Summary: When recreational boats are transported overland, they are often accompanied by zebra mussels, attached to the hull. This alien species, which first appeared in Switzerland in 1960, can thus invade other natural waters. A new study which identified the main transport routes recommends various preventive measures that could at least slow the spread of invasive species. Meanwhile, quagga mussels have also been detected for the first time in the Rhine at Basel.
