Can you please cite one example where sea-going Atlantic salmon have been successfully introduced into a new environment or restored to a watershed where they had been previously extirpated.
All I want is just one example. One successful case study. That is not too much to ask is it?
If you cannot come up with a successful precedent, then why would these conditions you raise actually matter? (Aside from the fact that there is lots of clear-cut logging in New Brunswick and Quebec and yet there are lots of salmon except for a few streams where runs were destroyed by dams or agriculture.)
Do you plan on using prayer circles or waiting for a technological miracle, perhaps genetically-modified Atlantic salmon?
Enso, is there a watershed and ocean anywhere where salmon have been extirpated but where all the conditions I mentioned above have been fully addressed in a restoration effort? All I want is just one example. One case study to show that it was entirely ineffective. That is not too much to ask is it?
Until that is done, it is just as speculative to say that it wouldn't work as it is to say that it would. That's how science works, right? Until someone produces definitive results either way, it remains....Unknown? Yes. Possible? Perhaps. Countless, unsuccessful case attempts at human flight were made for hundreds of years before the Wright brothers got aloft. I'm old enough to remember the extirpation and recovery of other species from brook trout to striped bass in my local rivers. But yes, they are not Atlantic salmon, and their biology and ecology are very different. However, it is also worth noting that at least two Maine rivers - the Kennebec and Penobscot - have very small but still viable populations of breeding Atlantics. They're not completely gone yet.
I realize the near (and some would say, legitimately, complete) impossibility of ever removing all dams on any watershed, pulling all the nets out of the Atlantic, and discovering and reversing whatever ocean conditions are suppressing smolt survival. That's why I said I'm not confident that it will ever happen.
Apparently, that bit of understatement was entirely misinterpreted.
