Hi,

My understanding is that the problem is this: the fish that are being killed
are mostly Gizzard Shad. They are not native to such northern
latitudes--they got into Lake Erie apparently through the Ohio Canal in the
19th Century. It's not the changes of temperature so much as simply the cold
that kills them. I've heard that they can't metablize oxygen at low
temperatures, but don't know this from personal knowledge...
