Okay. It's obvious that year-class strength varies with environmental conditions. With walleye, for example, the higher the water, the better the survival, so we have natural fluctuations. I think these are important points because it's important to zero in on exactly what the problem is.
What is the problem with the Fraser River sockeye, then? What are some of the factors that have caused the decline in the low years, keeping in mind that we have these massive runs every four years? Is it international overfishing? Is it habitat loss? What is it?
