The report has a graph that illustrates your point exactly, showing the change from the early 1900s to now. The question of the causes for the decline is exactly what we've been talking about: what those causes are and how we address them.
Are we getting any closer to understanding it? It's a complex question. We have a good sense of the reasons for the decline. For example, a lot has to do with marine survival and those types of aspects that are obviously hard to control. I think, however, that the system we have for managing salmon is a good one. We have good information. We worked well with our stakeholders and first nations groups to come up with an integrated plan to manage the returns that we do have.
