Introduced mussel species threatens Carinthian lakes

Quagga mussels have been present in Carinthia since 2022 and are now spreading. The mollusc from the Black Sea region has devastating effects.

The quagga mussel is becoming increasingly common in Austria. It was already discovered in Lake Ossiach in 2022, then in Lake Wörthersee and Lake Keutschach and now also in Lake Feldsee.
