Why the quagga mussel could change Swiss lakes forever

  • 3 hours ago
The quagga mussel, an invasive species from the Black Sea, is rapidly spreading across Swiss lakes, posing a serious threat to local ecosystems. First detected in 2014, the quagga mussel has colonized major lakes like Lake Geneva and Lake Constance, outcompeting zebra mussels due to its ability to thrive in deep waters.

00:00The quagga mussel, an invasive species from the Black Sea, is rapidly spreading across Swiss lakes,
00:05posing a serious threat to local ecosystems.
00:08First detected in 2014, the quagga mussel has colonized major lakes like Lake Geneva and Lake Constance,
00:15out-competing zebra mussels due to its ability to thrive in deep waters.
00:20These mussels spread through human activities,
00:23hitching rides on boats and equipment, making their way into new waters.
00:29Experts like Piet Spaak from EAWAG warn that quagga mussels could disrupt lake ecosystems
00:35by depleting plankton, which fish rely on, and clogging infrastructure with their shells.
00:40Ongoing research and prevention measures are vital to mitigate their growing impact on Swiss lakes.
