Giant mussels from China are invading the Hérault

France 3/Scoop, Feb 11

Giant mussels from China are invading our rivers, and having a huge impact on biodiversity.

Biologist Vincent Prié is sounding the alarm.

Freshwater mussels are threatened by a lot of things - human activity, pollution, and today an invasive species from China. The Chinese mussels were introduced accidentally in the 1980’s in the Camargue.

They are spreading like wildfire all over France. They were first introduced in Europe in Romania by fish, because the peculiarity of this species is that they make larvae which gets into the bronchial tracts of fish and develop there.

Smaller European mussels are no match for Chinese mussels. It is not a question of size but of reproduction. The Chinese mussel creates a lot more larvae than European mussels, and they are replacing our indigenous molluscs.
