Could they become a new fresh water plague?

Not that I would suggest tampering with an ecosystem, but Zebra Mussels
are not without some positive aspects. Their filtering capabilities can
improve water quality and clarity. There are reports of areas where the
smallmouth, perch, and even salmon fishing has improved after Zebra
Mussel infestations.

Thank you. I was looking for a link for that.

I read a research report on Great Lakes fishing done by some Ohio
fisheries biologists and their viewpoint that the Zebra mussel was
responsible for the resurgance of Great Lakes fishing.

I konw when I was up on the St. Lawrence Seaway five years or so ago,
the water was clear, clean and you could see pike and other fish
cruising at 15/20 foot depth.
