Cottagers fear time running out for containing zebra mussels in Clear Lake
Clear Lake cottage owners fear crucial time is being lost in efforts to contain invasive zebra mussels, after an underwater curtain was dislodged by the wind and waves two days after being installed. For Scott Higgins, a senior research scientist with IISD-ELA, the fact Parks Canada has not reported new discoveries of live adults or "veligers," free-floating microscopic young mussels, is good news. The bad news is that water samples contained environmental DNA, which suggests there could be some living mussels, although likely in small numbers.
