I did a search and couldn't find a thread on this topic but that doesn't mean there isn't one. I have trouble searching here.

Anyway I was talking with a couple of guys about fishing and we somehow got on the topic of smelt runs that used to be prevalent at Pt Pelee in Canada and the smelt runs in general in the Great Lakes. Although, there are still smelt in the Great Lakes the quantity seems to have dissipated substantially.

I am wondering if anyone out there has any theories or ideas as to why the huge loss of smelt in the Great Lakes? Tks
