I thought I had heard that zebra mussels were also affecting the fish in the
great lakes. The theory went that the sheer mass of zebra mussels was so
good-in-filtering water of micro-organism that there weren't enough to feed
the slightly larger animals. Since they couldn't find food they were dying
out. The same was happening to the next larger predator like Mooneyes and
on up the food web to the non native salmons, the walleyes, etc. At least
that's what my fishing buddies along Lake Ontario were complaining about.
Has that been the actual affect or are they just using the wrong lures?

If you want to talk about how they us directly, they like current so they
climb all over each other on effluent pipes and anything else that empties
into the lake, forming layers upon layers and eventually clogging it up.
They are super adhesive and hard to remove. This can cause things like
sewer plants or other nasty places backing up and overflowing directly into
the water as well as costing millions of dollars a year to control
chemically or remove.
