Danube river, is the gammarid Dikerogammarus villosus.

Both species reached the Rhine through the Rhine-Danube canal.

Both species may become pests.

However, predators of these species, goby fish, have also found their way from the Danube to the Rhine.
