I'm sorry, but I can't speak to the B.C. situation. However, I have heard of the salmon cannon, and I have done a little research personally on some alternative solutions.
I can't speak to or make recommendations on the hydro dam currently. I think that would be better left to the experts.
I have heard the same, and maybe keeping a fish for an extra year could be very beneficial. I don't believe there are talks about that currently, but it is definitely something that we would be willing to work on with Yukon Energy and all of its partners to try to ensure the fish have the best chance of survival.
We're not professionals in that, so we can't really make a recommendation on how you operate a hydro dam either way.
