Mr. Chairman, I will apologize for what seems like an evasive answer. Please don't take it that way.
For sure, we are looking into these issues; I can say that quite categorically. I'd like to be able to say to you: “We've identified the following impacts in the subdominant years” or “We have identified predator swamping as the cause.” I can't give you that kind of answer.
What we're finding is that first of all, there is far more variability than we expected from system to system. I know the conversation today is focused mostly on the Fraser, but if you started walking up the coast and looked at some of the comparative work in the Skeena and the Fraser, truthfully, sir, part of our answer is that we're scratching our heads. We're finding results that are quite confounding. Part of what we're trying to do is tease out what the various factors at play are here, and we're trying to compare across systems a little bit.
What we are finding is that there is not an enormous difference between what we've described as broad-based impacts in the dominant years and those in the subdominant ones. You can't say that in a particular year this stochastic or one-time event occurred and you can see a response. The inquiry is quite deep and broad. It is not yielding, at this point, the kind of definitive “here's what we're seeing” answer. It's a matter of saying that the work is ongoing, we don't have definitive answers, but we are actively pursuing it.
