Invasive quagga mussel spreads across Austrian lakes

An invasive species known as the quagga mussel is rapidly spreading across lakes and waterways in Austria, raising concerns among aquatic ecologists and environmental authorities. Originally native to the Black Sea region, the mollusk disrupts native ecosystems, alters water chemistry, and causes biofouling on underwater infrastructure and recreational equipment.

Aquatic ecologist Nikolaus Schobesberger highlighted the potential impact on bathers and water sports enthusiasts, as sharp mussel shells can injure swimmers and easily adhere to boats and gear. To prevent further spread between water bodies, experts recommend that recreational users thoroughly clean, drain, and dry all equipment before moving to different lakes. Authorities are continuing to monitor the biological invasion to assess its long-term ecological consequences for Austrian freshwater systems.
