I'm not aware of any. Certainly, I'm not exhaustive, but I keep in touch with the literature. It seems that wherever you have anadromous salmon or trout runs, there's always an impact. That's the sense I get. Chile doesn't have anadromous salmon runs that are natural. In fact, these are escapees that now run into the rivers from the fish farms, and eventually they naturalize.
I cannot come up with any positive answer for you.
