Hello all,
This is my first time posting to this board. I received this e-mail today and I feel it's important enough to warrant posting. This also might be my answer to why there are so many dead fish on my shore, mostly mudcats and what I called mudpuppies.
Regards Mario

> Northern Europe, and in northern Pacific and Atlantic coastal areas.
