Zebra mussels, the nonindigenous species

Zebra mussels.  I hate these frickin' things.  They are choking up my favourite freshwater lakes and rivers.

Zebra mussels originated in the Balkans, Poland, and the former Soviet Union. Biologists believe the zebra mussels were picked up in a freshwater European port in the ballast water of a ship and were later discharged into the Canadian side of Lake St. Clair (blame the Canadians again, eh). A female zebra mussel begins to reproduce at 2 years of age, and produces between 30,000 and 1 million eggs per year.

I took these pictures when we were swimming on the Upper Rideau Lake last weekend.  They stick like snot to a steel pole in -30 degree C.  Did I mention that I hate these damn things?


Wear water shoes when swimming folks, these little bastards are like razors if you step on them just the wrong way.

More warnings, no overnight parking, no bikes, and say no to zebras
