If a tool was mentioned, I don't think it was about the chemical analyses we're doing, but probably more in the context of major hatcheries. Major hatcheries are seen as a management tool. As you just heard, they can produce large numbers of fish. But the intention in doing that is that you have a certain minimum survival; therefore, it has a cost-benefit factor that they go ahead and build a hatchery. The issue is whether the environment is the same now as it was before. And it's not. So you have to think very carefully about how you're going to invest to do this. It may be that the timing now is much more conducive for small-scale, diverse community hatcheries.
