Lake Ontario ecosystem incorporating invasive zebra and quagga mussels

(08/17/10) An update now on the invasive zebra and quagga mussels. Yesterday, we told you about the Sackets Harbor water treatment plant on the shore of Lake Ontario. It was nearly shut down last week after its intake pipe was so choked with mussels almost no water came through.

This morning, we hear from Dr Dawn Dittman. She's a researcher with the U.S. Geological Survey in Cortland, New York--and one of only a few people tracking the invasive mussels.

She says their numbers appear to be stabilizing. And she tells Jonathan Brown some popular sport fish--native to Lake Ontario--are starting to find zebra and quagga mussels quite tasty.
