We had a large die off in the western basin of Lake Erie recently. In
talking to our DNR folks, they were still clueless as to what could be the
cause. As the link that you posted suggests, I have heard of everything
from bacterial to viral to low O2 levels to temp swings. The temp swings
and the O2 I have a hard time with since it is only the carp that seem to
be dying and there are other fish in their breeding grounds which would be
much more suceptible to these conditions than carp. On an interesting
note, again as suggested, I have heard of the introduced koi herpesvirus
wreaking havoc on the big koi people. This virus has reportedly come in
from large farms in Israel and other middle eastern contries and was
devestating some _very_ expensive koi fanatics and could possibly have been
introduced into the environment. You think that native fish enthusiasts
are fanatics, koi nuts will pay thousands of dollars (sometime even 10's of
thousands) for one fish! To have your collection drop for an unknown
reason is probably like watching the stock maket plummet. Since I don't
have a fortune in koi or stocks, I guess I cannot make the comparison ;-).

What I find interesting is that people call carp garbage fish and a
detriment to gamefish, but when you finally find something that will
exterminate an long term exotic, everyone complains!
